New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 2/Sec 5) (Second Revision) which is identical with ISO 48-5 : 2018 ‘Rubber, vulcanized or thermoplastic - Determination of hardness - Part 5: Indentation hardness by IRHD pocket meter method’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation(s) of the Methods of Test for Rubber and Rubber Products Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.

The standard, was published in 2002 as IS 3400 (Part 23) under dual numbering with ISO 7619 : 1997. Since ISO 7619 has been revised in 2010 and split in to two parts, the Sectional Committee decided to align IS 3400 (Part 23)with the latest International Standards available on the subject. As this Indian Standard is already part of seriesof standards, it was further decided to publish the two different parts of ISO 7016 as two sections of standard namely IS 3400 (Part 23/Sec 1) and IS 3400 (Part 23/Sec 2).
