Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2/Sec 3) (First Revision) which is identical with ISO 294-1 : 2017 ‘Plastics - Injection moulding of test specimens of thermoplastic materials — Part 1: General principles, and moulding of multipurpose and bar test specimens’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Method 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 2000 which was identical with ISO 294-1 : 1996. The first revision of this standard has been undertaken to align it with the latest version of ISO 294-1 : 2017.

The major changes in this revision are as follows:

a) the types of test specimen have been replaced according to ISO 20753;

b) Annex D has been added to clarify the methods for setting the operation parameters on injection machine;

c) the original Annex D has been renamed as Annex E; and

d) incorporates the Amendments ISO 294-1 : 1996/Amd.1 : 2001 and ISO 294-1 : 1996/Amd.2 : 2005.

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.
