Significance and Use
Briquettes of granular coke prepared in accordance with the laboratory procedures of this practice will have flat, scratch-free surfaces suitable for examination with a microscope using reflected light illumination. The polished surface of briquettes prepared using this practice will contain particles representative of the original gross sample.
Samples prepared by this practice are used for microscopical determination of the textural components in coke (see Test Method D 5061
Scope
1.1 This practice covers laboratory procedures for the preparation of granular samples of coke for examination with a reflected light microscope. The samples prepared are used for identifying and quantifying the textural components in coke. This practice does not apply to the preparation of oriented lump specimens of coke for structural analysis.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety problems, 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.
