NATIONAL FOREWORD

This Indian Standard (Part 3) which is identical with ISO 13936-3 : 2005 ‘Textiles - Determination of the slippage resistance of yarns at a seam in woven fabrics - Part 3: Needle clamp method’ 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.

Since ISO 13936 has been published in three parts, this standard has also been published in three parts. Other parts in this series are:

Part 1 Fixed seam opening method

Part 2 Fixed load method

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 atmospherictemperature 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 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.
