NATIONAL FOREWORD

This Indian Standard (Part 3) (First Revision) which is identical with ISO 2796 :1986' Cellular plastics, rigid — Test for dimensional stability' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Thermal insulation Sectional Committee and approval of the Chemical Division Council.

This standard was originally published in 1985.This revision of the standard has been taken up to align it with ISO 2796 :1986 by adoption under dual numbering system.
