Standard Practice for Sampling Industrial Chemicals

Importancia y uso:

5.1 Representative samples of industrial chemicals are required for the determination of chemical and physical properties which are used to establish standard volumes, prices, and compliance with commercial and regulatory specifications.

5.2 The objective of sampling is to obtain a small portion (spot sample) of material from a selected area within a container which is representative of the material in the area or, in the case of running or all-level samples, a sample whose composition is representative of the total material in the container. A series of spot samples may be combined to create a representative sample.

5.3 Manual and Automatic Sampling Considerations—The selection of manual or automatic sampling devices is part of establishing a sampling plan applied under all conditions within the scope of this practice provided that the proper sampling procedures are followed. Both types of sampling are commonly used for liquid, solid, and slurry sampling and require adherence to the following:

5.3.1 An adequate frequency of sampling must be selected.

5.3.2 The equipment to support manual or automatic sampling systems may be obtained commercially, fabricated from the designs presented in this practice, or constructed as needed to satisfy process design or other specific requirements.

5.3.3 The sampling equipment must be maintained on a regular basis, and the sampling plan adopted must be strictly followed.
