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.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11,

Products.

This second edition cancels and replaces the first edition (ISO 12017:1995), of which it constitutes a

minor revision.
The changes compared to the previous edition are as follows:
— the normative reference clause (Clause 2) has been updated.

Any feedback or questions on this document should be directed to the user’s national standards body. A

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.
