6 Test methods
6.1 General
6.1.1 Test conditions

Make all measurements under the standard conditions of 23 °C ± 2 °C and (50 ± 5) % relative humidity

(refer to ISO 291). For measurements made under local ambient conditions, due allowance shall be made

for dimensional changes due to the differences in temperature and relative humidity.

6.1.2 Sampling

The sampling procedure shall be agreed upon between the interested parties. The procedures described

in ISO 28590 and ISO 2859-1 are widely accepted and frequently used. Hence these are recommended

for sampling.
The test report shall include the following information:
a) a reference to this document, i.e. ISO 12017:2021;
b) all details necessary to identify the sample used for the tests.
6.1.3 Preparation of test specimens

Specimens shall be prepared in accordance with the procedures described in ISO 2818, wherever

applicable.
6.2 Thickness measurements
6.2.1 Total thickness

Measure the total thickness, to the nearest 0,1 mm, at 200 mm intervals over the whole extrusion width,

beginning at the central point of the edge cell. Calculate the average of the measurements.

6.2.2 Minimum skin thickness

Measure the thickness of the outer skins, to the nearest 0,1 mm, at the point of minimum thickness.

Do not report the thickness of the inner skin of a TSS; however, check to ensure that the inner skin is

intact.
6.2.3 Minimum rib thickness

Measure the rib thickness, to the nearest 0,1 mm, at the thinnest point of the thinnest rib.

6.2.4 Test report
The test report shall include the following measurements, accurate to 0,1 mm:
a) the average total thickness, minimum thickness and maximum thickness;
b) the minimum outer-skin thickness;
c) the minimum rib thickness.

SIST EN ISO 12017:2021
ISO 12017:2021(E)
6.3 Width and length measurements

Measure the extrusion width, the cut width (if necessary) and the sheet length in the extrusion direction

to the nearest 0,1 mm.
Report the width and the length measured.
6.4 Rib geometry

Report the nominal values of the rib spacing, the rib angles and any other relevant rib-geometry

parameters.
6.5 Mass per unit area

Weigh, to the nearest 1 g, strips with a width corresponding to the extrusion width and 100 mm in

length.

Calculate the mass per unit area, ρ , in kilograms per square metre, using Formula (1):

ρ = ×10 (1)
W×100
where
m is the mass, in grams, of the specimen;
W is the width, in millimetres, of the specimen.
Report the value of ρ calculated from Formula (1) to the nearest 0,01 kg/m .
6.6 Curvature of sheet surface

Measure the curvature on a full-size sheet, using a 1 000-mm-long straight edge (see Figure 6).

Figure 6 — Curvature of sheet surface

Place the specimen, in the vertical position (extrusion direction horizontal), on a plane horizontal

surface, and hold it upright. Place the straight edge against the concave surface of the sheet and measure

the maximum distance a between the sheet surface and the straight edge (1 000 mm secant line of

the curvature) in the extrusion direction. Similarly, measure the maximum curvature b at the cut ends

(perpendicular to the extrusion direction). If the width is less than 1 000 mm, measure the curvature b

over the full width.
Report the distances measured.
NOTE The sheet is normally longer than 1 000 mm.
6.7 Curvature of edge in extrusion direction

Measure the edge curvature on a full-size sheet at the side edges, using a 1 000-mm-long straight edge

(see Figure 7).

Place the test sheet in the horizontal position on a plane horizontal surface so that the sheet lies concave

side down. Measure the maximum distance с between a side edge of the sheet and the straight edge.

Report the distance measured.
6.8 Optical properties
6.8.1 Luminous transmittance
Measure the luminous transmittance by the method described in Annex A.

NOTE 1 Luminous transmittance of DSS and TSS cannot be measured accurately by the method given in

ISO 13468-1. Due to the complex geometry of DSS and TSS, it does not necessarily give reliable values.

NOTE 2 A spectrometer does not give reproducible results either.
6.8.2 Colour

The method used for the determination of colour and colour variations shall be agreed on between the

interested parties.
6.8.3 Appearance

Any defects shall be evaluated by inspecting the sheet under daylight or a daylight-type fluorescent

lamp with a colour temperature of 6 500 K ± 650 K and rated at not less than 40 W.

b) cracks;
c) crazing.
6.8.4 Test report
The test report shall include the following information, when measured:
a) the luminous transmittance;
b) the colour and colour variation;
c) details of any defects in appearance.
6.9 Thermal resistance

Measure the thermal resistance in accordance with ISO 8302 and include the results in a test report.

6.10 Three-point bending test
6.10.1 General

The bending test is an important criterion in assessing sheet quality and judging the consistency of the

extrusion process.
6.10.2 Procedure
Use specimens 100 mm long in the extrusion direction.

If the extrusion width is between 600 mm and 800 mm, use the whole width for the specimens. If the

extrusion width is greater than 800 mm, cut the specimen to 800 mm, taking it from any part of the

total width.

Carry out the test using a dynamometer (preferably instrumented) in the following way (see Figure 8):

Place the specimen symmetrically on two supports (edge radius 5 mm) spaced at 550 mm.

Apply the load at the centre of the specimen, evenly over its entire length (100 mm), using a loading edge

(radius 5 mm) pressing against a rubber mat (250 mm × 100 mm × 20 mm, nominal Shore A hardness

70) placed on the specimen.

NOTE The rubber mat is necessary in order to distribute the load over a larger surface area and hence

avoid the skin in contact with the loadin

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 non­governmental, 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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

6 Test methods
6.1 General
6.1.1 Test conditions

Make all measurements under the standard conditions of 23 °C ± 2 °C and (50 ± 5) % relative humidity

(refer to ISO 291). For measurements made under local ambient conditions, due allowance shall be made

for dimensional changes due to the differences in temperature and relative humidity.

6.1.2 Sampling

The sampling procedure shall be agreed upon between the interested parties. The procedures described

in ISO 28590 and ISO 2859-1 are widely accepted and frequently used. Hence these are recommended

for sampling.
The test report shall include the following information:
a) a reference to this document, i.e. ISO 12017:2021;
b) all details necessary to identify the sample used for the tests.
6.1.3 Preparation of test specimens

Specimens shall be prepared in accordance with the procedures described in ISO 2818, wherever

applicable.
6.2 Thickness measurements
6.2.1 Total thickness

Measure the total thickness, to the nearest 0,1 mm, at 200 mm intervals over the whole extrusion width,

beginning at the central point of the edge cell. Calculate the average of the measurements.

6.2.2 Minimum skin thickness

Measure the thickness of the outer skins, to the nearest 0,1 mm, at the point of minimum thickness.

Do not report the thickness of the inner skin of a TSS; however, check to ensure that the inner skin is intact.

6.2.3 Minimum rib thickness

Measure the rib thickness, to the nearest 0,1 mm, at the thinnest point of the thinnest rib.

6.2.4 Test report
The test report shall include the following measurements, accurate to 0,1 mm:
a) the average total thickness, minimum thickness and maximum thickness;
b) the minimum outer­skin thickness;
c) the minimum rib thickness.
6.3 Width and length measurements

Measure the extrusion width, the cut width (if necessary) and the sheet length in the extrusion direction

to the nearest 0,1 mm.
