6.1. All glazing materials, including glazing material for the manufacture of windscreens, shall
be such that, in the event of shattering, the danger of bodily injury is reduced as far as
possible. The glazing material shall be sufficiently resistant to the incidents likely to occur
in normal traffic, and to atmospheric and temperature conditions, chemical action,
combustion and abrasion.
6.2. Safety glazing materials shall in addition be sufficiently transparent, shall not cause any
noticeable distortions of objects as seen through the windscreen, and shall not give rise to
any confusion between the colours used in road-traffic signs and signals. In the event of
the windscreen's shattering, the driver shall still be able to see the road clearly enough to
be able to brake and stop his vehicle safely.

8. TESTS
8.1. The following tests are prescribed in this Regulation:
8.1.1. Fragmentation Test
The purpose of this test is:
8.1.1.1. To verify that the fragments and splinters produced by fracture of the glass pane are such
as to minimize the risk of injury, and
8.1.1.2. In the case of windscreens, to check residual visibility after shattering.
8.1.2. Mechanical Strength Test
8.1.2.1. Ball-impact Test
There are two forms of tests, one using a 227g ball and one using a 2,260g ball.
8.1.2.1.1. 227g ball test: The purpose of this test is to assess the adhesion of the interlayer of
laminated glass and the mechanical strength of uniformly-toughened glass and plastic
glazings.
8.1.2.1.2. 2,260g ball test: The purpose of this test is to assess ball-penetration resistance of
laminated glass.
8.1.2.2. Headform Test
The purpose of this test is to verify the compliance of glazing with the requirements
relating to the limitation of injury in the event of impact of the head against the windscreen,
laminated glass and glazing of glass-plastic and rigid plastic other than windscreens,
together with the multiple-glazed units used in the side windows.
8.1.3. Test of Resistance to the Environment
8.1.3.1. Test of Resistance to Abrasion
The purpose of this test is to determine whether the resistance of a safety glazing to
abrasion exceeds a specified value.
8.1.3.2. Test of Resistance to High Temperature
The purpose of this test is to verify that no bubbles or other defects occur in the interlayer
in laminated glass or glass-plastics glazing when exposed to high temperatures over an
extended period of time.
8.1.3.3. Resistance-to-radiation Test
The purpose of this test is to determine whether the light transmittance of laminated-glass
panes, glass-plastics glazing or glass glazing faced with plastics material when exposed to
radiation over an extended period of time is significantly reduced thereby or whether the
glazing is significantly discoloured.

8.2. Tests Prescribed
8.2.1. Safety glazing materials shall be subjected to the tests listed in the following tables:
8.2.1.1. and 8.2.1.2.
8.2.1.1. Safety glazing shall be subjected to the tests listed in the following table:

9. MODIFICATION OR EXTENSION OF APPROVAL OF A TYPE OF SAFETY GLAZING
MATERIAL
9.1. Every modification of a type of safety glazing material, or in the case of windscreens every
addition of a windscreen to a group, shall be notified to the Type Approval Authority which
approved the type of safety glazing material. The department may then either:
9.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect
and, in the case of windscreens, that the new type comes within the approved group of
windscreens, and that in any case the safety glazing material still complies with the
requirements; or
9.1.2. Require a further test report from the technical service responsible for conducting the
tests.
9.2. Communication
9.2.1. Confirmation or refusal of approval (or extension of approval) shall be communicated by
the procedure specified in Paragraph 5.3. above to the Parties to the Agreement applying
this Regulation.
9.2.2. The competent authority which has granted an extension of approval shall enter a serial
number on each communication of extension.
10. CONFORMITY OF PRODUCTION

3.2.2. Adjustment and Calibration
To perform the headform test the phantom head is fixed to the cross arm of the guide
system (Figure 2.2) and moved to the required drop height by means of a lifting device.
During the headform test the cross arm with the phantom head is released. After passing
the height adjustable light barrier the phantom head is released from the cross arm, the
cross arm's fall is dampened and the phantom head falls onto the sample.
No impulse may be given to the phantom head by the drop appliance or by the measuring
cable, so that it is accelerated only by gravity and falls vertically.
Figure 2.2
Test Apparatus for the Headform Experiment with Deceleration Measurement

3.2.5. Tests on complete glazing (used for a drop height between 1.5m and 3m). Place the glazing
freely on a support with an interposed strip of rubber of hardness 70 IRHD and thickness of
about 3mm.
3.2.6. Evaluation
The glazing shall be clamped to the supporting structure by means of appropriate devices.
The surface of the glazing shall be substantially perpendicular to the incident direction of the
headform weight. The headform weight shall strike the glazing at a point within 40mm of its
geometric centre on that face which represents the inward face of the plastic glazing when
the latter is mounted on the vehicle, and shall be allowed to make only one impact.
Starting from a selected initial drop height, the drop heights should be raised by 0.5m
respectively in each further experiment. The deceleration curves occurring on impact on the
sample for a , a and a should be recorded according to time t.
After the headform test, it should be checked whether a glazing edge has moved more than
2mm in the mount and whether the requirement for the point of impact was met. The
acceleration components a and a should be smaller for vertical impact than 0.1 a .
The deceleration curves should be evaluated as follows:
The resulting deceleration a (t) in the centre of gravity according to equation (1) from the
measured deceleration curves a (t), a (t) and a (t) is to be compounded as multiples of the
acceleration due to gravity.
( )
(1) a () t = a () t + a () t + a () t
The time for which a deceleration of 80g with a is continually exceeded and the greatest
deceleration of a should be determined. The HIC-value should be calculated as a
measurement of the danger of blunt skull-brain-injuries using the following equation (2):


= ⎜


(2) HIC ( t − t ) a ( t)dt




The integral limits t and t should be selected in such a way that the integral takes a
maximal value.

4.1.1. Abrading instrument shown diagrammatically in Figure 4 and consisting of:
A horizontal turntable, with centre clamp, which revolves counter-clockwise at 65 to
75 rev/min.;

4.1.4. Optical system consisting of a lens with a focal length f of at least 500mm and corrected for
chromatic aberrations. The full aperture of the lens shall not exceed f/20. The distance
between the lens and the light source shall be adjusted in order to obtain a light beam which
is substantially parallel. A diaphragm shall be inserted to limit the diameter of the light beam
to 7mm ± 1mm. This diaphragm shall be situated at a distance of 100mm ± 50mm from the
lens on the side remote from the light source.

with an integrating sphere 200mm to 250mm in diameter. The sphere shall be equipped with
entrance and exit ports for the light. The entrance port shall be circular and have a diameter
at least twice that of the light beam. The exit port of the sphere shall be provided with either
a light trap or a reflectance standard, according to the procedure described in
Paragraph 4.4.3. below. The light trap shall absorb all the light when no test piece is
inserted in the light beam.
The axis of the light beam shall pass through the centre of the entrance and exit ports. The
Diameter b of the light-exit port shall be equal to 2 a.tan 4°, where a. is the diameter of the
sphere. The photoelectric cell shall be mounted in such a way that it cannot be reached by
light coming directly from the entrance port or from the reflectance standard.
The surfaces of the interior of the integrating sphere and the reflectance standard shall be of
substantially equal reflectance and shall be matt and non-selective.
The output of the photoelectric cell shall be linear within ±2% over the range of luminous
intensities used. The design of the instrument shall be such that there is no galvanometer
deflection when the sphere is dark.
The whole apparatus shall be checked at regular intervals by means of calibration standards
of defined haze.
If haze measurements are made using equipment or methods differing from those defined

unabraded area in accordance with the formula above. Average the results for each test
piece. In lieu of the four measurements, an average value may be obtained by rotating the
piece uniformly at 3 rev/sec or more.
For each type of safety glazing, carry out three tests with the same load. Use the haze as a
measure of the subsurface abrasion, after the test piece has been subjected to the abrasion
test.
Measure the light scattered by the abraded track at a minimum of four equally-spaced points
along the track in accordance with the formula above. Average the results for each test
piece. In lieu of the four measurements, an average value may be obtained by rotating the
piece uniformly at 3 rev/sec or more.
4.5. The abrasion test will be carried out only at the discretion of the laboratory conducting the
test with due regard to the information already at its disposal.
Except for glass-plastics materials, changes in the interlayer or materials thickness will not
normally necessitate further testing.

4.9. Wiper Laboratory Test
4.9.1. Apparatus
Determination of whether a rigid plastic material intended to be used as safety glazing in
locations requisite for driver visibility and additionally equipped with a system suitable to
wipe the surface has a certain minimum resistance against the action of a wiper including
dirt at ambient temperature.
The apparatus is shown schematically in the following figures and includes at least the
following individual components:
4.9.1.1. A base apparatus with two pillars providing a back and forth linear motion with 37 ± 2 cycles
per minute and the possibility to adjust the stroke length (half a wipe cycles) to 130 ± 5mm,
which leads to an average wipe speed of 160 ± 15mm/s (speed range from 0 (reversal
point) to maximal speed (between the two reversal points)),
4.9.1.2. A wiper carriage assembly (see 1 in Figures 11 and 12) having a beam which spans across
the width of the base apparatus and can be mounted at its ends to the pillars, furthermore
this carriage assembly has two self-supporting arms (see 2 in Figures 11 and 12) where a
wiper holder can be attached (the distance between the sample surface and bearing of
self-supporting arm at the carriage assembly is 100 to 105mm),
4.9.1.3. A wiper holder (see 3 in Figure 11) suitable to attach a normal wiper blade (see 4 in
Figure 11) and adjusted to provide a load of 15 ± 0.5g/cm (the weight of the wiper blade and
its holder together with the wiper blade width determine the wiper load in g/cm),
4.9.1.4. Two sample boxes (see 5 in Figures 11 and 12) made out of inert, material in the interior
dimension of 200mm × 120mm (50mm height) used to be filled with the aqueous
suspension and having a hole at the bottom where the test sample can be inserted and
therefore used as a test sample holder,
4.9.1.5. Different spacer plaques (see 7 in Figure 11) (e.g. made out of the sample box material) in
the dimension of the sample but with different thicknesses used to compensate different test
sample thicknesses (it is necessary that the bottom surface of the sample box and the
sample surface to be tested are on the same height); furthermore care has to be taken to
avoid scratching the test sample placed on top of the spacer (e.g. by placing a ultrathin soft
film on the surface of the spacer),

Figure 12
Bird's-eye View of the Apparatus
4.9.2. Wiper Blade
The wiper used to test the resistance of rigid plastic safety glazing against wiping with dirt
shall be either:
(a)
(b)
A normal glass windscreen wiper blade based on chloroprene type rubber
(CR grade), chlorinated and with a graphite based anti-friction coating on the
surface in a width of 80mm or,
A commercially available specific device which is adjusted to the surface
characteristics of the rigid plastic glazing and actually intended to be used in the
vehicle (e.g. a hydrophobic wiper blade) also in a width of 80mm. The geometric and
chemical characteristics and type of the specific device used for the type approval
test shall be described in the test report.
In case the specific device has a significantly different cross profile it might be necessary to
adapt the wiper blade holder respectively.
A new blade shall be used for every test sample. The wiper blade shall be fixed into the
holder as shown below.

4.9.4. Aqueous Suspension
The aqueous suspension shall contain:
(a)
195 ± 1g water (with a hardness of less than 205mg/l after evaporation) (97.5wt.%)
(b) 5 ± 0.2g so called ISO test dust A4 (according to ISO 12103-1) (2.5wt.%)
(c)
And shall be freshly prepared at room temperature and stirred before use. This
amount of aqueous suspension is sufficient for testing one sample and leads to a
filling level of around 10mm in the sample box. A new aqueous suspension shall be
used for every test.
4.9.5. Procedure
4.9.5.1. Sample Pre-treatment
Before testing the samples shall be cleaned using a soft cloth soaked with isopropanol
followed by deionized water and drying. After cleaning the samples shall be conditioned for
at least 24h at 23°C ± 2°C and (50 ± 5)% relative humidity.
The initial haze value according to Annex 3, Paragraph 4.4.3. of this Regulation of the test
sample is measured at 9 measurement points across the sample (see 4 in Figure 16).
4.9.5.2. Test Equipment Pre-check
4.9.5.2.1. Before the equipment is used for testing samples the back and forth linear motion of the
pillars of the base apparatus shall be checked for being uniform without any disturbance like
getting stuck or starting to vibrate.
4.9.5.2.2. Build up the whole instrument including tray, wiper carriage assembly, wiper blade holders
and new wiper blades but without sample box and sample (see Figure 14). To do so the two
new wiper blades shall be mounted to their respective wiper blade holders and the latter
ones shall be fixed to the carriage assembly. Then align using a spirit level the base plate
where later the sample box will be placed and the wiper carriage assembly. Check that the
distances of the two bearings of both self-supporting arms at the wiper carriage assembly
and at the wiper blade holder are identical. Furthermore control visually that the wiper blade
rest on the base plate uniformly without losing contact to the base plate at any point of the
wiper blade.

4.9.5.3.2. The sample box shall be placed into the stainless steel tray and fixed using adhesive tape
on the two short sides of the box according to Figure B. It is essential that the position of the
box leads to a wiping area in exactly the middle of the sample (see 2 in Figure 16). A spacer
plaque adjusted to the thickness of the test sample so that the test sample surface and the
bottom surface of the sample box are on the same height (no visible gap in height between
sample and bottom surface of the sample box) shall be placed into the hole in the bottom of
the sample box.
4.9.5.3.3. The sample shall be placed with the to be tested side facing up (representing the outside
surface of the plastic glazing part) into the sample holder of the sample box onto the right
spacer plaque (which has a soft masking film on its surface to avoid scratching the test
samples backside). An adhesive tape shall be used all around the test sample to fix it into
the holder and seal the space between sample edge and sample box (to avoid suspension
penetrating underneath the sample). The tape shall be used in such a way that the overlay
between tape and sample is at maximum 10mm or in other words in such a way that the
wiping area of the sample (see Figure 16) is free of any adhesive tape.
4.9.5.3.4. After fixing the sample the carriage assembly including wiper holders and blades from the
pre-check shall be mounted to the pillars of the base apparatus. Thereby, the wiper blades
get into contact with their respective samples. The correct load (15 ± 0.5g/cm) of the wiper
blade onto the sample shall be checked using a spring balance. Ensure again that the
whole equipment (especially test sample, box, and carriage assembly inclusive wiper holder
and blade) is aligned by using a spirit level.
4.9.5.3.5. A freshly prepared suspension shall be filled into each sample box and then the linear back
and forth motion of the wiper blade shall be started.
4.9.5.3.6. In order to ensure a homogenous abrading it is necessary to follow the action described
below:
4.9.5.3.6.1. After half of the test cycle numbers 10,000 cycles the test shall be stopped and the two
sample boxes shall be exchanged without turning them (see Figure 15); this leads to an
exchange for the two simultaneously tested samples regarding their wiper blades and
furthermore alters the alignment of the self-supporting arm carrying the blade (from left to
right or the other way round).

4.9.5.4.4. Nine measurement points according to Figure 16 below shall be used to determine the delta
haze at these points and calculate an average delta haze afterwards.
Key
1 Sample (150mm × 100mm)
2 Wiping area on the sample (130mm × 80mm)
3 Measurement area on the sample (75mm × 60mm)

measurement points the average delta haze (including standard deviation) resulting from
abrasion action of aqueous dirt wiped for 20,000 cycles on the sample surface by a to be
reported wiper blade type.

6.1.1.2. Power-supply transformer and capacitor capable of supplying to the lamp
(Paragraph 6.1.1.1.) a starting peak voltage of 1,100V minimum and an operating voltage of
500V ± 50V.
6.1.1.3. Device for mounting and rotating the test pieces at 1 to 5 rev/min about the centrally-located

6.1.2. Test Pieces
6.1.2.1. The size of the test pieces shall be 76mm × 300mm.
6.1.2.2. The test pieces shall be cut by the laboratory from the upper part of the glazing in such a
way that:
6.1.3. Procedure
In the case of glass panes, the upper edge of the test piece coincides with the upper edge
of the glass pane.
In the case of windscreens, the upper edge of the test piece coincides with the upper limit of
the zone in which regular transmittance shall be measured, determined in accordance with
Paragraph 9.1.2.2. of this Annex.
Check the regular light transmittance, determined according to Paragraphs 9.1.1. to 9.1.2. of
this Annex, of three test pieces before exposure. Protect a portion of each test piece from
the radiation, and then place the test pieces in the test apparatus 230mm from and parallel
lengthwise to the lamp axis. Maintain the temperature of the test pieces at 45°C ± 5°C
throughout the test.
That face of each test piece which would constitute a glazed exterior part of the vehicle shall
face the lamp. For the type of lamp specified in Paragraph 6.1.1.1. the exposure time shall
be 100h. After exposure, measure the regular light transmittance again in the exposed area
of each test piece.
6.1.4. Each test piece or sample (total number 3 pieces) shall be subjected, in accordance with the
procedure above, to radiation such that the radiation on each point of the test piece or
sample produces on the interlayer used the same effect as that which would be produced by
solar radiation of 1,400W/m for 100h.

The test pieces shall be prepared in such a way that:
(a)
(b)
At least one edge of the test pieces coincides with an original edge of the glass pane,
If several test pieces are tested at the same time, adequate spacing shall be provided
between them.
Precautions shall be taken to prevent condensate from the walls or ceiling of the test
chamber from falling on the test pieces.

7.3. Interpretation of Results
7.3.1. Safety glazing shall be deemed to be satisfactory from the point of view of resistance to
humidity if no significant change is observed more than 10mm from the uncut edges and
more than 15mm from the cut edges after ordinary and treated laminated glass glazing have
been maintained for two hours in the ambient atmosphere, and plastics-faced and
glass-plastics glazing have been maintained for 48h in the ambient atmosphere.
7.3.2. A set of test pieces or samples submitted for approval shall be considered satisfactory from
the point of view of the test for resistance to humidity if all the tests have given a satisfactory
result.
8. TEST OF RESISTANCE TO TEMPERATURE CHANGES
8.1. Test Method
Two test pieces 300 × 300mm shall be placed in an enclosure at a temperature of
-40°C ± 5°C for a period of 6h; they shall then be placed in the open air at a temperature of
23°C ± 2°C for one hour or until temperature equilibrium has been reached by the test
pieces. These shall then be placed in circulating air at a temperature of 72°C ± 2°C for
3h. After being placed again in the open air at 23°C ± 2°C and cooled to that temperature,
the test pieces shall be examined.

9.1.2. Procedure
The sensitivity of the measuring system shall be adjusted in such a way that the instrument
indicating the response of the receiver indicates 100 divisions when the test piece is not
inserted in the light path. When no light is falling on the receiver, the instrument shall read
zero.
Place the test piece at a distance from the receiver equal to approximately five times the
diameter of the receiver. Insert the safety-glass pane between the diaphragm and the
receiver and adjust its orientation in such a way that the angle of incidence of the light beam
is equal to 0 ± 5°. The regular transmittance shall be measured on the test piece, and for
every point measured the number of divisions, n, shown on the indicating instrument, shall
be read. The regular transmittance τ is equal to n/100.
9.1.2.1. In the case of windscreens, alternative test methods may be applied using either a test
piece cut from the flattest part of a windscreen or a specifically-prepared flat square with
material and thickness characteristics identical to those of the actual windscreen, the
measurements being taken normal (perpendicular) to the glass pane.
9.1.2.2. For the windscreens of M vehicles the test shall be carried out in Test Area B defined in
Annex 21, Paragraph 2.3., excluding any opaque obscuration impinging on it.
For the windscreens of N vehicles, the manufacturer may request that the same test may
be carried out either in Test Area B defined in Annex 18, Paragraph 2.3., excluding any
opaque obscuration impinging on it, or in the Zone I defined in Paragraph 9.2.5.2.3. of this
Annex.
For windscreens of other categories of vehicles, the test shall be carried out in the Zone I
defined in Paragraph 9.2.5.2.3. of this Annex.
However, for agricultural and forestry tractors and for construction-site vehicles for which it
is not possible to determine Zone I, the test shall be carried out in Zone I' as defined in
Paragraph 9.2.5.3. of this Annex.

10. BURNING BEHAVIOUR (FIRE-RESISTANCE) TEST
10.1. Purpose and Scope of Application
This method enables the horizontal burning rate of materials used in the passenger
compartment of motor vehicles (for example, private passenger cars, lorries (trucks), estate
cars, motor coaches) after exposure to a small flame to be determined.
This method permits testing of materials and components of a vehicle's interior equipment
individually or in combination up to a thickness of 13mm. It is used to judge the uniformity of
production lots of such materials with respect to their burning behaviour.
Because of the many differences between the real-world situation (application and
orientation within a vehicle, conditions of use, ignition source, etc.) and the precise test
conditions prescribed herein, this method cannot be considered as suitable for evaluation of
all true in-vehicle burning characteristics.

Figure 26

10.4.2. Sample holder, consisting of two U-shaped metal plates or frames of corrosion-proof
material. Dimensions are given in Figure 18.
10.4.3. Gas Burner
10.4.4. Test Gas
The lower plate is equipped with pins and the upper one with corresponding holes, in order
to ensure a consistent holding of the sample. The pins also serve as measuring points at the
beginning and end of the burning distance.
A support shall be provided in the form of heat-resistant wires 0.25mm in diameter spanning
the frame at 25-mm intervals over the bottom U-shaped frame (see Figure 19).
The plane of the lower side of samples shall be 178mm above the floor plate. The distance
of the front edge of the sample holder from the end of the chamber shall be 22mm; the
distance of the longitudinal sides of the sample holder from the sides of the chamber shall
be 50mm (all inside dimensions). (See Figures 15 and 16).
The small ignition source is provided by a Bunsen burner having an inside diameter of
9.5mm. It is so located in the test cabinet that the centre of its nozzle is 19mm below the
centre of the bottom edge of the open end of the sample (see Figure 16).
The gas supplied to the burner shall have a calorific value of about 38MJ/m (for example
natural gas).
10.4.5. Metal comb, at least 110mm in length, with seven or eight smooth rounded teeth per 25mm.

10.5.2. Sampling
At least five samples shall be taken from the material under test. In materials having burning
rates differing according to the direction of the material (this being established by
preliminary tests) the five (or more) samples shall be taken and be placed in the test
apparatus in such a way that the highest burning rate will be measured.
When the material is supplied in set widths, a length of at least 500mm covering the entire
width shall be cut. From the piece so cut, the samples shall be taken at not less than
100mm from the edge of the material and at points equidistant from each other.
Samples shall be taken in the same way from finished products when the shape of the
product so permits. If the thickness of the product is over 13mm it shall be reduced to 13mm
by a mechanical process applied to the side which does not face the passenger
compartment.
Composite materials (see Paragraph 10.2.2.) shall be tested as if they were homogeneous.
In the case of materials comprising superimposed layers of different composition which are
not composite materials, all the layers of material included within a depth of 13mm from the
surface facing towards the passenger compartment shall be tested individually.
10.5.3. Conditioning
10.6. Procedure
The samples shall be conditioned for at least 24h, but not more than 7 days, at a
temperature of 23°C ± 2°C and a relative humidity of 50% ± 5%, and shall be maintained
under these conditions until immediately prior to testing.
10.6.1. Place samples with napped or tufted surfaces on a flat surface, and comb twice against the
nap using the comb (Paragraph 10.4.5.).
10.6.2. So place the sample in the sample holder (Paragraph 10.4.2.) that the exposed side faces
downwards, towards the flame.
10.6.3. Adjust the gas flame to a height of 38mm using the mark in the chamber, the air intake of
the burner being closed. The flame shall burn for at least one minute, for stabilization,
before the first test is started.
10.6.4. Push the sample holder into the combustion chamber so that the end of the sample is
exposed to the flame, and after 15s cut off the gas flow.
10.6.5. Measurement of burning time starts at the moment when the foot of the flame passes the
first measuring point. Observe the flame propagation on the side (upper or lower) which
burns faster.
10.6.6. Measurement of burning time is completed when the flame has come to the last measuring
point or when the flame is extinguished before reaching that point. If the flame does not
reach the last measuring point, measure the burnt distance up to the point where the flame
was extinguished. Burnt distance is the part of the sample destroyed, on the surface or
inside, by burning.

11.2. Test Method
11.2.1. Immersion Test
Four samples 180mm × 25mm shall be tested for each test and each chemical specified in
Paragraph 11.1. above, using a new test piece for each test and each cleaning product.
Before each test, samples shall be cleaned according to the manufacturer’s instructions,
then conditioned for 48h at a temperature of 23°C ± 2°C and a relative humidity of
50% ± 5%. These conditions shall be maintained throughout the tests.
The samples shall be completely immersed in the test fluid and held for one minute, then
removed and immediately wiped dry with a clean absorbent cotton cloth.

11.2.3. Interpretation of Results
11.2.3.1. The test for resistance to chemical agents shall be considered to have given a satisfactory
result if the sample does not exhibit any softening, tackiness, crazing or apparent loss of
transparency.
11.2.3.2. A set of samples shall be considered satisfactory with regard to the test for resistance to
chemical agents if at least three of the four tests carried out with each chemical have given
a satisfactory result.
11.2.4. Test Procedure Under Load
11.2.4.1. The chemicals shall be applied to the side of the test piece which represents the outside
face of the windscreen or safety glazing pane when mounted on the vehicle while this side
is under tensile stress.
The sample shall be simply supported as a horizontal level arm between a fixed supporting
edge at one end in such a way that the entire width will rest on a cutting edge (fulcrum)
which is 51mm from the fixed end support. A load shall be suspended from the free end of
the test specimen at a distance of 102mm from the fulcrum as shown in Figure 21 below:

11.2.6.2. A set of samples shall be considered satisfactory with regard to the test for resistance to
chemical agents if one of the following conditions is met:
11.2.6.2.1. All the tests have given a satisfactory result;
11.2.6.2.2. One test having given an unsatisfactory result, a new series of tests carried out on a new
set of samples has given a satisfactory result.
12. FLEXIBILITY TEST AND FOLD TEST
12.1. Scope
With this test has to be found out whether a plastic is to be classed into the categories of
rigid or flexible plastics.
12.2. Test Method
From the material of the nominal thickness a rectangular flat sample 300mm long and
25mm wide is cut out and horizontally clamped into a clamping device in such a way that
275mm of the length of the sample freely extend over the holding device. This free end shall
be supported horizontally by an appropriate device until the test begins. Sixty seconds after
removal of this support the vertical deviation of the free end is indicated in mm. If this
deviation exceeds 50mm a 180° fold test is performed subsequently. The sample is folded
concisely, after that it is folded around a 0.5mm thick piece of sheet metal in such a way that
it tightly contacts it on both sides.
12.3. Test Conditions
– Temperature: 20°C ± 2°C
– Relative Humidity: 60% ± 5%

Figure 35
Tool with Six Blades
13.3. Test Method
Cut through the coating on to the subsurface a pattern with 6 cuts and perpendicular to this
another one so that a grid with 25 squares arises (grid-cut).
The cutting tool should be drawn steadily with a speed of 2cm/s to 5cm/s so that the cuts
reach the subsurface but do not penetrate too deeply.
The cutting is conducted in such a way that the two leading heads at the edge of the
apparatus touch the surface uniformly. After the test the cuts are examined with a
magnifying glass to check that they reach the subsurface. The test is carried out at least at
two different positions of the sample. After the cuts have been produced they are brushed
5 times with slight pressure in both diagonal directions with a hand brush with polyamide
bristles.
