ASTM D280 is the ASTM standard that covers test methods for hygroscopic moisture and other matter volatile under the test conditions in pigments. It is relevant when buyers, laboratories, and quality teams need a consistent way to evaluate volatile content in pigment materials. By defining a recognized test approach, this technical document helps support comparison, product control, and more reliable material assessment during procurement and testing.

Purpose of ASTM D280

The purpose of ASTM D280 is to provide standardized test methods for measuring moisture absorbed from the atmosphere, along with other substances that may volatilize during the test. In pigment evaluation, this matters because volatile content can affect reported composition, handling, and test results. The standard helps create a common basis for laboratory work and supports consistent results across different users, equipment, and quality control settings. ASTM D280 is therefore useful wherever pigment properties must be measured in a repeatable, documented way.

Common use cases of ASTM D280

ASTM D280 is commonly used in pigment testing workflows where moisture or other volatile matter may influence measured results. It may be applied during incoming material checks, product qualification, routine quality control, or comparative evaluation between pigment lots. Laboratories and technical teams use it to support consistent reporting and to reduce uncertainty when pigments are reviewed for specification compliance. The standard is especially relevant when accurate interpretation of volatile content is important to the final assessment.

Why ASTM D280 matters

This standard matters because volatile content can change how a pigment is understood, specified, and accepted. Using ASTM D280 helps improve consistency in test results, which supports compliance decisions, procurement review, and internal quality control. It can also reduce risk when comparing materials from different sources or batches. For organizations working with pigment products, a recognized ASTM method provides a clearer technical basis for evaluation and helps keep testing practices aligned across teams and suppliers.
