Significance and Use
The procedure outlined in these practices are guides for obtaining descriptive samples of solid, semisolid and liquid waste from flowing streams, and incorporate many of the same procedures and equipment covered in the Referenced Documents. These practices by themselves will not necessarily result in the collection of samples representative of the total waste mass. The degree to which samples describe a waste mass must be estimated by application of appropriate statistical methods and measures of quality assurance. It is recommended that those practices be used in conjunction with Guide D 4687
1.1 Those practices provide guidance for obtaining samples of waste at discharge points from pipes, sluiceways, conduits, and conveyor belts. The following are included:
|Practice A—Liquid or Slurry Discharges|
Practice B—Solid or Semisolid Discharges
|7 through 9|
10 through 12
1.2 These practices are intended for situations in which there are no other applicable ASTM sampling methods (see Practices D 140 and D 75
1.3 These practices do not address flow and time-proportional samplers and other automatic sampling devices.
1.4 Samples are taken from a flowing waste stream or moving waste mass and, therefore, are descriptive only within a certain period. The length of the period for which a sample is descriptive will depend on the sampling frequency and compositing scheme.
1.5 It is recommended that these practices be used in conjunction with Guide D 4687
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Section 5 for more information.
