TEST PROCEDURE
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 ‘Child Restraint Anchorage(s)’
to demonstrate compliance with Australian Design Rule
34/00 and 34/01. ADR 34/00 differs from 34/01 in that
the ‘Manufacturer’ is required to supply one ‘Child
Restraint Anchor Fitting Package’ installed in the vehicle.
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 ‘Child Restraint’
anchorages and anchor fittings are within specified zones
relative to the ‘Seating Reference Plane(s)’ and
(ii) the strengths of all ‘Child Restraint Anchorages’ and
anchor fittings meet certain minimum requirements.
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
‘Child Restraint’ anchorage tests, where the ‘Child
Restraint Anchorage(s)’ are mounted on the seat or are
located on the vehicle body structure more than 100 mm
below a horizontal plane tangential to the point on the top
of the seat-back longitudinally ‘Forward’ of the ‘Child
Restraint Anchorage’. 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 ‘Child Restraint
Anchorages’ in vehicles subject to the ADR.
All load testing must be conducted on a representative
body shell or section thereof large enough to ensure that
Issue 2:
CIRCULAR 34/01-9-1
during testing any body distortion due to ‘Child Restraint
Anchorage’ loads are contained within such section.
However, fittings for loading the anchorages other than
the ‘Child Restraint Anchor Fitting’, may be replaced by
stronger or stiffer representative items for the test.
If the tests involve seats because the ‘Child Restraint’ is
located in the vehicle body structure more than 100 mm
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 (if applicable) and ‘Child
Restraint Anchorages’ and ‘Child Restraint Anchor
Fittings’ shall be structurally representative of the design
condition as reflected in the production drawings.
Further, if dynamic testing is employed, 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
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 with rear seats is 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.
5 EQUIPMENT
5.1 Static Tests
5.1.1 Basic Equipment
5.1.1.1 The test rig or rigs shall be capable of rigidly
securing a vehicle body (or whole section thereof) and
providing mounting points for one or more static load
applicators as determined by the configuration of the
‘Child Restraint Anchorages’.
5.1.1.2 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
Page 5 of 15
CIRCULAR 34/01-9-1
CIRCULAR 34/01-9-1
TEST PROCEDURE
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 that the
load is held for at least 1 second.
5.1.3.3 Order of Accuracy. Except where specified
in the ADR or referred documents, the following order
of accuracy is considered to be commercially
achievable and should be taken as a guide.
Instrumentation of lesser accuracy is acceptable,
however, in all cases the measurement uncertainty
must be taken into account in determining the 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 conducted with the load
reading at least the specified load plus maximum
instrument error. A typical instrument system for load
measurement would have an order of accuracy of 5%.
Deflection measurements should be made within 3
mm.
5.1.3.4 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.
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 ‘Child Restraint Anchorages’. Note that
for all tests the associated seat or seat back must also
be installed in the body.
5.1.1.3 Adjustable, Static Load Application.
Typically this comprises three hydraulic cylinders
which can be adjusted in position to apply loads in
longitudinal vertical planes of at least:3.4 kN for each ‘Child Restraint Anchorage’ in
the direction given by the ‘Design line of action’.
See Section 6.1.2
5.1.1.4 Where ‘Child Restraint Anchorages’ are
mounted on seats, (or in the case of ‘Child Restraint
Anchorage’s being located in the vehicle body
structure more than 100 mm below a horizontal plane
tangential to the top point of rear seat back) sufficient
additional load applicators are required to provide
simultaneously the child restraint loads and ADR 3/01
- ‘Seat Anchorages’ loads - refer to Circular 3/01-9-1.
5.1.2 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 ‘Child Restraint 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 all actuators and 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.
5.1.3 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 more than one actuator is
required,
instrumentation
with
multi-channel
recording is usually required to provide the necessary
indication of loads.
5.1.3.1 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.
5.1.3.2 Recording. Where automatic recording is
used, multi-channel light beam or pen recorders are
suitable as they allow immediate reading to ensure that
the required loads are achieved simultaneously in all
CIRCULAR 34/01-9-1
5.2 Dynamic Tests
5.2.1 Basic Equipment.
5.2.1.1 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 34.7.3.4)
• 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 at least
20 ms except for periods of less than 1 ms.(Clause
34.7.3.5)
Page 6 of 15
5.2.1.2 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 are described by the
drawings produced by the TNO (Research Institute for
Road Vehicles) Netherlands for a 50th percentile 6
year old child.
5.2.1.3 Fixtures. For dynamic testing the only
Issue 2:
TEST PROCEDURE
fixtures required are those to allow the body shell (or
part thereof) to be mounted to the sled to achieve a
deceleration while travelling ‘Forward’. These must
be as rigid as feasible to reduce structural “ringing”.
5.2.2 Instrumentation.
Sufficient equipment is
needed to ensure that the required velocity and
deceleration levels have been achieved.
5.2.2.1 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 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.
5.2.2.2 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.
5.2.2.3 Order of Accuracy. Timing lines should be
within 1% accuracy. Total deceleration and velocity
measurement system accuracies 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 require system calibration against a
known standard prior to each test, 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.
5.2.2.5 Calibration of test rig
See Section 6.2.2.2.
6 PROCEDURES
6.1 Location Check
6.1.1 (Clause 34.1.7). Determine the ‘Design Line of
Action’ in side view by drawing a line from the ‘Child
Issue 2:

CIRCULAR 34/01-9-1
Restraint Anchor Fitting’ ‘Interface Profile’ located in
the manufacturer’s nominated design position to the
Shoulder Point reference of the 2-dimensional
‘Manikin’.
(Refer Annex A - Test Equipment
Diagrams).
6.1.2 (Clause 34.7.2.1). 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. Where the ‘Design
Line of Action’ is determined by the seat back and the
‘Child Restraint Anchor Fitting’ is located more than
100 mm below a horizontal plane tangential to the
point on the top of the seat back longitudinally
‘Forward’ of the ‘Child Restraint Anchor Fitting’,
then the direction of test load shall be not more than
5 degrees above or below the horizontal and not more
than 5 degrees to the left or right of the longitudinal
axis of the vehicle.
6.1.3 (Clause 34.3). For LEP and MA category
vehicles determine that one ‘Child Restraint
Anchorage’ is provided for each adult ‘Seating
Reference Plane’ in the ‘Second Row Seats’ except
where the seat back is divided for individual folding
into two or more sections and a division lies
substantially on the ‘Seating Reference Plane’ of the
middle seating position then a ‘Child Restraint
Anchorage’ need not be provided for that seating
position.
For MB, MC and MD1 Category vehicles 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. 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 or for ‘Folding Seats’
where a ‘Child Restraint’ would bar access to the rear
seats a ‘Child Restraint Anchorage’ need not be
provided for that seating position (Clause 34.3.2.2)
6.1.4 (Clause 34.4.1.2). Ensure that the anchorage
incorporates an internal thread of 5/16 inch - 18 UNC
- 2A.
6.1.5 (Clause 34.4.1.3). Ensure that no items need to
be removed to gain access to the anchorage except
closure plugs and items removable with the use of
simple hand tools.
6.1.6 (Clause 34.2.2). Ensure that the vehicle
handbook or other data supplied with the vehicle
includes:(a)The warning specified in Clause 34.2.2.1.
(b)Details of the thickness (and number) of ‘spacers’
required at each ‘Child Restraint Anchorage’ (as
applicable), location and correct method of
installation and orientation of ‘Child Restraint Anchor
Fitting(s)’ ,(as applicable) and method of attachment

CIRCULAR 34/01-9-1
TEST PROCEDURE
and orientation relative to the front of the vehicle of
‘Attaching Clip(s)’.
(c)Details of the dedicated anchor fitting package in
according to Clause 34.2.1.2.1 (if applicable).
6.1.7 (Clause 34.5.3). Check that each ‘Child
Restraint Anchorage’ lies within 40 mm of the
corresponding ‘Seating Reference Plane’.
6.1.8 (Clause 34.5.1). Check that anchorages and
fittings are located within the vehicle in a part of the
body structure which would not normally be movable,
or if movable would not cause the ‘Upper Anchorage
Strap’ to be stretched when moved.
6.1.9 (Clause 34.5.2).
Check that each ‘Child
Restraint Anchor Fitting’ ‘Interface Profile’ is located
within the shaded area shown in Annex B (a) for each
applicable seating position.
6.1.10 (Clause 34.4.1.1). Check that the location of
the anchorages provides clearance for installation of
the ‘Child Restraint Anchor Fitting’, ‘Spacer(s)’ and
attaching hardware. Refer Annex B(b) .
6.1.11 (Clause 34.6). Check that sufficient clearance
exists around each ‘Child Restraint Anchor Fitting’ to
allow latching and unlatching, without the use of tools,
of the ‘Attaching Clip’ to the ‘Child Restraint Anchor
Fitting’ when it is installed in the vehicle. Refer
Annex B(c) .
6.1.12 (Clause 34.2.3). Check that the ‘Child
Restraint Anchor Fitting’ has been designed to avoid
the possibility of inadvertent disengagement from a
typical ‘Attaching Clip’ when the ‘Child Restraint
Anchor Fitting’ is mounted as shown in Annex C of
this circular.
6.1.12.1 To test for this requirement bolt the ‘Child
Restraint Anchor Fitting’ to a flat steel surface as in
Annex C , but without any spacers and with the
‘Attaching Clip’ fully engaged into the anchor fitting.
The ‘Attaching Clip’ shall not be capable of being
disengaged from the ‘Child Restraint Anchor Fitting’
without deliberate action by depressing the retention
device on the ‘Attaching Clip’ with the fingers.
6.1.12.2
To determine compliance with this
requirement the following referenced ‘Attaching
Clips’ shall be used:(1)a 10025 attaching clip manufactured by Nexus
USA (Fastex Australia); and
(2)an attaching clip, assembly No. FO 8954 using
part No. 14585 clip manufactured by Indiana
Mills Manufacturing Inc. USA.
6.2 Strength Test Method (Clause 34.7).
Compliance may be demonstrated using static test
methods detailed in Section 6.2.1 or dynamic test
methods as outlined in Section 6.2.2.
CIRCULAR 34/01-9-1
Page 8 of 15
6.2.1 Static Test - (Clause 34.7.2).
6.2.1.1 Preparation of Test. Ensure that the rear
seat(s) is installed in the body and confirm that the
mounting arrangements for the seat(s) and ‘Child
Restraint Anchorage’s are in accordance with the
vehicle layout and that production fixings at minimum
production torque are used.
Ensure that sufficient body structure is incorporated in
the test set up and that it is mounted to the test rig at or
adjacent to the suspension mounting point or other
substantial body member.
Ensure that the load actuators are installed to apply
equal, simultaneous loads to all ‘Child Restraint
Anchorage’s in the vehicle and that each actuator acts
along the correct direction of the Test Load as detailed
in Section 6.1 and shown in Annex A.
Review the instrumentation to ensure that all scales
and zeros are correctly set. Carry out any feasible
‘in-situ’ calibration.
Review load settings. Where several loads are applied
automatically and simultaneously, check settings by
artificially locking the load actuators and ensure that
each net load setting is a minimum of 3.4 kN.
Ensure that the load actuators are connected to the
anchorages using flexible, but axially stiff straps several strands of seat belt webbing is often used.
6.2.1.2 Test. Operate the test rig and ensure that all
required net loads are applied for a minimum of 1
second. See Section 7 for analysis of results. Repeat
Sections 6.1.1 and 6.1.2 for each condition determined
for the test program.
6.2.1.3 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.
6.2.1.4 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 Dynamic Test. (Clause 34.7.3)
6.2.2.1 Preparation for Test. Arrange the body (or
part thereof) on the rig so that it is decelerated while
moving forward.
Confirm that the mounting
arrangements of the rear seat assembly (or assemblies)
are in accordance with the vehicle layout, that the
production fixings at minimum production torque
settings are used and that sufficient body structure in
the area of the mountings is included in the test setup.
Ensure that one test dummy is installed as near as
practical to each rear ‘Seating Reference Plane’ and
that each is restrained using a suitable restraint
Issue 2:
TEST PROCEDURE
comprising load bearing material having an elongation
of not more than 25% when subjected to a load of
11 kN (Clause 34.7.3.2). Each pelvic restraint
position is to be attached to the corresponding adult
lap anchorage and each upper torso restraint position
is to be attached to the ‘Child Restraint Anchorage’.
6.2.2.2 Rig Calibration. (Clause 34.7.3.5) Remove
the test dummies and attach a mass of 21.4 kg times
the number of rear seating positions rigidly to the rig.
Ensure that the mass of the resulting moving rig is at
least 380 kg plus the mass representing the removed
dummies.
Operate the test rig and make adjustments if necessary
to achieve the following velocity-time profile after
allowing for instrument measurement uncertainty:• Minimum velocity change 49 km/h.
2
• Within 30 ms a deceleration of between 235 m/s
2
(24.0 g) and 335 m/s (34.1 g) is achieved.
• The deceleration is maintained within these limits
for not less than 20 ms, except for periods of less
than 1 ms.
6.2.2.3 Test.
(Clause 34.7.3.6).
Remove the
calibration masses and re-install the dummies,
ensuring that the restraint system is adjusted to
eliminate slack.
Operate the test rig and determine the results as in
Section 6.2.2.4.
6.2.2.4
Determination
of
Results.
The
deceleration-time profile and gate transit time(s) are
read from the recorder charts and any deceleration
peak of less than 3 ms duration disregarded if due to
ringing. This should be done as soon as possible after
the tests, together with a check that instrument
calibrations have not changed. Any charts etc are to
be retained as original data. Velocity change is
determined by calculation given the length of the
speed gate(s).
6.2.2.5 Reporting Results. For each test an internal
report giving a complete description of the material
tested, equipment used, results and order of accuracy
is to be prepared. For submission to the Administrator
the determined results for deceleration and time are to
be recorded together with the internal report number in
the appropriate section of the Summary of Evidence
Report - see Section 8.
7 ANALYSIS OF RESULTS
The anchorage systems are deemed to have conformed to
ADR 34/01 if the load, deceleration, dimensional and
functional requirements of Section 6.2. have been met
CIRCULAR 34/01-9-1
without separation of the anchorage from its adjacent
body work and without general structural failure of the
body shell.
8 SUMMARY OF EVIDENCE REPORT
