IS/ISO 105 : Part E16 : 2006 : Textiles - Tests for Colour Fasteness Part E 16 Colour Fastness to Water Sportting on Upholstery Fabrics

NATIONAL FOREWORD

This Indian Standard (Part E16) which is identical with ISO 105-E16 : 2006 ‘Textiles — Tests for colour fastness — Part E16: Colour fastness to water spotting on upholstery fabrics’ 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.

Since colour fastness is one of the most important requirement for export of textiles, it is considered essential that Indian Standards related to colour fastness are completely harmonized with International Standards. The various Indian Standards on colour fastness testing, are, therefore, being revised to align them with the corresponding International Standards. The Indian Standards are being published in Parts A to Z.

This standard finds application in measurement of colour fastness of textile materials to water spotting on upholstery fabrics.

The text of ISO Standard has been approved as suitable for publication as 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.
