This Indian Standard (Part G04) (First Revision) which is identical with ISO 105-G04 : 2016 ‘Textiles - Tests for colour fastness - Part G04 : Colour fastness to nitrogen oxides in the atmosphere at high humidities’ 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 Textiles Division Council.

This standard was originally published in 2017 which was identical with ISO 105-G04 : 1989 ‘Textiles - Tests for colour fastness - Part G04: Colour fastness to oxides of nitrogen in the atmosphere at high humidities.’ The first revision of this standard has been undertaken to align it with the latest version of ISO 105-G04 : 2016.
