New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 18830 : 2016 ‘Plastics - Determination of aerobic biodegradation of non-floating plastic materials in a seawater/sediment interface - Method by measuring the oxygen demand in closed respirometer’ 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.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain 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
