ASTM D2244计算仪器测量颜色的颜色容差和色差的标准实践规程—适用范围
Scope:
This practice covers the calculation, from instrumentally measured color coordinates based on daylight illumination, of color tolerances and small color differences between opaque specimens such as painted panels, plastic plaques, or textile swatches. Where it is suspected that the specimens may be metameric, that is, possess different spectral curves though visually alike in color, Practice D4086 should be used to verify instrumental results. The tolerances and differences determined by these procedures are expressed in terms of approximately uniform visual color perception in CIE 1976 CIELAB opponent-color space (1), 2 CMC tolerance units (2), CIE94 tolerance units (3), the DIN99 color difference formula given in DIN 6176(4), or the new CIEDE2000 color difference units
