Description

ASTM D3997/D3997M-24

Active Standard: Standard Practice for Preparing Coke Samples for Microscopical Analysis by Reflected Light

ASTM D3997/D3997M

Scope

1.1 This practice covers laboratory procedures for the preparation of granular and lump coke into block and briquet samples for examination with a reflected light microscope. The samples prepared are used for examination and identification of the components in coke microtexture, the measurement of the reflectance of coke, and the analysis of coke microstructure.

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, or other non-SI units, are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other and values from the two systems shall not be combined.

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.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
