This test method is used to document the mass flowrate of resource recovery unit operations as a means of documenting the operating of a plant (or portions of a plant) and as a means of relating operation to design objectives.

This test method is also used in conjunction with measurements of the performance of materials separators (particularly recovery and purity). As such, throughput should not generally be measured by sampling the feed since this may change its performance. Processing equipment that does not perform separations can be sampled at either the feed or product streams.

1.1 This test method is for measuring the throughput, or mass flowrate, of a resource-recovery unit operation, or series of unit operations.

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.
