本文件规定了测定各种颜色的色牢度和老化性能的方法 以及在人造纤维作用下染色和印刷的纺织品和/或其他有机基质的形式 代表自然日光的光源（D65），并在热的同时作用下。关于 规定了五组不同的暴露条件（见7.1.1），四组使用D65，另一组使用 有点低的截止波长。试验方法特别考虑了光和热 汽车内部发生的状况。 使用指定的不同光学滤波器系统的五组不同条件可以产生 不同的测试结果。使用不同仪器（仪器类型）进行试验的结果 同一组条件和光学滤波系统是不可比的，因为它们的性能是可比的 尚未验证。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for determining the colour fastness and ageing properties of all kinds and forms of dyed and printed textiles and/or other organic substrates under the action of an artificial light source representative of natural daylight (D65), and under the simultaneous action of heat. Of the five different sets of exposure conditions specified (see 7.1.1), four use D65, and the other one uses a somewhat lower cut-off wavelength. The test method gives special consideration to the light and heat conditions that occur in the interior of a motor vehicle. The five different sets of conditions using the different optical filter systems specified can produce different test results. Results from tests performed using different apparatus (instrument types) for the same set of conditions and optical filter system are not comparable because comparable performance has not been validated.All current amendments available at time of purchase are included with the purchase of this document.
