BS EN 15647:2009 Surface active agents. Determination of the dispersing effect of surfactants on powder
BS EN 15647 specifies a method for the determination of the effectiveness of surface active agents to create and to stabilize a dispersion of pigment powder in water. It is applicable to all classes of surface active agents and formulations of surface active agents.
The method specified in BS EN 15647 can also be applied analogously to other powders.
