ASTM E1520

ASTM E1520 is the ASTM standard for the Standard Test Method for Particle Counts Per Pound of Granular Carriers and Dry-Applied Granular Formulations. It provides a technical basis for measuring particle counts in these materials, helping users compare products more consistently and support quality control activities. For buyers, laboratories, and manufacturers, this standard can be useful when evaluating granule-based materials where particle count is an important performance or specification factor.

What is ASTM E1520?

This standard defines a test method focused on counting particles per pound in granular carriers and dry-applied granular formulations. In practical terms, ASTM E1520 helps establish a repeatable way to assess how many particles are present in a given mass of material. That can support product characterization, lot-to-lot comparison, and internal acceptance testing. As a technical document, it is mainly relevant where particle count is used to describe or verify the consistency of a granular product.

Where is ASTM E1520 used?

ASTM E1520 is commonly used in settings that handle granular carriers or dry-applied granular formulations, especially where material uniformity matters. It may be applied in testing labs, manufacturing quality programs, and procurement reviews for granulated products. The standard is most relevant to workflows that need a defined method for measuring particle count per unit weight, rather than relying on informal observation or nonstandard practices. It supports consistent evaluation during production and incoming material checks.

Why is ASTM E1520 important?

This standard matters because particle count can influence how a granular material is described, compared, and controlled. Using a recognized ASTM method can help reduce variation in testing results and improve confidence in product evaluation. ASTM E1520 also supports clearer communication between suppliers and customers when particle count is part of the specification or acceptance process. For quality-focused operations, it can be a practical tool for compliance, repeatability, and risk reduction.
