NATIONAL FOREWORD

This Indian Standard (Part 2/Sec 5) (Second Revision) which is identical with ISO 3167 : 2014 ‘Plastics — Multipurpose test specimens’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Methods of Sampling and Test for Plastics Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.

This standard was originally published in 1997 and subsequently revised in 2013. The second revision of this standard has been undertaken to align it with the latest version of ISO 3167 : 2014. The major changes in this revision are as follows:

a) Normative References have been updated.

b) In Fig. 1 recommended values of overall length, radius and distance between broad parallel-sided portions of test specimens have been incorporated.

c) Sub-clause 4.1 ‘General’ has been updated.

d) New sub-clauses, 4.2 ‘Injection moulding of multipurpose test specimens’ and 4.3 ‘Compression moulding of multipurpose test specimens’ have been added.

e) A new annex, Annex B ‘Consequences of changes in geometry’ has been added.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
