This International Standard specifies methods for obtaining a reduced sample of surfactants or detergents suitable for use as products, alone or in mixture, in powder, paste or liquid form. Reduction of the sample may be necessary for the following reasons: a) the preparation of a final sample or a laboratory sample, of mass greater than 250 g, from a homogenized bulk sample, of mass more than 500 g; (b) the preparation of several equivalent laboratory samples and/or contradictory samples and/or reserve samples, each with a mass greater than 250 g, from a final sample; c) preparation of a test sample from a laboratory sample.
