Standard Practices for Sampling Wastes from Pipes and Other Point Discharges
|Publication Date:||1 September 2016|
These 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
These practices are intended for situations in which there are no other applicable ASTM sampling methods (see Practices D140 and D75) for the specific industry.
These practices do not address flow and timeproportional samplers and other automatic sampling devices.
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.
It is recommended that these practices be used in conjunction with Guide D4687.
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.
