Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19712-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

8 Resistance to impact by large-diameter ball
8.1 Principle
A specimen taken from the sheet under test is covered with a sheet of carbon paper and subjected to the
impact of a steel ball, which is allowed to fall from a known height. Impact resistance is expressed as the
maximum drop height which can be achieved without incurring visible surface cracking or producing an imprint
greater than a specified maximum diameter.
8.2 Apparatus
8.2.1 Free-fall test apparatus, of the type shown in Figure 4, or an equivalent which will produce the same
results.
8.2.2 Polished steel ball, of mass (324 ± 5,0) g and diameter (42,8 ± 0,2) mm, having no damaged or
flattened areas on its surface.
8.2.3 Specimen clamping frame, conforming to Figure 5.
8.3 Test specimens
Specimens shall measure (230 ± 0,5) mm × (230 ± 0,5) mm × the thickness of the sheet under test.
8.4 Procedure
The test shall be carried out in the laboratory atmosphere, and in cases of dispute it shall be carried out at
(23 ± 2) °C.
Clamp a specimen in the clamping frame (8.2.3) and place the assembly on the solid base of the free-fall test
apparatus (8.2.1). Cover the specimen with a sheet of carbon paper with its coated face in contact with the
decorative surface. Adjust the height scale so that its base is touching the face of the specimen.
Position the electromagnet at any arbitrary height (the specification limit for the material under test is a useful
starting point).
Place the steel ball (8.2.2) on the energized electromagnet. Operate the release mechanism so that the ball
falls on the specimen, catching the ball on the first rebound so that multiple impacts do not occur.
Examine the impact spot. If cracking is evident, or the carbon imprint is greater than the diameter specified in
ISO 19712-1, lower the electromagnet and repeat the test. If no cracking is evident and the imprint is smaller
than the specified diameter, raise the electromagnet and repeat the test. The distance between points of
impact, and between points of impact and the edge of the specimen, shall be at least 50 mm. For referee
purposes, only one impact per specimen shall be made, with the point of impact as near as possible to the
centre of the specimen.
Repeat the above procedure, as necessary, to determine the impact resistance, which is defined as the
maximum height for which no visible surface cracking, or imprint greater than the specified diameter, occurs in
five successive strikes.

e) any deviation from the method specified;
f) the date of the test.
9 Lightfastness
9.1 Method A
9.1.1 Principle
A specimen taken from the sheet under test is exposed to daylight simulated by the filtered light of one or
more xenon-arc lamps. The effect on the colour of the specimen, at a specified radiant exposure, is assessed
by the contrast between the exposed and unexposed portions of the test specimen. The radiant exposure is
determined both instrumentally and by assessing the effect on blue wool references which are exposed
simultaneously.
Daylight spectral distribution is specified since SSM sheets may, in certain applications, be exposed to direct
daylight through open windows.
9.1.2 Apparatus
9.1.2.1 Test device, as specified in ISO 4892-1 and ISO 4892-2, equipped with:
a) one or more xenon-arc lamps, filtered to provide a spectral energy distribution which closely
approximates to that of solar irradiance as described in CIE Publication No. 85:1989, Table 4, and
ISO 4892-2:2006, Table 1 (method A);
b) stainless-steel specimen holders, in the form of an open frame, which provide the test specimens with a
solid backing;
c) a black-standard thermometer as specified in ISO 4892-1;
d) a photoelectronic sensor (radiometer) of one of the types specified in ISO 9370 to measure the irradiance
and the radiant exposure at the specimen surface in the wavelength range 300 nm to 400 nm, or at
340 nm.
9.1.2.2 Viewing enclosure, having a matt interior colour corresponding approximately to Munsell N5. It
shall be equipped with an artificial light source, located at the top, simulating average north sky daylight (e.g.
tungsten-halogen incandescent lamps) and generating a colour temperature of (6 500 ± 200) K and at least
800 lx at the surface of the specimen. The viewing enclosure shall be placed in a position where the
surrounding lighting conditions will not affect the visual assessment of the specimen.
9.1.3 Test specimen
One test specimen shall be prepared, of a size suitable for the specimen holder used and appropriate for the

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19712-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.

8 Resistance to impact by large-diameter ball
8.1 Principle
A specimen taken from the sheet under test is covered with a sheet of carbon paper and subjected to the
impact of a steel ball, which is allowed to fall from a known height. Impact resistance is expressed as the
maximum drop height which can be achieved without incurring visible surface cracking or producing an imprint
greater than a specified maximum diameter.
8.2 Apparatus
8.2.1 Free-fall test apparatus, of the type shown in Figure 4, or an equivalent which will produce the same
results.
8.2.2 Polished steel ball, of mass (324 ± 5,0) g and diameter (42,8 ± 0,2) mm, having no damaged or
flattened areas on its surface.
8.2.3 Specimen clamping frame, conforming to Figure 5.
8.3 Test specimens
Specimens shall measure (230 ± 0,5) mm × (230 ± 0,5) mm × the thickness of the sheet under test.
8.4 Procedure
The test shall be carried out in the laboratory atmosphere, and in cases of dispute it shall be carried out at
(23 ± 2) °C.
Clamp a specimen in the clamping frame (8.2.3) and place the assembly on the solid base of the free-fall test
apparatus (8.2.1). Cover the specimen with a sheet of carbon paper with its coated face in contact with the
decorative surface. Adjust the height scale so that its base is touching the face of the specimen.
Position the electromagnet at any arbitrary height (the specification limit for the material under test is a useful
starting point).
Place the steel ball (8.2.2) on the energized electromagnet. Operate the release mechanism so that the ball
falls on the specimen, catching the ball on the first rebound so that multiple impacts do not occur.
Examine the impact spot. If cracking is evident, or the carbon imprint is greater than the diameter specified in
ISO 19712-1, lower the electromagnet and repeat the test. If no cracking is evident and the imprint is smaller
than the specified diameter, raise the electromagnet and repeat the test. The distance between points of
impact, and between points of impact and the edge of the specimen, shall be at least 50 mm. For referee
purposes, only one impact per specimen shall be made, with the point of impact as near as possible to the
centre of the specimen.
Repeat the above procedure, as necessary, to determine the impact resistance, which is defined as the
maximum height for which no visible surface cracking, or imprint greater than the specified diameter, occurs in
five successive strikes.

e) any deviation from the method specified;
f) the date of the test.
9 Lightfastness
9.1 Method A
9.1.1 Principle
A specimen taken from the sheet under test is exposed to daylight simulated by the filtered light of one or
more xenon-arc lamps. The effect on the colour of the specimen, at a specified radiant exposure, is assessed
by the contrast between the exposed and unexposed portions of the test specimen. The radiant exposure is
determined both instrumentally and by assessing the effect on blue wool references which are exposed
simultaneously.
Daylight spectral distribution is specified since SSM sheets may, in certain applications, be exposed to direct
daylight through open windows.
9.1.2 Apparatus
9.1.2.1 Test device, as specified in ISO 4892-1 and ISO 4892-2, equipped with:
a) one or more xenon-arc lamps, filtered to provide a spectral energy distribution which closely
approximates to that of solar irradiance as described in CIE Publication No. 85:1989, Table 4, and
ISO 4892-2:2006, Table 1 (method A);
b) stainless-steel specimen holders, in the form of an open frame, which provide the test specimens with a
solid backing;
c) a black-standard thermometer as specified in ISO 4892-1;
d) a photoelectronic sensor (radiometer) of one of the types specified in ISO 9370 to measure the irradiance
and the radiant exposure at the specimen surface in the wavelength range 300 nm to 400 nm, or at
340 nm.
9.1.2.2 Viewing enclosure, having a matt interior colour corresponding approximately to Munsell N5. It
shall be equipped with an artificial light source, located at the top, simulating average north sky daylight (e.g.
tungsten-halogen incandescent lamps) and generating a colour temperature of (6 500 ± 200) K and at least
800 lx at the surface of the specimen. The viewing enclosure shall be placed in a position where the
surrounding lighting conditions will not affect the visual assessment of the specimen.
9.1.3 Test specimen
One test specimen shall be prepared, of a size suitable for the specimen holder used and appropriate for the
method of assessment after exposure.
