AATCC 164 2015 Edition, January 1, 2015
Colorfastness to Oxides of Nitrogen in the Atmosphere under High Humidities
Additional Comments: SAME AS ISO 105-G04
Purpose and Scope
This test method is used to determine the resistance of the color of textiles to the action of oxides of nitrogen in the atmosphere at elevated temperatures with relative humidities above 85%.
On certain fibers, dyes do not readily fade at humidities below 85%. Testing at higher humidities is required to produce color changes that predict service fading under warm, humid conditions
