Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 6/Sec 6) (Second Revision) which is identical with ISO 4589-1 : 2017 ‘Plastics — Determination of burning behaviour by oxygen index — Part 1: General requirements’ 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 1994, which was based on ISO 4589 : 1984. ISO 4589 : 1984 has subsequently been revised as ISO 4589-1 : 1996 ‘Plastics — Determination of burning behaviour by oxygen index — Part 1: Guidance’, ISO 4589-2 : 1996 ‘Plastics — Determination of burning behaviour by oxygen index — Part 2: Ambient-temperature test’ and ISO 4589-3 : 1996 ‘Plastics — Determination of burning behaviour by oxygen index — Part 3: Elevated temperature test’.

First revision of this standard was identical with ISO 4589-1 : 1996. ISO 4589-2 : 1996 and ISO 4589-3 : 1996 are separately covered under IS 13360 (Part 6/Sec 19) : 2000 and IS 13360 (Part 6/Sec 20) : 2000 under dual numbering. The second revision of this standard has been undertaken to align it with the latest version of ISO 4589-1 : 2017.

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.
