AATCC TM109-2016, Colorfastness to Ozone in the Atmosphere under Low Humidities
Developed in 1963 by AATCC Committee RA33 (revised 2011, reaffirmed and editorially revised 2016)
1. Purpose and Scope
1.1 This test method is intended for determining the resistance of the color of textiles to the action of ozone in the atmosphere at room temperatures with relative humidities not exceeding 67%.
2.1 A test specimen and a control specimen are simultaneously exposed to ozone in an atmosphere under ambient temperatures (64-82F) and relative humidities not exceeding 67%, until the control specimen shows a color change corresponding to that of a standard of fading. This exposure period constitutes one cycle. The cycle is repeated (1) until the specimen shows a definite color change or (2) for a prescribed number of cycles.
