1.1 This practice covers procedures for the collection of calcined petroleum coke samples from conveyor belts or transfer points. These samples may be used for physical and chemical analyses.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

4.1 Data obtained from calcined petroleum coke samples are used in commercial transactions, controlling plant operations, and allocating production costs. Use of standard sampling procedures facilitates the task of obtaining a sample to represent an entire lot of calcined petroleum coke.

4.2 This practice gives general procedures for the collection of calcined petroleum coke samples and is intended to provide useful methodology for the collection of a sample to represent a lot of calcined petroleum coke. The variety of calcined petroleum coke handling facilities and sampling applications preclude the publication of detailed procedures for every sampling situation.
