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 fifth edition results from the reinstatement of the previous edition (ISO 3167:2002) which was
withdrawn in 2013.
ISO 3167 is intended to be gradually replaced by ISO 20753 which specifies the designations and
dimensions of test specimens used for the acquisition of comparable data, and also other frequently
used specimens, in one document for ease of reference.

INTERNATIONAL STANDARD ISO 3167:2014(E)
Plastics — Multipurpose test specimens
1 Scope
This International Standard specifies requirements relating to multipurpose test specimens for plastic
moulding materials intended for processing by injection or direct compression moulding.
Specimens of types A and B are tensile test specimens from which, with simple machining, specimens
for a variety of other tests can be taken (see Annex A). Because they have such wide utility, these tensile
specimens are referred to in this International Standard as multipurpose test specimens.
The principal advantage of a multipurpose test specimen is that it allows all the test methods mentioned
in Annex A to be carried out on the basis of comparable mouldings. Consequently, the properties
measured are coherent as all are measured with specimens in the same state. In other words, it can be
expected that test results for a given set of specimens will not vary appreciably due to unintentionally
different moulding conditions. On the other hand, if desired, the influence of moulding conditions and/or
different states of the specimens can be assessed without difficulty for all of the properties measured.
For quality-control purposes, the multipurpose test specimen can serve as a convenient source of
further specimens not readily available. Furthermore, the fact that only one mould is required may be
advantageous.
The use of multipurpose test specimens is to be agreed upon by the interested parties, because there may
be significant differences between properties of the multipurpose test specimens and those specified in
the relevant test methods.

3 Dimensions of test specimens
For the purposes of this International Standard, the preferred multipurpose test specimen is the type A
tensile specimen shown in Figure 1. This can be made suitable for a variety of other tests by simple
cutting, because the length l of its narrow parallel-sided portion is 80 mm ± 2 mm.

a
The recommended overall length of 170 mm for type A is consistent with ISO 294-1 and ISO 10724-1. For some materials,
the length of the tabs may need to be extended (e.g. to give an overall length of 200 mm) to prevent breakage or slippage in
the jaws of the test machine.
b
The recommended values and ranges may become mandatory on occasion of the next revision of the standard. The
lower tolerances on the radius reduce the ranges of the stress concentrations that are found at the transitions between the
narrow parallel-sided and the rounded portions. Together with the smaller tolerance on the distance between the broad
parallel-sided portions for type B, a common value of the initial distance between jaws can be used for tensile testing (see
ISO 527-2).
