标准摘要
[中文适用范围]： 本国际标准规定了使用颜色测量仪器通过加德纳色标估算光学透明、黄色/棕色液体产品颜色的方法。 该方法采用附录A中描述的加德纳色标。 它适用于干性油、清漆以及脂肪酸、聚合脂肪酸、树脂、妥尔油、妥尔油脂肪酸、松香及相关产品的溶液。 如果测试其他产品，结果可能无效。 所描述的方法提供了一种比使用人眼进行视觉样本比较更精确的加德纳颜色测量方法。 它适用于颜色从 Gardner 1 到 Gardner 18 的产品。 Gardner 等级不适用于颜色深于 18 的产品。 对于颜色浅于 Gardner 1 的产品，适用 ISO 6271 中指定的方法。 [外文原描述]： ISO 4630:2015 specifies a method for estimating the colour of optically clear, yellow/brownish coloured liquid products by means of the Gardner colour scale using colour-measuring instruments. The method uses the Gardner colour scale described in Annex A. It 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 results might be invalid if other products are tested. The method described provides a more precise way of measuring Gardner colour than a visual sample comparison using human eyes. It is applicable to products having colours from Gardner 1 to Gardner 18. The Gardner scale is not applicable to products with colours darker than 18. For products with colours lighter than Gardner 1 the method specified in ISO 6271 applies.
