标准范围

ISO 4630-2:2004规定了一种使用颜色测量仪器，通过加德纳颜色标度估算透明、黄色/棕色液体产品颜色的方法。如果对其他产品进行测试，结果可能无效。该测试使用ISO 4630-1中描述的加德纳色标，该色标描述了一种视觉方法。本方法适用于干燥油脂、清漆、脂肪酸溶液、聚合脂肪酸、树脂、妥尔油、妥尔油脂肪酸、松香及相关产品。所述方法提供了比ISO 4630中所述更精确的加德纳颜色测量方法-1.适用于颜色从Gardner 1到Gardner 18的产品。加德纳标尺不适用于颜色小于1或小于18的产品。

ISO 4630-2:2004 specifies a method for estimating, by means of the Gardner colour scale, the colour of clear, yellow/brown liquid products using colour-measuring instruments. The results may be invalid if other products are tested. The test uses the Gardner colour scale described in ISO 4630-1, which describes a visual method.The method is applicable to drying oils, varnishes and solutions of fatty acids, polymerized fatty acids, resins, tall oil, tall oil fatty acids, rosin and related products.The method described provides a more precise way of measuring Gardner colour than that described in ISO 4630-1. It is applicable to products having colours from Gardner 1 to Gardner 18. The Gardner scale is not applicable to products with colours lighter than 1 or darker than 18.
