Introduction of GB/T 7771-2008

本标准代替GB/T 7771-1987《特殊同色异谱指数的测定　改变照明体》。
本标准规定了预测评价拼混染料色样与标准色样当改变照明体时的颜色相符效果的方法。
本标准适用于预测评价拼混染料色样与标准色样当改变照明体时的颜色相符效果。
本标准不适用于改变照明体时，单一色样产生的色差或三刺激值的变化问题。
本标准也不适用于由于改变色度观察者使等色性受到影响的问题。
本标准与GB/T 7771-1987相比主要变化如下：
———增加了“术语和定义”一章（本版的第3章）；
———删除了原标准4.2中的表1F照明体相对光谱功率分布数据和表2F照明体和CIE1964补充标准色度观察者色匹配函数的加权系数（1987年版的4.2）；
———增加了试验报告内容（本版的第8章）。
