BS EN ISO 23900-3:2018规定了测定聚乙烯（PE）着色性能的方法 一种测试颜料相对于一种标准的分散性，以及DHPE颜料分散性的差异 在不同条件下分散着色剂的颜色强度。方法A适用于有机粉末颜料和粉末中的炭黑颜料 无机颜料的形态，其中许多要经过压实（在压力下重新凝聚） 粉状和粉状或片状颜料制剂。方法B适用于测试颗粒状颜料和颜料制剂，以及 任何形式的无机颜料。以这种方式确定的分散易度仅对分散设备有效，即分散 使用的条件和分散介质。使用不同于规定的试验条件 可能会产生不同的结果；这既适用于绝对震级，也适用于两者之间的关系 各种颜料的易分散性值。因此，下标DHPE用于指定 根据ISO 23900本部分规定获得的值。交叉引用:ISO 787-24:1985ISO 18314-1ISO 15528EN 12877-1购买本文件时可获得的所有现行修订版均包含在购买本文件中。

BS EN ISO 23900-3:2018 specifies a method of determining in polyethylene (PE) the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DHPE of pigments from the differences in colour strength on dispersing colouring materials under various conditions.Method A is appropriate for use with organic powder pigments and carbon black pigments in powder form, many of which are subject to compaction (reagglomeration under pressure), for inorganic pigments in powder form and for pigment preparations in powder or flake form.Method B is appropriate for testing pigments and pigment preparations in granular form and for inorganic pigments in any form.The ease of dispersion determined in this way is valid only for the dispersion equipment, dispersion conditions and dispersion medium being used. The use of test conditions differing from those specified may give different results; this applies both to the absolute magnitude and to the relation between values of the ease of dispersion of various pigments. The subscript DHPE is therefore used to designate the value obtained as specified in this part of ISO 23900.Cross References:ISO 787-24:1985ISO 18314-1ISO 15528EN 12877-1All current amendments available at time of purchase are included with the purchase of this document.
