《GB/T 6688-2008染料相对强度和色差的测定仪器法》由TC134（全国染料标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
本标准代替GB/T 6688-1986《染料相对强度的测定　仪器法》、GB/T 6689-1986《染料色差的测定　仪器法》。
本标准规定了非荧光染料染于纺织品时与标样的相对强度和色差的仪器法测定方法。
本标准适用于使用测色仪器对非荧光染料染于纺织品时与标样的相对强度和色差以及分色差进行的测定。
本标准与GB/T 6688-1986、GB/T 6689-1986相比主要变化如下：
―――本标准整合了GB/T 6688-1986和GB/T 6689-1986（GB/T 6689-1986 和GB/T 6688-1986的标题、本标准的标题）；
―――使用CMC（l∶c）色差公式取代CIELAB色差公式（GB/T 6689-1986 中的第4章，本版的6.4.2）；
―――增加了试验报告内容（本版的第7章）。
