Standard Practice for Collection and Preparation of Coke Samples for Laboratory Analysis

Importancia y uso:

4.1 This practice may be used to provide a representative sample of the coke from which it is collected. Because of the possible variability of coke and the wide variety of sampling equipment in use, caution must be exercised in all stages of sampling, from system specifications and equipment procurement to equipment acceptance testing and actually taking the final sample. It shall be noted from where the coke sample is collected and the degree of handling prior to being collected as coke can fracture upon successive handling from its initial removal from the coke oven due to the nature of the fissures that exists in the material. This fracturing can have a substantial impact on testing results for both material sizing and strength.

4.2 This practice also provides procedures for the preparation of an analysis sample of coke from the gross or divided sample. Data obtained from the analysis samples can be used in establishing price, determining acceptability for use in iron and steel industry processes, environmental impacts, as well as for other purposes.

4.3 In addition to complying with the requirements of ISO 13909-5, ISO 13909-6, ISO 13909-8 and ISO 18283, the Annex of this standard practice contains information that shall be considered mandatory. The information in this Annex is presented where it is specific to ASTM standard test methods or not otherwise covered in the governing ISO standards.
