本试验通过在水介质中标准条件下分散染料的过滤时间和过滤残留物来确定分散性。规定了影响试验准确性和重复性的变量。本试验方法仅用于测定水介质中规定条件下的分散度。一定量的分散染料经过预稀释、加热并通过规定微米尺寸的滤纸。然后评估染料的通过时间和保留时间。根据预期染料应用概述了三项测试。

This test determines the dispersibility as evaluated by filtering time and filter residue of disperse dyes under standard conditions in aqueous media. Variables which affect accuracy and repeatability of the test are specified.This test method is to be used for determining the degree of dispersion at the specified conditions in aqueous media only.A quantity of disperse dye is prediluted, heated and passed through filter papers of specified micron size. The time of passage and retention of dye is then evaluated. Three tests are outlined according to intended dye application.
