Content Handbook Q

Outline of method

A sample of the formulation is dispersed in water and the suspension formed is transferred to a sieve and washed. The amount of the material retained on the sieve is determined by drying and weighing.

Scope

The method is suitable for the determination of the amount of non-dispersible material in formulations, that are applied as dispersions in water.

Reason for the revision

The objective of revision was to combine MT 185 and MT 182 into a single method. The procedure was simplified, editorial changes have been made and obsolete references have been removed.

Important note

Where the same conditions are used, results obtained with MT 185.1 are equivalent to those obtained with MT 185 or MT 182. MT 185.1 supersedes MT 185 and MT 182.
