47、DUCTIONThe previous version of the manual sampling practice described the various sampling methods andapparatus, with much focus on crude oils and semi-solids and solids. Also, previous versions did notsignificantly address closed or restricted sampling, which continue to become more prevalent.This
48、version will provide guidance on manual sampling terminology, concepts, equipment,containers, procedures, and will provide some specific guidance related to particular products andtests. The type and size of the sample obtained, and the handling method, will depend on the purposefor which it was tak
49、en. Refer to the test method for any specific sampling and handling requirementsup to the point of testing. It remains the responsibility of the subcommittee for the relevant test methodto provide guidance, or warnings, regarding sample container selection; preparation; cleanliness; heat,pressure, or light; sample size requirements for testing and retention; and any other special handlingrequirements necessary to ensure a representative sample is tested.In addition to the individual test method, for guidance on container, size, mixing and specialhandling, further guidance may be p
