测试方法是“The colour shall be measured in accordance with the procedures defined in CIE publication No. 15.2, using an instrument with polychromatic illumination (CIE D65 illuminant). The instrument shall have a 45/0 illuminating and viewing geometry. The colour coordinates shall be determined using CIE standard illuminant D65 and 2° standard observer (=CIE 1931 standard colorimetric observer). The specimen shall be measured with a single layer including any backing or lining used in its constructions and backed by a black underlay with a reflectance of less than 0,04.” 在国内检验机构如SGS,TUV等，不能测试，要在国外测试，但国内一些小型机构可以测试，但测试结果差别很大。不知什么原因。
