IS 12673 : Part 4 : 2014/ISO 12947-4 : 1998 : Textiles -Determination of the Abrasion Resistance of Fabrics by the Martindale Method Part 4 Assessment of Appearance Change

Reaffirmed 2023

NATIONAL FOREWORD

This Indian Standard (Part 4) (First Revision) which is identical with ISO 12947-4 : 1998 ‘Textiles — Determination of the abrasion resistance of fabrics by the Martindale method — Part 4: Assessment of appearance change’ 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 1989 and now revise to align it with the latest version of ISO 12947-4 : 1998 which has been published in four parts. Similarly this standard has also been published in four parts. The other parts in this series are:

Part 1 Martindale abrasion testing apparatus

Part 2 Determination of specimen breakdown

Part 3 Determination of mass loss

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 especially 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.

Technical corrigendum 1 published in 2002 to the above International Standard has been given at the end of this publication.

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.
