标准范围

描述了两种暴露方法。在方法A中，材料在玻璃下暴露于自然光下。在方法B中，材料暴露于直接的人造光下。将试样和约定的参考颜料分别分散在相同的约定粘合剂中。将所述分散液施加到基质上并干燥；然后，在特定条件下，将其暴露在自然日光下，并进行防雨（方法A）或人工光（方法B）。通过比较试样颜色的变化与商定的参考颜料的颜色变化来评估耐光性。取消并替换第一版ISO 787/15-1973。

Describes two methods of exposure. In method A, the material is exposed under glass to natural light. In method B, the material is exposed to direct artificial light. The test sample and the agreed reference pigment are each dispersed in the same agreed binder. The dispersions are applied to a substrate and dried; they are then exposed to natural daylight with protection from rain (method A) or to artificial light (method B) under specified conditions. The resistance to light is assessed by comparing the change in colour of the test sample to that of the agreed reference pigment. Cancels and replaces the first edition ISO 787/15-1973.
