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.
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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
This second edition cancels and replaces the first edition (ISO 16012:2004), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 16012:2004/Cor.1:2005.

INTERNATIONAL STANDARD ISO 16012:2015(E)
Plastics — Determination of linear dimensions of test
specimens
1 Scope
This International Standard specifies measuring equipment and procedures for the determination
of the linear dimensions of rigid plastics test specimens. It is applicable to test specimens described
in ISO 20753 but can also be used for other test specimens, and to thicknesses typically in the range
0,4 mm ≤ h ≤ 6,4 mm.
NOTE Determination of dimensions of test specimen made of semi-rigid materials (70 MPa ≤ E ≤ 700 MPa)
[1]
can follow ISO 23529:2010 .
