IS/ISO 105 : Part E07 : 2010 : Textiles - Tests for Colour Fastness Part E07 Colour Fastness to Spoting : Water

Reaffirmed 2021

NATIONAL FOREWORD

This Indian Standard (Part E07) which is identical with ISO 105-E07 : 2010 ‘Textiles - Tests for colour fastness - Part E07 : Colour fastness to spotting : water’ 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.

Colour fastness of dyed/printed textile materials to various agencies during their further treatment or actual use is an important performance requirement from the viewpoint of the user or consumer. The various agencies to which textile materials may be subsequently subjected may include water, acids, alkalis, organic solvents, washing, laundering, drycleaning, perspiration, light, gaseous fumes, bleaching, rubbing, carbonizing, felting, etc and the colour of textile materials should be fast to these agencies and should not change considerably. The colour should also not bleed and stain the adjacent fabrics which are subjected to these agencies along with coloured fabrics. The colour fastness property of coloured textiles is, therefore, measured in terms of colour fastness ratings with respect to change in colour and/or staining of adjacent fabrics.
