ASTM D293/D293M is the ASTM standard titled Standard Test Method for the Sieve Analysis of Coke, and it provides a structured way to assess coke particle size distribution. This matters because sieve analysis helps users compare material consistency, support quality control, and better understand how coke may behave in handling or use. As a technical document, ASTM D293/D293M is relevant for laboratories, producers, and buyers that need a common testing reference.

ASTM D293/D293M standard overview

This standard focuses on the sieve analysis method for coke, using standardized screening to separate material by particle size. The dual designation indicates availability in inch-pound and SI units, which is useful for organizations working across measurement systems. By defining a common test method, the document helps support repeatable results and more consistent reporting. ASTM D293/D293M is especially useful when technical decisions depend on comparing coke gradation from one sample to another.

Where is ASTM D293/D293M used?

ASTM D293/D293M is commonly used in settings where coke is received, sampled, tested, or specified for quality purposes. It may be used by laboratories, inspection teams, producers, and purchasers that need a dependable sieve analysis procedure for routine evaluation. The standard is also relevant in workflows that require documented particle size data before acceptance, shipment, or further processing. In these contexts, the method helps keep testing and reporting aligned.

Practical importance of ASTM D293/D293M

The practical value of ASTM D293/D293M lies in its role as a consistent test method for size-based evaluation. When coke is tested using the same approach, results are easier to compare across lots, suppliers, and time periods. That supports compliance, procurement decisions, and quality control programs. It can also help reduce miscommunication by giving all parties a shared basis for reporting sieve analysis results and interpreting material consistency.
