标准摘要
[中文适用范围]: 本文件规定了使用 20°(方法 A)、45°(方法 B)、60°(方法 C)和 85°(方法 D)几何形状的阳极氧化铝平面样品的镜面反射率和镜面光泽度的测量方法,以及通过采用窄接收角的附加 45° 方法(方法 E)测量镜面反射率。 所描述的方法主要用于透明阳极氧化表面。 它们可以与彩色阳极氧化铝一起使用,但只能与颜色相似的铝一起使用。 [外文原描述]: This document specifies methods for the measurement of specular reflectance and specular gloss of flat samples of anodized aluminium using geometries of 20° (Method A), 45° (Method B), 60° (Method C) and 85° (Method D) and of specular reflectance by an additional 45° method (Method E) employing a narrow acceptance angle. The methods described are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but only with similar colours.
