Significance and Use
4.1 This practice provides field personnel and laboratories with standard procedures for dividing, reducing, and mixing gross samples and intermediate samples, such that the resulting prepared analysis samples are more uniform from laboratory to laboratory. Adherence to these guidelines is expected to provide significant reduction in interlaboratory variability.
1.1 This practice covers the preparation procedures necessary for the reduction and division of calcined petroleum coke samples in order to generate appropriate analytical samples upon which physical and chemical analytical tests will be performed.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.
