ASTM D6796

ASTM D6796 is the standard practice for producing coal, coke, and coal combustion samples for interlaboratory studies. It provides a technical framework for preparing representative samples that can be shared across multiple laboratories, helping support consistent comparisons of test results. By addressing sample production for collaborative studies, the standard matters for organizations that need dependable material preparation, reproducible data, and a common basis for evaluating laboratory performance.

What is ASTM D6796?

ASTM D6796 describes a practice for producing samples of coal, coke, and coal combustion materials intended for interlaboratory studies. Its focus is on the sample preparation step, which is critical when different laboratories must test materials under comparable conditions. The standard helps establish a more consistent approach to creating study samples so results can be compared with greater confidence. As an ASTM standard, it supports technical coordination, quality control, and reliable data generation in collaborative testing programs.

Where is ASTM D6796 used?

This practice is commonly used in laboratory and testing environments that conduct interlaboratory studies on coal, coke, and coal combustion samples. It is relevant wherever sample preparation must be controlled so multiple labs can evaluate the same material set in a comparable way. Typical use may include testing programs, method evaluations, round-robin studies, and quality assurance workflows tied to solid fuel and combustion-related materials. ASTM D6796 helps align sample production with study objectives and expected test comparability.

Why is ASTM D6796 important?

ASTM D6796 is important because interlaboratory studies depend on samples that are prepared in a consistent and defensible manner. When sample production varies, test results can be harder to compare and less useful for method assessment or quality review. This practice supports better reproducibility, clearer data interpretation, and more dependable study outcomes. For organizations managing coal, coke, or combustion material testing, it can help reduce uncertainty and improve confidence in collaborative laboratory results.
