Surface active agents - Determination of wetting power by immersion (ISO 8022:1990 modified) EN 1772:2000

Publication date:   Nov 3, 2001

Scope

This European Standard specifies a method for determining the wetting power of a surface active agent in solution by immersion of a disc of raw cotton cloth in the solution. The method is applicable to all surface active agents, whatever their ionic character, used as wetting agents in neutral, slightly acid or slightly basic baths for textile applications. The method is not applicable to mercerizing agents (baths highly basic) or to carbonizing assistants (baths highly acid).
