Standard Practice for Sampling Liquids Using Grab and Discrete Depth Samplers

Importancia y uso:

4.1 Sampling at specified depth(s) within a liquid may be needed to confirm or rule out variations within a target population. This practice describes the design and operation of commercially available grab and discrete depth samplers for persons responsible for designing or implementing sampling programs, or both.

4.2 These sampling devices are used for sampling liquids in tanks, ponds, impoundments, and other open bodies of water. Some may be used from the edge or bank of the sampling site, whereas some can only be used from a platform, boat, or bridge over the sampling site. Some of the devices described are suitable for sampling slurries and sludges as well as aqueous and other liquids with few or no suspended solids.

4.3 Practice D5743 provides guidance for sampling drums, tanks, or similar containers.

4.4 This practice does not address general guidelines for planning waste sampling activities (Guide D4687), development of data quality objectives (Practice D5792), the design of monitoring systems and determination of the number of samples to collect (Practice D6311), in situ measurement of parameters of interest, data assessment, and statistical interpretation of resultant data (Guide D6233), sample preservation, sampling and field quality assurance (Guide D5612), or the selection of sampling locations or obtaining a representative sample (Guide D6044).
