标准摘要
[中文适用范围]： 本文件描述了评估聚烯烃管道、管件和化合物中碳黑或颜料颗粒及聚集物尺寸以及分散度的方法。该方法适用于聚烯烃管道和管件，以及以颗粒形式的原材料。所采用程序的选择由参考规范决定。该方法适用于碳含量小于3%（按重量计）的碳黑或颜料含量小于5%（按重量计）的着色聚烯烃管道、管件和化合物。 [外文原描述]： This document describes a method with two procedures for the assessment of carbon black or pigment particle and agglomerate size, and the rating of dispersion in polyolefin pipes, fittings and compounds. The method is applicable to polyolefin pipes and fittings, as well as raw material in pellet form, with the choice of procedure to be determined by the referring specification. The method is applicable to carbon black or pigmented polyolefin pipes, fittings and compounds with a carbon black content of less than 3 % by weight, and pigment content of less than 5 % by weight.
英文名称Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, fittings and compounds
