Standard Test Method for the Sieve Analysis of Coke

This test method determines the size distribution of coke by separating a sample into defined sieve fractions and reporting each fraction as a percentage of the gross sample mass.

ASTM D293/D293M-26 specifies a method for determining the size distribution of coke through sieve analysis. It covers the selection and use of test sieves, sample preparation, sieving procedures, mass measurements, reporting of size fractions, and considerations for precision and bias. The method applies SI and inch-pound units independently and references ASTM D346, ASTM E11, and ASTM E323. Application Scope: Used for laboratory and routine quality testing of coke to determine size fractions and verify conformance with specified percentages retained on designated sieve sizes.
