标准摘要
[中文适用范围]： 仅适用于透明、浅色液体。 这种颜色特征被描述为棕黄色。 该原理基于样品颜色与颜色标准颜色的视觉比较。 结果以铂-钴标度表示。 对于常规控制目的，如果如此获得的值与通过目视比较获得的值相同，则可以使用比较器、色度计或分光光度计。 [外文原描述]： Applicable only to clear, slightly coloured liqids. Such colour characteristics are described as brownish-yellow. The principle is based on a visual comparison of the colour of a sample with that of colour standards. The results are expressed in terms of the platinum-cobalt scale. For routine control purposes a comparator, colorimeter or spectrophotometer may be used, if the values so obtained are identical with those obtained by visual comparison.
