Scope of standard

1.1 This practice covers laboratory procedures for the preparation of granular and lump coke into briquette and block samples for examination with a reflected light microscope. The samples prepared are used for examination and identification of the components in coke and the measurement of the reflectance of coke. Note 1: Sieve size is identified by its standard designation in Specification E11. The alternative designation given in parentheses is for information only and does not represent a different standard sieve size 1.2 Units-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.
