摘　　要：颜色定量评定的关键因素是对反射率的精确测量。随着纺织业电子色彩交流的不断发展，了解仪器之间颜色测量值的变异性是很重要的。为此，AATCC颜色测量测试方法委员会倡导了一项关于多个实验室对23对平纹染色织物的L^＊、a^＊、b^＊及色差值进行测定的研究，并对实验室间色度值的统计变率作了评价。结果发现L^＊、a^＊、b^＊的偏离值比△J^＊、△a^＊、△b^＊的大，这些统计数据将有助于改进AATCCTM173中的精度及误差要求。A critical factor in the quantitative assessment of color is the accurate and precise measurement of reflectance factors. The textile industry’s move toward electronic color communication means that knowledge of the inter-instrument variability among reflectance spectrophotometers is vital. A multi-laboratory assessment of 23 plain-weave, dyed fabric pairs was conducted. As part of a study conducted by the AATCC Color Measurement Test Methods Committee, L* ,a*, b*, and color difference data have been accumulated. This study assessed the statistical variability in colorimetric data obtained from the inter-laboratory trials. Variance in absolute L* ,a*, and b*,was found to be larger than the variance in color difference (△ L* , △ a* , and △ b* ). The data will be used to develop a precision and bias statement for AATCC Test Method 173.
