IS/ISO 105 : Part A02 : 1993 Textiles - Tests for Colour Fastness - Part A02 : Grey Scale for Assessing Change in Colour

NATIONAL FOREWORD

This Indian Standard (Part A02) which is identical with ISO 105-AO2 :1993 ‘Textiles — Tests for colour fastness — Part A02: Grey scale for assessing change in colour’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Chemical Methods of Test Sectional Committee and approval of the Textile Division Council.

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. With the publication of this standard, 1S768:1982 ‘Methods for evaluating change in colour (tirstrevision)’ stands withdrawn,

The composition of Technical Committee responsible for the preparation of this standard is given in National Annex A.

In reporting the results of a test or analysis made in accordance with this standard, if the final value observed or calculated, is to be rounded off, it shall be done in accordance with IS 2:1960 ‘Rules for rounding off numerical values (revised)’.
