标准摘要
[中文适用范围]： 本部分ISO 105提供了一种计算两个相同材料样品在相同条件下测量时色差的方法，使得总色差数值∆Ecmc(l:c)量化了两个样品不匹配的程度。它允许指定一个最大容差值，该值仅取决于给定最终用途所需的匹配程度，而与涉及的色相、色差性质无关。该方法还提供了一种建立亮度、色度和色相差异之间比率的手段。 [外文原描述]： ISO 105-J03:2009 provides a method of calculating the colour difference between two specimens of the same material, measured under the same conditions, such that the numerical value ∆ E cmc ( l : c ) for the total colour difference quantifies the extent to which the two specimens do not match. It permits the specification of a maximum value (tolerance) which depends only on the closeness of match required for a given end-use and not on the colour involved, nor on the nature of the colour difference. The method also provides a means for establishing the ratio of differences in lightness to chroma and to hue.
