AATCC TM164 Colorfastness to Oxides of Nitrogen in the Atmosphere under High Humidities
Developed in 1985 by AATCC Committee RA33; editorially revised and reaffirmed 1986, 1997; reaffirmed 1987, 1992, 2011, 2006, 2013, 2020; editorially revised 1989, 1995, 2004, 2008, 2010, 2019; revised 2015. Technically equivalent to ISO 105-G04.
1. Purpose and Scope
1.1 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%.
1.2 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.
