ISO 3167:1993(E) 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. Esch 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. 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. International Standard ISO 3167 was prepared by Technical Committee ISOFC 61, Plastics, Sub-Committee SC 2, Mechanical properties. This third edition cancels and replaces the second edition (ISO 3167:7983), which has been extended to introduce the preferred specimen type A with a smaller radius, in Order to facilitate the testing of Parts with simple machining for a variety of tests. WNh respect to existing moulds, the specimen type described in the sec- ond edition is included as type B. lt may be possible to eliminate type B at the next revision of this International Standard. The designations of dimensions are harmonized with those of the Inter- national Standards for testing which relate to a multipurpose test speci- men, in accordance with ISO 31. Annexes A and B of this International Standard are for information only. 0 ISO 1993 All rights reserved.

INTERNATIONAL STANDARD ISO 3167:1993(E) Plastics - Multipurpose test specimens 1 Scope 1.1 This International Standard specifies require- ments relating to muitipurpose test specimens for plastic moulding materials intended for processing by injection or direct compression moulding. 1.2 Spetimens of types A and B are tensile test specimens, from which with simple machining, specimens for a variety of other tests tan be taken (see annex A). Because they have such wide Utility, these tensile specimens are referred to in this Inter- national Standard as multipurpose test specimens. 1.3 The principal advantage of a multipurpose test specimen is that it allows all the test methods men- tioned 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 tan be expected that test results for a given set of speci- mens 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 tan be assessed without difficulty for all of the properties measured. 1.4 For quality-control purposes, the multipurpose test specimen may serve as a convenient Source of further specimens not readily available. Furthermore, the fact that only one mould is required may be ad- vantageous. 1.5 The use of multipurpose test specimens shall be agreed upon by the interested Parties, because there may be significant differentes between proper- ties of the multipurpose test specimens and those specified in the relevant test methods. 2 Normative references The following Standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
