About This Item
ASTM D6093 is a test method for determining percent volume nonvolatile matter in clear or pigmented coatings using a helium gas pycnometer. It helps users evaluate coating composition by measuring the nonvolatile portion on a volume basis, which is useful for formulation work, product comparison, and quality control. By focusing on a defined measurement approach, this ASTM standard supports more consistent testing and clearer communication of coating performance data.
Purpose of ASTM D6093
The purpose of ASTM D6093 is to provide a standardized way to measure percent volume nonvolatile matter in coatings with a helium gas pycnometer. This is important because nonvolatile content can affect how a coating performs, how it is formulated, and how it is compared against other products. The method gives manufacturers, laboratories, and specifiers a consistent technical basis for evaluating clear or pigmented coatings using a controlled test procedure.
Common use cases of ASTM D6093
This standard is commonly used in coating laboratories, research and development settings, and quality control workflows where accurate nonvolatile content measurement is needed. It may support product development, batch comparison, incoming material checks, and specification verification for clear or pigmented coatings. ASTM D6093 is also useful when a helium gas pycnometer is part of the test equipment and a volume-based result is needed for technical reporting or internal review.
Why ASTM D6093 matters
ASTM D6093 matters because it helps reduce variation in how nonvolatile matter is measured and reported. That consistency supports better compliance decisions, more reliable procurement comparisons, and stronger product evaluation across different lots or formulations. For coatings work, having a recognized ASTM standard can also improve confidence in test results, especially when measurements are used to support specifications, performance checks, or quality control documentation.
