MT 174 - Dispersibility of water dispersible granules

 

Content Handbook F

 

Ouline of method

A known amount of a water dispersible granule (WG) is added to a defined volume of water and mixed by stirring to form a suspension. After standing for a short period, the top nine-tenths are drawn off and the remaining tenth dried and determined gravimetrically. The method is virtually a shortened test of suspensibility and is appropriate for establishing the ease with which a WG dispersed uniformly in water.
