ASTM D2616用灰度标评定视觉色差的标准试验方法—适用范围
Scope:
This test method describes a painted gray scale and the procedure to be used in the visual evaluation of color differences of non-self luminous materials by comparison to this scale.
对染色灰阶和对通过与染色灰阶的比较而对非自发光材料的色差执行视觉评定时所用的程序，本标准进行了描述
ASTM D2616用灰度标评定视觉色差的标准试验方法—试验意义与应用
The total perceived color difference between two non- self luminous specimens is compared as an equivalent lightness difference between two neutral gray specimens on a gray scale. A fundamental assumption is made that the total color difference can be so evaluated in terms of an equivalent lightness difference. Only the total color differences, that is, a summation of the differences in hue, lightness, and chroma between two specimens is evaluated; this test method is not applicable to the separate precise evaluation of the hue, lightness, and chroma components of color difference.
将两个非自发光样品之间的总感知色差作为两个中性灰色样品在灰阶上的等效明度差进行比较。一个基本的假设是，总色差可以用等效的明度差来计算。仅评估总色差，即两个试样之间色调、明度和色度差异的总和；本检查法不适用于单独精确评估色差的色调、明度和色度成分
