Scope

This standard is applicable to the determination of the dispersion stability of vat dye (ultrafine powder) suspension. The determination method is to use the suspension of a certain concentration of the sample to be placed in a cylindrical glass separatory funnel, and after standing at room temperature for a certain period of time, measure the upper and bottom The absorbance of the reduced leuco body of the suspension is used to calculate the dispersion stability of the suspension of the sample, expressed as a percentage.
