10 Evaluation of the Drying Time Test
-
Return the tool carrier to the start position.
-
Swivel the tool holders (incl. tools) to the left into
idle position.
-
Cut the woollen thread of test tools no. 1 and 2.
-
Lock test tool no. 3.
-
Remove the glass strips with the test coatings
-
Place a centimeter rule in such a way that the zero point
is located at the start position of the test coating and
determine the "measuring point". Measure the distance
in cm and multiply it by the preset drying time speed.
1
v
Drying time speed
v' =
Drying time
Units:
t = s x v'
[ s] = cm
[ t] = min
[ v'] =
min
cm
The "measuring point" for the different test tools is defined hereafter:
Test Tool No. 1:
Remove the woollen thread carefully from
the end of the strip; the point at which the
thread cannot be removed from the film is
the "measuring point" for dust drying.
Test Tool No. 2:
Proceed as under Tool No. 1.
The "measuring point" is the lack of stickiness
point.
Test Tool No. 3:
Carefully brush the glass pearls from the film
using a soft hair brush. The point at which they
stick is the "measuring point" for the dust
drying.
Test Tool No. 4:
The end of the indentation track which is
produced by this tool is the "measuring point"
for the grip dryness.
Test Tool No. 5:
The end of the track produced by this tool is
the "measuring point" for the through dryness.

Test Tool No. 6:
This tool provides several "measuring points":
(see figures next page)
Beginning of the track = End of levelling
Track is rhomb shaped = Beginning surface
drying
Track is linear
= Beginning of
through hardening
Track is interrupted
= Start of lack of
stickiness
Test Tool No. 7:
The end of the impression track is the
"measuring point" for the dryness.

11.1 Preparation of the basic instrument
• Place glass plate (1).
• Fix crosshead (2) (= attachment assembly) with the knurled
screws so that the free leg with the longitudinal slot points upwards
to the right.
11.2 Set-up of the Mounting Adapter (9)
• Slide the pins of the aluminium block from the left through the
longitudinal slot of the crosshead (long pin pointing forwards, short
pin pointing backwards).
• Place plastic plate on the protruding pin (narrow edge upwards).
• Place swivel plate: Guide threaded pin through the plastic plate,
the crosshead and the aluminium block.
• Connect all parts with the thumb screw (3).
• Fix the assembled mounting adapter (9) for the test instrument
with the thumb screw (3) approximately in the centre of the
crosshead (the test should be performed in a range of ± 50 mm
around the centre line of the basic instrument).

11.3 Inserting the Test Instrument (Model 318 / Model 435)
• Unscrew the head of the test instrument (if necessary, relieve the
spring stretched before).
• Loosen the thumb screw (3) of the mounting adapter and turn the
swivel plate so that the bore of the clamping part (10) for the test
instrument lies almost horizontally.
• Loosen locking screw (6) (Allan key SW 3 is included in the scope
of supply).
• Slide the test instrument from behind through the boring of the
clamping part (10) and insert the spring for the pressure range
required (colour code blue/red/yellow for pressure range 3/10/20 N).
• Screw the head onto the test instrument:
Hardness Test Pencil, Model 318 (7)
− The used test pencil has to be attached with the special head
included in the delivery specification of the attachment for scratch
hardness tests.
− The special head is 2 mm smaller than that of the standard version
so that the tip of the stylus point juts out by 3 mm instead of 1 mm.
− Select stylus point before screwing down the head:
ISO/Bosch/van Laar geometry with spherical tip 1/0.75/0.5 mm dia.
(Ord.-Nos 0428.03.32/0428.02.32/0428.04.32)
Mar Tester, Model 435
− Remove rotating guide rolls.
− Select marking disc before screwing down the head:
Test discs made of Duroplast/copper/steel 16 mm dia, / R 0.5 mm
(Ord.-Nos 0430.01.31/0430.02.32/0430.03.32)
− Change test disc as follows (Allan key SW 2 required is included in
the scope of supply):
Unscrew countersunk screw over the thread and remove it
together with the rosette - pull out the test insert - unscrew the
locking screw of the test disc - change test disc and assemble the
head in reverse order.
• Place test panel or any calibration plate (8) of same thickness on
the glass plate (1) in the area of the test instrument.
• Adjust a light spring pressure on the test instrument and turn the
swivel plate up to the limit stop at the long pin.
• Place the adapter for elevation adjustment (11) onto the test panel
or calibration plate and adjust the height of the test instrument so
that its head touches the surface of the adapter (11). Thereby the
test tip/test disc must be pluged into the short/long slot of the
adapter.
• When adjusting Model 435 make sure that the test disc can be set
across and parallel to the test direction.

• Tighten the locking screw of the swivel plate and take off the
adapter for elevation adjustment (11).
• Incline the test instrument by turning the swivel plate in such a way
that the test tip/test disc does no longer touch the surface of the
test panel or calibration plate. Then tighten the thumb screw (3).
• The test instrument is now swung out and ready for work.
11.4 Adjusting the Basic Instrument
• After having switched on the instrument and having performed the
basic reset select the modes "FAST" (high working speed range
indicated in mm/s) and "Ö" (working direction from left to right).
• Press key POS and shift the start position so far to the right that
the working path is as long as the desired scratch length.
• Store start position (press key POS).
• Select speed and store (key SPEED).
11.5 Preparing the Test
• Position the test panel (11) on the glass plate (1) and fix it with
adhesive tape in such a way that the scratching takes place on the
test panel in the area provided for the test.
• Loosen the thumb screw (3) on the mounting adapter (9). Turn
swivel plate up to the limit stop and then retighten the thumb screw
(the test instrument is now in perpendicular and swung-in
position).
• Set the required pressure; then tighten the knurled screw (4) (for
pressures exceeding 10 N use the spring steel sheet as "screw
driver").
11.6 Test Performance
• Start the movement of the crosshead (key START).
• After the scratching operation bring the instrument back into the
swung-out position.
• Return the crosshead (2) in the start position (key RESET).
• Replace the test instrument in the swung-in position while
adjusting the mounting block (9) laterally to get a new test track.
• Now a new test with the same parameters or a comparative test
with different pressure or speed can be started.

Care and Maintenance
12.1
Inspection and Maintenance
Generally the COATMASTER 510 does not require any
maintenance.
After finishing the film application, take off the film applicators and
clean them immediately.
Remove the paint collection trough and the working plate for
cleaning.
Once a year remove cover plate from the instrument (by loosening
the screws) and smear the two guide rods with an oiled cloth.
CAUTION:
Make sure that no oil drops onto the electronics.
The film applicators as well as the drying test tools are subject to
some natural wear and must be inspected from time to time to
ensure that they are in fault-free condition.
