簡介

AATCC 109-2005標準是關於低濕度環境下耐臭氧色牢度的測試標準，AATCC 109標準由AATCC 組織R33小組與1963年提出，於1972、1986、1987進行過修訂，1971、1975、1983、1992、2002、2005進行重申，部分相當於 ISO 105-G03標準。

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. Principle

2.1 A test specimen and a control specimen are simultaneously exposed to ozone in an atmosphere under ambient temperatures (64-82°F) 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 c
