IS 7702 : 2012 : Textiles-Determination of Thickness of Textiles and Textile Products

Reaffirmed 2021

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 5084 : 1996 ‘Textiles - Determination of thickness of textiles and textile products’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Physical Methods of Test Sectional Committee and approval of the Textile Division Council.

This standard was first published in 1975 and has been revised to align it with the latest ISO 5084 : 1996 by adoption under dual numbering system.

The conditioning temperature of 20 ± 2°C as specified in International Standards is not suitable for tropical countries like India where the atmospheric temperature is normally much higher than 20°C. It is almost impossible to maintain this temperature specially during summer when the atmospheric temperature rises even up to 50°C. In view of the above, IS 6359 : 1971 ‘Method for conditioning of textiles’ which specifies a temperature of 27 ± 2°C for conditioning of the test specimens for the tropical countries like India shall be referred.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard with the above 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.
