UNE 55-833-1986 Sampling methods for chemical products of detergent formulation raw materials and solid particulate (volume size between powder and sol) products
This standard describes the general techniques to separate the elementary intakes (Préle-vements - Increments) and to prepare the samples intended for the evaluation of a batch of solid chemical product, during the implementation of the sampling plan previously defined based on the objective sought. . This plan must comply with what is established by the appropriate standard. This standard is applicable to solid chemical products, which are presented in the form of granules, whose size varies between powder and coarse agglomerate, when supplied in large containers (for example, 25, 50,100 kg), or in bulk. This standard is not applicable to products resulting from the solidification of a molten mass, nor to plastic products. NOTE — This standard requires the use of appropriate terminology, such as that established in the UNE 55-549 standard.
