本技术报告介绍了工业色差评估的推荐实施规程。推荐的模型是CIE 1976（L*a*b*）色差模型的扩展，根据亮度、色度、色调和色度-色调相互作用对色差感知的变化进行校正。根据新的实验数据和分析，对CIE94模型中色度和色调差异的色度依赖性进行了修正，并进行了补充。参考条件定义了色差模型适用的材料和观察环境特征。引入了校正各种使用条件的参数效应的因素。技术报告以英文编写，并附有法文和德文的简短摘要。它由15页和2个表格组成。

In this Technical Report recommended practice for industrial colour-difference evaluation is presented. The recommended model is an extension of the CIE 1976 (L*a*b*) colour-difference model with corrections for variation in colour-difference perception dependent on lightness, chroma, hue and chroma-hue interaction. The corrections for the chroma dependence of chroma and hue differences in the CIE94 model have been retained and supplemented by several additional corrections based on new experimental data and analysis. Reference conditions define material and viewing environment characteristics to which the colour-difference model applies. Factors are introduced to correct for the parametric effects of various conditions of use.The Technical Report is written in English, with a short summary in French and German. It consists of 15 pages with 2 tables.
