TEST PROCEDURES
1 SCOPE
This procedure, when read in conjunction with other
Circulars issued by the Administrator provides sufficient
information, without reference to other standards, to
conduct and audit tests on Seat Belt Anchorages to
demonstrate compliance with Australian Design Rule 5/01
and 5/02 . ADR’s 5/01 and 5/02 have similar test
requirements. ADR 5/00 has been superseded by ADR
5/01 and 5/02. ADR 5/01 differs from 5/02 in that:
• it specifies new seat belt anchorage requirements for
certain Seats in categories MD2, MD3, MD4, ME,
NB2 and NC vehicles.;
• it specifies certain requirements for vehicles where
the driver’s Seat is a Suspension Seat;
• it deletes ECE 14/01 as an acceptable Alternative
Standard; and
• ADR 5/02 is extended to LE vehicles
Provided that, where appropriate, ECE 14/02 was used as
the Alternative Standard, vehicles certified to the
requirements of any of the Acceptable Prior Rules as
shown in the Applicability Table of the ADR for a
particular category shall be deemed to comply with this
Rule.
Vehicles complying with ADR 34/.. “Child Restraint
Anchorages and Child Restraint Anchor Fittings” need not
comp ly with the “Child Restraint Anchorage”
requirements of this ADR.
Where particular requirements apply to one of the two
ADR’s it is noted in the text.
For convenience reference to the relevant ADR clause
number is quoted in brackets against each appropriate
paragraph of this procedure.
The equipment, orders of accuracy and step by step
actions described in this procedure are drawn from the
standards and recommended practices quoted in the ADR
and from accepted laboratory practices. While
conformance with this procedure is sufficient to
demonstrate compliance with the ADR, other equipment,
orders of accuracy and procedures may be used provided
it can be shown that they demonstrate compliance with the
ADR.
This ADR calls for tests which demonstrate that
(i) the locations of all final anchorages and sash guides are
within specified zones relative to the Seating Reference
Planes and
(ii) the strengths of all anchorages and sash guides meet
certain minimum requirements and
(iii) the deflection of the seat belt mounting system under
load will not result in excessive forward movement of the
restrained occupant under impact conditions.
Static test methods only are specified for seat belt
anchorages.
For child restraint anchorages static or dynamic test
methods may be employed.
Note that tests on seats and their anchorages to
demonstrate compliance with ADR 3/01 - Seat
Anchorages, may be conducted in conjunction with seat
belt and child restraints anchorage tests, where if the seat
Issue 2:
CIRCULAR 5/02-9-1
belt or child restraint anchorages are mounted on the seat.
Refer to Circular 3/01-9-1 for details.
This procedure is intended primarily as a guide for
Officers of the Australian Department of Transport and
Communications or Agents acting on behalf of the
Administrator when they carry out audit inspections of
Test Facilities or witness tests for compliance with the
ADR. This and other Circulars dealing with Test
Procedures for ADRs may also be useful to vehicle
manufacturers and testing organisations.
Nothing in this Circular, however, absolves the
manufacturer from complying with the requirements as
specified in the ADR which always remains the primary
reference.
2 SELECTION OF TEST COMPONENTS
This procedure applies to all seat belt mounting systems
(unless specifically exempt) and child restraint anchorages
in vehicles subject to the Design Rule. Forward facing,
rearward facing and side facing seats requiring belts are
also included.
See Applicability Table in Annex A showing the type of
seat belt and anchorage required for vehicle categories for
ADR 5/01 and 5/02.
All load testing must be conducted on a representative
body shell or section thereof large enough to ensure that
during testing any body distortion due to seat belt loads
are contained within such section.
Some fittings for loading the anchorages may be replaced
by stronger or stiffer representative items for the test.
Where the tests involve seats because the belt anchorage is
attached to the seat, or the seat significantly affects the run
of the belt, or the child restraint is located in the vehicle
body structure more than 100mm below a horizontal
plane tangential to the top point of rear seat back, then
such seats must be structurally representative of
production and include all hinges, seat mechanisms and
fixings including those which secure the seat to the
vehicle.
3 IDENTIFICATION OF TEST COMPONENTS
The body structure, seat belt fittings and any seat frame,
adjusters, hinges and linkages shall be structurally
representative of the design condition as reflected in the
production drawings.
Further, if dynamic testing is employed for child restraint
anchorage testing, the test facility must ensure that
kinematically the mechanisms are also representative of
the design conditions.
If production parts are being tested they should be drawn
from a batch which has passed normal quality assurance
procedures. They should then be identified against the
production drawings. If prototype parts are being tested
they should be individually inspected on a component by
component basis for both dimensional and material
(composition, heat treatment, finish and welding)
compliance with the drawing.
In either case the revision or issue status of the drawing to
Page 5 of 24
CIRCULAR 5/02-9-1
CIRCULAR 5/02-9-1
TEST PROCEDURES
which the assemblies have been checked must be stated
on all test records.
Finally, a build record should be prepared showing the
source and status of all material used including any body
section employed. Should any used or out of specification
material be employed, its use should be recorded and
justified. The record should be of sufficient detail to
completely identify the subject material.
4 NUMBER OF TEST ASSEMBLIES
Usually one body shell and one front seat set and one rear
seat are sufficient to fully validate the model range
employing one basic body. Unusual vehicle configuration
or designs which provide a wide range of interior layouts
may require more than one body shell.
Body and Seat structures may be used for more than one
test providing the distortion (if any) produced in earlier
testing is minimal and would not affect subsequent tests.
5 EQUIPMENT
5.1 Dimensional and General Tests
These tests are usually conducted in the drawing office
using full scale body layout drawings or computer aided
drafting techniques. The equipment required comprises a
2-D manikin, see Circular 0-12-6, and normal drafting
equipment.
The vehicle manufacturer’s occupant package drawings
are required to determine the location of the Seating
Reference Point and the Seating Reference Plane. From
this data, using conventional drafting techniques the
Dimensional Tests given in Section 6.1 can be conducted.
5.2 Load Testing - Static Tests
5.2.1 Basic Equipment
5.2.1.1 Test rig or rigs for rigidly securing a
vehicle body (or whole section thereof) and
providing mounting points for one or more static
load ap plicato rs as determined by the
configuration of the seat belt or child restraint
anchorages.
5.2.1.2 Fixtures. These are limited to the brackets
necessary to secure the body being tested to the
test rig. It is usual to attach the body via the
suspension mounting points and, if necessary at
additional points along the underframe, while
ensuring that the attachments do not reinforce the
body structure in the area of the seat belt
anchorages. Note that for all child restraint tests
the associate seat or seat back must also be
installed in the body.
5.2.1.3 Adjustable, static load application system
capable of applying the following loads along a
line from the appropriate sash location point for
each affected seat to the corresponding upper torso
reference point:-5N
- 900 N (Clause 5.6)
- A static load application system capable of
CIRCULAR 5/02-9-1
Page 6 of 24
applying a 50 N load for one second in a
transverse horizontal direction to a seat back
mounted sash guide.
5.2.1.3.1 Typically this system comprises a dead
weight or hydraulic system capable of exerting
smoothly a load of 2 N to 1 kN over a stroke of
200 mm within 60 s and of maintaining the load
for 10 seconds. Where a vehicle incorporates two
Child Restraint Anchorages, a single actuator with
a ‘balance bar’ providing equal load to each
anchorage is often used. Where more than two
anchorages are provided, two or more actuators
are usually employed with a control system to
ensure simultaneous load application.
5.2.1.4 Adjustable, static load application see also
Annex A Table 1 for loads Typically this
comprises three hydraulic cylinders which can be
adjusted in position to apply loads in longitudinal
vertical planes as follows:- 2 loads of 22 kN (9.0 kN for rear facing seats) at
5 to 50 degrees above the horizontal
- 1 load of 17.7 kN (7.0 kN for rear facing seats) at
0 to 20 degrees above the horizontal.
- 3.4 kN for each Child Restraint Anchorage in the
direction given by the ‘line of action’. See Section
6.1 see also Annex A Table 1 for loads
5.2.1.5 For multiple anchorages on pillars near
front seats the equipment in Section 5.2.1.4 may
be set up to the loads in Clause 5.2.9 for an
additional test or alternatively an additional load
applicator used to provide 13.3 kN load between 0
to 20 degrees above the horizontal.
5.2.1.6 Where seat belt or child restraint
anchorages are mounted on seats, (or in the case of
child restraint anchorages being located in the
vehicle body structure more than 100mm below a
horizontal plane tangential to the top point of rear
seat back) sufficient additional load applicators are
required to provide simultaneously the seat
belt/child restraint loads and ADR 3/01 - ‘Seat
Anchorages’ loads - refer to Circular 3/01-9-1.
5.2.2 Control. Where the tests can be conducted
using only one actuator each load can be
conveniently varied manually and the load
increased using a single readout device until the
required load level is reached. Where, because of
the seat belt anchorage configuration, more than
one actuator is required, some form of automatic
control for each actuator is desirable. Typically
this comprises a separate hydraulic circuit for each
actuator each with its own pressure limiting valve
which can be pre-set to the desired load thus
ensuring that the correct loads are applied
simultaneously to each item under test.
5.2.3 Body Blocks etc. Clause 5.5.3 specifies that
loads shall be transmitted using body blocks and
Clause 5.5.4.1 specifies attachments which are
representative of a seat belt. Typical body blocks
are shown in Annex A and typically the belt
representation is made by sewing approximately
Issue 2:
TEST PROCEDURES
four layers of seat belt webbing together and
incorporating end fittings of thicker material than
production. This latter approach reduces belt
stretch, thus preventing the load cylinder running
out of travel and ensures that the belt fittings do
not fail as they may be subjected to many tests.
5.2.4 Instrumentation. Each required load actuator
must be provided with its own independent load
indicator. Again, where the tests can be conducted
using only one actuator a simple single indicator
may be adequate. Where, because of the seat belt
or child restraint anchorage configuration more
than one actuator is required, instrumentation with
multi-channel recording is usually required to
provide the necessary indication of loads.
5.2.4.1 Measurement. Usually two parameters,
load and time, are measured. This is typically
achieved by a load cell and associated electronic
equipment which is suitable for multi-load
actuation cases as it provides both individual load
monitoring during application and multi-channel
recording. Where the tests can be conducted using
only one actuator a simple readout device, such as
a pressure gauge, may be used and each reading
recorded manually. In this case adequate
calibration under quasi-static conditions to
determine the effect of seal friction etc. must be
made.
In some cases the deflected position of a sash
guide or contact point between seat and seat belt
must be determined. This is typically achieved by
establishing prior to the test a datum - e.g. rigid
rectangular bar - relative to an area of the body
which will not be distorted by the test. The
deflected position of the subject part is then
measured using hand instruments relative to this
datum while the load is applied.
5.2.4.2 Recording. Where automatic recording is
used multi-channel light beam or pen recorders are
suitable as they allow immediate reading to ensure
that th e requ ired lo ads ar e achieved
simultaneously in all actuators. One recording
channel is required for each actuator. A system
response of 10 Hz is satisfactory. The internal
time line generator in the recorder or an external
time base signal is usually used for time
measurement. Where single channel manual
recording is used, a stopwatch may be used to
check test the load is held for at least 1 second.
5.2.4.3 Order of Accuracy. Except where specified
in the ADR or referred documents, the following
o rder o f accu racy is considered to be
commercially achievable and should be taken as a
guide. Instrumentation of lesser accuracy is
acceptable provided it is taken into account in
determining the certainty of results.
The time measurements should be determined
within 1% . The order of accuracy of load
measurement may vary, depending on the system
employed. In all cases, however, the tests must be
Issue 2:
CIRCULAR 5/02-9-1
conducted with the load reading equaling the
calculated load plus maximum instrument error. A
typical instrument system for load measurement
wou ld h ave an order of accuracy of 5%.
Deflection measurements should be made within
+/− 3µµ.
5.2.4.4 Calibration. Routine calibration of load
cells, electronic elements and recording equipment
is to be carried out in accordance with Circular
0-12-3. Prior to each series of tests it is desirable
that the complete load measuring system be
calibrated against a known standard, e.g.
deadweight, universal testing machine or transfer
calibration system at a number of points.
5.3 Dynamic Testing (Child Restraint Anchorages
Only)
Page 7 of 24
5.3.1 Basic Equipment.
5.3.1.1 Impact sled system with the following
features:
- Minimum basic sled mass of 380 kg (including
vehicle body or section thereof and complete rear
seat).( Clause 5.11.4.3.4)
- Capability of imparting a velocity change of at
least 49 km/h to the above sled to which a mass of
21.4 kg for each Child Restraint Anchorage has
been rigidly attached. The sled may be
decelerated from 49 km/h to zero or may be
decelerated to zero and then accelerated in the
reverse direction to achieve required velocity
changes.
- Capability of achieving during the velocity
change a deceleration of 235 to 335 m/s2 within
30 ms and maintaining that deceleration for 20 ms
except for periods of less than 1ms.(Clause
5.11.4.3.5)
5.3.1.2 Test Dummies. One dummy with a mass
of not less than 21.4 kg is required for each Child
Restraint Anchorage provided in the vehicle under
test. Details of the dummy described by the
drawings produced by the TNO (Research
Institute for Road Vehicles) Netherlands for a 50th
percentile 6 years old child may be found in
Annex B. ( Clause 5.11.4.3.1)
5.3.1.3 Fixtures. For dynamic testing the only
fixtures required are those to allow the body shell
(or part thereof) to be mounted to the sled to
achieve a deceleration while traveling forward.
These must be as rigid as feasible to reduce
structural “ringing”.
5.3.2 Instrumentation. Sufficient equipment is
needed to ensure that the required velocity and
deceleration levels have been achieved.
5.3.2.1 Measurement. Time, initial velocity, final
velocity, and the deceleration of the vehicle in the
Child Restraint anchorage area are the only
parameters requiring measurement. In practice
this means measuring the deceleration of a rigid
body structural member close to the Child
CIRCULAR 5/02-9-1
CIRCULAR 5/02-9-1
TEST PROCEDURES
Restraint anchorage. A minimum of two
decelerometers, one on each side is required
together with their associated electronic systems
which must have a flat frequency response within
5% from 1 to 1000 Hz.
It is the responsibility of the Test Facility to
demonstrate that the transducers used have
measured the acceleration of the test structure.
Speed is typically measured just prior to
commencement of and, in the case of a system
which accelerates the sled rearwards again, at the
end of the deceleration pulse by measuring the
time taken for the sled to pass through a “gate”
using photoelectric cells or similar devices and
associated electronic circuits. The velocity change
is determined from the speed calculations taking
directional sense into consideration.
5.3.2.2 Recording. A multi-channel high speed
data acquisition device is required. If a light beam
recorder is used a paper speed of 1.5 m/s
minimum is usually satisfactory with
galvanometers having a flat frequency response
from one to 1000 Hz. One channel is required for
each accelerometer and one for the signals from
the speed gate. This type of recorder has the
advantage that it gives immediate readout. The
recorder may have inbuilt timing line generation
facilities to produce lines at 10 ms intervals.
Alternatively an external time base source may be
used.
5.3.2.3 Order of Accuracy. Timing lines should be
within 1% accuracy. Total deceleration and
velocity measurement system accuracy should be
within 5%.
5.3.2.4 Calibration. When decelerometer,
amplifier and recorder accuracy are all taken into
account achieving the required accuracy for
deceleration measurement will mean system
calibration, prior to each test, against a known
stand ard, e.g. shaker table or reference
accelerometer. This is over and above the routine
calibration for each element in the system which
should be carried out in accordance with Circular
0-12-3.
5.3.2.5 Calibration of test rig
See Section 6.2.7.4.2
6 PROCEDURES
6.1 Dimensional and General Testing (Seat Belt
Anchorages)
6.1.1 Seating Capacity. Determine the effective
cushion width of each seat as per Clause 5.7.3. In
accordance with Clauses 5.7.1 and 5.7.2 identify
the single and multiple seats and the seating
capacity of each seat and the complete vehicle.
See Annex A Tables for application of seat belt
type to the various categories of vehicle for ADR
5/01 and ADR 5/02.
6.1.2 Seating Reference Plane
CIRCULAR 5/02-9-1
Page 8 of 24
6.1.2.1 Determine driver’s Seating Reference
Plane . For bench seats and as an optional
procedure for individual seats this is the Vertical
Longitudinal Plane though the geometric centre of
the eye ellipse as described in Circular 0-12-6 and
0-12-7.
For individual seats the Seating Reference Plane
may be taken as the longitudinal vertical plane
through the geometric centre of the seat but must
not be further inboard.
6.1.2.2 Determine Seating Reference Plane for
Other Positions. The Seating Reference Planes for
other positions are described in ADR Definitions
‘Seating Reference Plane’ Sections (ii), (iii), (iv) .
6.1.3 Seating Reference Point. This is the
manufacturer’s nominated reference point for each
seat as described in ADR - Definitions. Refer to
Circular 0-12-6. It conventionally defines the
rearmost normal driving and riding position of the
95th percentile male.
6.1.4 Seat Back Angle. Two seat back angles are
to be established. The Design Seat Back Angle is
that nominated by the manufacturer and defined in
Clause 5.1.15 while the maximum angle for this
design rule is the largest angle up to and including
30 degrees at which the seat back can be set.
6.1.5 Normal Driving and Riding Seat Track
Travel. This is as nominated by the vehicle
manufacturer but may be taken as the fore and aft
seat movement for which seat adjustment is
provided. Seating positions rearward of those
provided for the 95th percentile male are not
considered normal driving and riding seat track
travel.
6.1.6 Pelvis Reference Point and Locus. Establish
the pelvis reference, locus and pelvis reference
point as follows:
6.1.6.1 Pelvis Reference Locus - the locus of a
point fixed relative to the Seat, coincident with the
Pelvis Reference Point when the Seat is in the
rearmost design position and extended over the
design or riding range of Seat travel.
6.1.6.2 Pelvis Reference Point - a point used in
simulating the correct position of a lap Strap or the
lap Strap of a Lap-Sash Belt. It is the point which
is located at a height of 95 mm above and 70 mm
Forward of the Seating Reference Point.
These points take into consideration seat travel
and any increase in seat height which is
automatically provided by the seat adjusters.
6.1.7 Seat Position Classification. Determine
whether each seating position is inboard or
outboard in accordance with ADR Definitions
which define an outboard seating position as:- ‘a
forward or rearward facing seating position nearest
a vehicle side wall where any part of the top of the
seat cushion is within 200 mm of the side wall.’
6.1.8. Provision of Anchorages. Confirm that for
each seating position (except where specifically
excluded):Issue 2:
TEST PROCEDURES
- two lap anchorages are provided (Clauses 5.2.3 5.10.2.1)
- upper torso restraint is provided (Clauses
5.2.4.1.2 - 5.2.4.2 - and for ADR 5/02 Clause
5.10.0)
6.1.9 Seat Belt Configurations Required. By
reference to the Tables in Annex A describing the
seat belt required for each seating position of all
vehicles for ADR 5/01 and ADR 5/02 establish
that the appropriate seat belt is provided for each
outboard seating position and that anchorages for
the necessary retraction mechanisms are provided.
6.1.10 Sash Guide Classifications. Determine for
each seating position with upper torso restraint
whether the sash guide is a component of a seat
belt or not according to Clause 5.3.1.1 and
whether it is load bearing or not according to
Clause 5.3.1.2.
Establish for each seating position with upper
torso restraint the type of sash guide provided
with, or for, the seat belt.
The types are:A. Sash guides which are the anchor fittings at
final torso anchorages and are the only sash guides
in the system. These are load bearing sash guides,
components of seat belt assemblies and sash
location points.
B. Sash guides which are the only sash guides
additional to the anchor fittings at the final torso
anchorages. These are load bearing sash guides,
components of seat belt assemblies and sash
location points.
C. Sash guides other than types A and B described
above.
6.1.11 Design of Anchorages. Establish:- that seat belts can be readily replaced (Clause
5.2.2);
- that any adjustment the sash location point or
guides can be affected without tools (Clause
5.4.2.2.3);
- which anchorages are designed to accept more
than one anchor fitting. These are to be considered
as two (or more) anchorages (Clause 5.2.8) for
testing purposes.
6.1.12 Location of Anchorages and Sash Guides
6.1.12.1 Lap Anchorages. Establish that the lap
anchorages associated with each seating position
comply with Clauses 5.4.1.1, 5.4.1.2, 5.4.1.3.1,
and for vehicle categories MD3, MD4, ME, NB2
and NC with Clause 5.10.2. Establish whether
the length of the strap between lap anchor point
and pelvis reference point measured along the
centre line in side view of the strap installed
exceeds the direct distance by more than 60 mm
(Clause 5.4.1.3.2). If not, the design complies
with this Clause. If it does exceed 60 mm then the
deflection of the seat must be measured under load
to determine compliance. In this case reference
should be made to Section 6.2.4.
6.1.12.2 Sash Location Point. Establish on the
Issue 2:
Page 9 of 24
CIRCULAR 5/02-9-1
drawing the nominal line of the belt strap from the
Sash Location Point to the Upper Torso Reference
Point. Establish the transverse distance ‘S’ for the
Sash Location Point according to Clause 5.1.18
and areas A and B as defined in Clause 5.9.1 and
Clause 5.9.2. respectively.
Then confirm:- that, if non adjustable, the Sash Location Point
has a minimum of 140 mm ‘S’ dimension and lies
in Area A (Clauses 5.4.2.1.1 and 5.4.2.1.2)
- that, if adjustable, at least one point complies
with the requirements of Clause 5.4.2.1.1 and that
the minimum height requirements of Clause
5.4.2.2.2 are met;
- that, if the sash guide is non-load bearing, the
next load bearing sash guide lies in Area A or Area
B (Clause 5.3.7.1) and that the 60 mm rule in
Clause 5.3.7.2 is met for both the design seat back
angle and the maximum seat back angle (Clause
5.3.9).
6.1.12.3 Harness Anchorage. Determine for a
single point harness anchorage that it lies at least
500 mm behind the Torso Reference Line, within
50 mm of the Seating Reference Plane and within
Area B in side view (Clause 5.4.3.1). Determine
for two point harness anchorages whether they lie
at least 75 mm behind the Torso Reference Line,
within Area B and meet the transverse location
requirements of Clause 5.4.3.2.
6.1.13 Adjustable Anchorages and Sash Location
Points. Where adjustment is provided, the
structural implications of applying the loads
described in Section 6.2 at every point over the
adjustment range must be analysed and a suitable
test program devised.
6.1.14 Anchorages on Pillars. Where a lap
anchorage is located on a pillar close to the front
row of seats, the requirements of Clause 5.2.9
should be checked to determine whether the
additional load test requirements of that Clause are
met. If so the program in Section 6.2.4 must
include these tests.
6 .1 .1 5 Sash Guid e Gen eral. Using the
classifications in Section 6.1.10:6.1.15.1 Sash Guide Types A and B. Confirm that
the strap cannot be removed from the guide
without the use of tools or that the automatic
return requirements of Clause 5.3.5 are met and
that the sash guide has been validated for both the
dynamic testing procedure of ADR 4/00 ‘Seat
Belts’ and the static strength of assembly test in
the Australian Standard 2597 - 1983 Method of
Testing Seat Belts as quoted in ADR 4/—.
6.1.15.2 Sash Guides - Type C. Confirm that the
strap cannot be removed from the guide without
the use of tools or that the automatic return
requirements of Clause 5.3.5 are met (load bearing
sash guides only) and that the sash guide has been
validated against the following Clauses of ADR
4/00 :CIRCULAR 5/02-9-1

- 4/01.2.7 - AS 2597.13 1983 - Determination of
Dynamic Performances requirements
- 4/01.3.3 - Belt end requirements
- 4/01.5.1 - Belt cycling, and
Also confirm that where the seat back is the sash
guide, the strap cannot fall below the lower area of
Area A under the conditions of Clause 5.3.4.
6.1.16 Dimensional Test - Child Restraint
Anchorages. Using the manufacturers occupant
package check that the SAE 2D manikin, see
Circular 0-12-6, is positioned relative to the rear
seat(s) and determine the location of the Seating
Reference Point(s) and the Torso Reference
Line(s) in side view. (Refer ADR Definitions for
Seating Reference Plane and Seating Reference
Point).
6.1.16.1 Determine that each adult Seating
Reference Plane nominated by the manufacturer in
plan view is:
(a) for seats designed for only one occupant, the
vertical plane through the geometric centre of the
seat.
(b) for seats designed for two occupants, in the
case of outboard seating positions, at least 200 mm
from the vehicle centreline and at least 200 mm
from the vehicle inner panel (or the line of the
panel) measured transversely through the Seating
Reference Point.
6.1.16.2 (Clause 5.1.7). Determine the Design
Line of Action in side view by drawing a line from
the Upper Anchor Fitting ( Figure 4 of ADR 5/00)
located using the Australian Standard 1754
‘Recommended Fixings and Spacers’ (Figure 5 of
ADR 5/00) to the Shoulder Point (300 mm above
the Seating Reference Point) measured along the
Torso Reference Lines), deflected if necessary by
the seat back. (Refer Annex B - Test Equipment
Diagrams).
6.1.16.3 (Clause 5.11.4.2.1). Determine the
direction of Test Load (static testing). This is to be
within 20 degrees of the Design Line of Action
and not more than 5 degrees to the left or right of
the longitudinal axis of the vehicle except where
the Design Line of Action is determined by the
seat back and the upper anchorage is more than
100 mm below the top of the seat back. In this
case the direction of test load shall be within
5 degrees of the longitudinal axis of the vehicle
through a point at the top of the seat back via a
flexible strap connected to upper anchorage.
6.1.16.4 (Clause 5.11.1.1). For passenger cars
(MA) determine that one Child Restraint
Anchorage is provided for each adult Seating
Reference Plane except where a rear seat back is
divided for individual folding into two or more
sections and a division lies substantially on the
Seating Reference Plane of a middle seating
position when a child restraint anchorage need not
be provided for that seating position.
For MB, MC and MD1 Category vehicles
CIRCULAR 5/02-9-1
Page 10 of 24
determine that one anchorage is provided for each
rear seat with a minimum of three anchorages if
more than three seating positions are provided
with adult seat belt assemblies (Clause 5.11.1.2)
except where a rear seat back is divided into two
or more sections which may be folded
independently of each other and the division
between sections lies substantially along the
seating reference plane of the middle seating
position a child restraint anchorage need not be
provided for that seating position (Clause
5.11.1.2.3)
6.1.16.5 (Clause 5.11.1.3). Ensure that the
anchorage incorporates an internal thread of 5/16
inch - 18 UNC - 2B.
6.1.16.6 (Clause 5.11.1.4.2). Ensure that no items
need to be removed to gain access to the
anchorage except closure plugs and items movable
without the use of tools.
6.1.16.7 (Clause 5.11.1.5). Ensure that the vehicle
handbook or other data supplied with the vehicle
includes:
(a) The warning specified in Clause 5.11.1.5.1.
(b) Details of fixings, including spacers which are
required to install the Child Restraint Anchor
Fitting.
(c) The correct length of bolt.
Check that the bolt and fixings in (b) and (c)
achieve at least 5 (five) full threads of engagement.
6.1.16.8 (Clause 5.11.2.1). Check that each Child
Restraint Anchorage lies within 40 mm of the
corresponding Seating Reference Plane.
6.1.16.9 (Clause 5.11.2.2). Check that anchorages
are wholly within the vehicle.
6.1.16.10 (Clause 5.11.2.3). Check that each
anchorage is located rearwards of a line 140 mm
rearward of and parallel to each corresponding
Torso Reference Line - see Annex B(d).
6.1.16.11 (Clause 5.11.3.1). Check that with the
fixing s an d b olt leng th sp ecified by the
manufacturer, the Upper Anchor Fitting can be
installed using a 5/16 inch - 18 UNC hexagon
headed bolt using hand tools and that no
obstruction prevents 5 full threads of engagement.
6.1.16.12 (Clause 5.11.3.2). Check that sufficient
clearance exists around the anchorage to latch and
unlatch the Child Restraint Attachment Clip
(Figure 3 of ADR 5/01 or 5/02) to the Upper
Anchor Fitting with that fitting installed to the
manufacturer’s specification.
6.1.16.13 (Clause 5.11.3.3). If the manufacturer
specifies spacers, check that they conform to the
dimensions in Figure 5 of ADR 5/01 or 5/02.
6.1.17 Post Test Dimensional Checks. The tests in
Section 6.1.1 to 6.1.16 inclusive can be conducted
in the drawing office. The following dimensional
checks must be made where appropriate using the
locations determined under the appropriate loads
to establish that critical deflections are not
excessive.
Issue 2:
TEST PROCEDURES
- Seat deflection - see Section 6.1.12.1.
- Sash Location Point - the location requirements
in Section 6.1.12.2 must be met under 5 N and
900 N loads as per Clause 5.4.2.1.
- Sash guide deflection. For load bearing sash
guides not part of a seat belt assembly, the
requirements of Clauses 5.3.8 are to be met under
an 8.5 kN load as per Clause 5.6.2 for both the
design back angle and the maximum back angle as
per Clause 5.3.9.
Note that, where sash guides are loaded prior to
the measurement of the Sash Location Point, the
“S” distance may be altered from the no load
position which would change the shape of Area A.
Hence the lateral location of the loaded Sash
Location Point must be checked for all load
conditions, i.e. 5N, 900N and 8.5 kN.
6.2 Load Testing - Seat Belt Anchorages
6.2.1 Sash Guide Strength (Clause 5.3.3) - Type B
and C Sash Guides Only.
6.2.1.1 Preparation. With the vehicle body
mounted on the test rig and the upper torso
restraint system (including the seat if the seat belt
run touches the seat together with a representation
of any automatic belt adjuster) installed, set the
load applicator at the correct angle to apply a
tensile belt load from the Sash Location Point to
the Upper Torso Reference point. Set up datum
lines to allow the deflected Sash Location Point to
be measured.
6.2.1.2 Test. Apply a 5 N load and measure the
deflected Sash Location Point which is the point
on the belt centreline where the strap first changes
direction after leaving the Upper Torso Reference
Point.
Repeat with a 900 N load.
Repeat for each sash guide requiring testing.
6.2.1.3 Determination of Results. Transfer the
measured data to the vehicle layout drawing - refer
to Section 6.1.12.2 - and confirm that:- there is no substantial distortion;
- the sash guide remains integral with the
structure;
- the deflected Sash Location Point remains within
Area A after allowing for any change in Area A
due to change in ‘S’ distance.
6.2.1.4 Reporting Results. The results of each test
are to be recorded in a complete internal report
giving a full description of material tested,
equipment used, results and order of accuracy. For
submission to the Administrator the determined
results for loads, deflected position and distortion,
are to be recorded together with the internal report
number in the appropriate section of the Summary
of Evidence Report. See Section 8.
6.2.2 Sash Guide Deflection (Clause 5.3.8) - Load
Bearing, Type C Guides Only.
6.2.2.1 Preparation. Repeat the setting up as per
Section 6.2.1.1 except that a load applicator
capable of 8.5 kN is required and a reinforced seat
Issue 2:
Page 11 of 24
CIRCULAR 5/02-9-1
belt strap is desirable. The sash guide and its
mounting must be representative of production.
6.2.2.2. Test. Repeat Section 6.2.1.2 except that
an 8.5 kN load is to be used.
Repeat for each sash guide/guide position
requiring testing. Note that a range of positions
may need testing for adjustable guides.
6.2.2.3 Determination of Results. Transfer the
measured data to the vehicle layout drawing - refer
to Section 6.1.12.2 - and confirm that the length of
that belt strap from final anchor point to Upper
Torso Reference Point via the sash location point
has not been reduced by more than 60 mm as a
result of sash guide deflection.
In the case of non adjustable sash guides confirm
that the deflected Sash Location Point lies within
Area A or Area B allowing for any change in Area
A due to change in ‘S’ distance.
Where an adjustable seat back affects these results,
the test must be conducted with the seat back at
both the design angle and the maximum angle
(Clause 5.3.9).
In the case of adjustable sash guides, confirm that
at no point in the adjustment range (refer Section
6.1.13.) does the deflected sash location point fall
below plane DJ or CE in Figures 1 and 2 of the
ADR.
6.2.2.4 Reporting Results. See Section 6.2.1.4.
6.2.3 Sash Guide Strength - Seat Back Mounted
Guides (Clause 5.3.4).
6.2.3.1 Preparation. Where a seat back forms a
sash guide in conjunction with a positive
restraining device mounted on the seat back, set
the 50 N force applicator up to produce a lateral,
horizontal force away from the Seating Reference
Plane. This may be performed with the seat in any
position or mounted on a rig plate out of the body
shell.
6.2.3.2 Test. Apply a 50 N load for a minimum of
1 sec to the restraining device.
6.2.3.3 Determining Results. Determine that the
restraining device will withstand the 50 N load.
6.2.3.4 Reporting Results. See Section 6.2.1.4.
6.2.4 Seat Belt Anchorage Strength - All Systems.
Vehicle Categories MA, MB, MC, MD1, MD2,
NA and NB1 (Clause 5.21.1)
(Alternative
requirements for vehicle categories MD3, MD4,
ME, NB2 and NC - Clause 5.2.0.1.2) - (see
Section 6.2.6).
6.2.4.1 Preparation for Test. Review the program
of tests for the model range and confirm that the
worst case criteria in Section 2.2 have been met
and that the loads specified in Clause 5.2.6.4 and
shown in Annex A Table 1 are to be applied to the
appropriate anchorage pairs as specified in Clause
5.5.4.1 and shown in Annex A Table 2.
For each test, set the load applicators so that the
direction of loading for each body block meets the
direction of loading requirements of Clause 5.5.5.
Where one or more seat belt anchorages are
CIRCULAR 5/02-9-1
CIRCULAR 5/02-9-1
TEST PROCEDURES
located on a seat ensure that the seat and its
anchorages are mounted to the body using
production fixings set to minimum specified
torque and set in the rearmost position. Also
ensure that an additional load applicator is set up
to produce a forward load of 20 times the
complete seat weight as specified in ADR 3/01.
Refer to Circular 3/01-9-1. If the doors comply
with ADR 2/00 they may be closed otherwise they
are open or removed (Clause 5.5.1).
In cases where the line of belt pull causes the belt
to contact any part of a seat ensure that a
representative seat or section thereof is mounted in
the body in the production manner and set in the
rearmost position(Clause 5.5.2).
In cases where the length of the lap strap between
anchor point and pelvis reference point measured
along the installed belt centre line in side view
exceeds 60 mm more than the direct distance
between these points (due to seat interference), set
up a datum to allow seat deflection under belt
loads to be established. Refer to Section 6.1.12.1.
Ensure that any load bearing sash guide and its
mountings are representative of production unless
the guide design has been validated as part of a
seat belt assembly test. In the latter case a
strengthened guide of the correct geometry may be
employed for the anchorage test. Clause 5.5.4.2.2.
Ensure that the loading belt passes through all load
bearing sash guides. Belts may by-pass non load
bearing guides for this series of tests - Clause
5.5.4.2.1.
Review the instrumentation, set scales and zeros
and check load settings and calibration by
artificially restraining the load actuators and
applying the full test load plus allowance for
instrument error simultaneously to all anchorages.
Apply a small settling load to the body blocks and
ensure that sufficient travel is available from the
load actuators.
6.2.4.2 Test. Operate the test rig and ensure that
the required net loads are applied for a minimum
of one second. Where required record the
deflected position of the seat at the point(s) of
contact of the belt strap with the seat. Transfer
this data to the package layout, refer to Section
6.1.12.1, and ensure that the path of the belt strap
around the deflected seat is, in side view, such that
the 60 mm requirement of Clause 5.4.1.3.2 is met.
6.2.4.3 Determination of Results. Where results
are achieved by direct readout devices the figures
are to be recorded directly. Where recorders are
used the results are to be determined as soon as
possible after the test. Confirm instrument
calibration. Any charts etc. are to be retained as
original data.
6.2.4.4 Reporting Results. - See Section 6.2.1.4.
6.2.5 Strength Test on Pillars with Multiple
Anchorages (Clause 5.2.9). When a pillar
connecting roof structure to underframe structure

is designed to accept upper torso loads and a lap
anchorage load, an extra test comprising
simultaneous application of loads to the lap body
block and an upper torso body block is necessary.
This test may be incorporated in the tests in
Section 6.2.4 or may be an additional test as
described below.
6.2.5.1 Preparation. For this test strengthened
anchor plates and sash guides may be used
provided the production geometry is reproduced.
For this test the seat need not be fitted.
Set the body blocks and load applicator to apply a
total of 26.6 kN comprising at least 13.3 kN to the
upper torso body block and the remainder to the
lap body block.
Ensure that the loads are applied in longitudinal
vertical planes with the lap anchorage loads
between 5 degrees and 50 degrees above the
horizontal and the upper torso load between 0 and
20 degrees above the horizontal.

6.2.6.1.1 Preparation. Review the program of tests
for the model range and confirm that the worst
case criteria in Section 2.2 have been met.
6.2.6.1.1.1 For Lap Anchorages, the pair shall be
tested simultaneously and the attachments shall
pass round an appropriate body block to which the
load specified in Clause 5.10.3.3 of 9 kN is
applied at an angle of between 5 degrees and 50
degrees.
6.2.6.1.1.2 Final Torso Anchorage shall be tested
simultaneously with the anchorage common to
both pelvic and upper torso restraint and the
attachment shall pass round an appropriate body
block to which the load specified in Clause
5.10.3.3 of 9 kN is applied at an angle of between
0 degrees and 20 degrees.
Where one (or more) seat belt anchorage is located
on a seat ensure that the seat and its anchorages
are mounted to the body using production fixings
set to minimum specified torque and set in the
rearmost riding position and adjusted for height
(where applicable) to achieve the manufacturer’s
Seating Reference Point location.
6.2.6.1.1.3 For ADR 5/02 in the case of an NB2
