ASTM D97

ASTM D97 is the Standard Test Method for Pour Point of Petroleum Products, providing a recognized way to evaluate the lowest temperature at which a petroleum product will still flow under prescribed conditions. This standard is important for product comparison, specification compliance, and routine quality control because pour point behavior can affect handling, storage, and low-temperature performance. ASTM D97 helps buyers, laboratories, and producers use a consistent test method when assessing petroleum products.

Overview of ASTM D97

The ASTM D97 standard defines a test method focused on determining the pour point of petroleum products. In practical terms, it provides a controlled procedure for observing when a sample no longer flows as temperature decreases. That makes it a useful technical document for laboratories and specification-driven workflows that need consistent, repeatable results. Because pour point is a key low-temperature property, the standard supports product evaluation and comparison in a way that is widely understood across petroleum testing.

Common use cases of ASTM D97

ASTM D97 is commonly used in testing petroleum products where low-temperature flow behavior matters. It is often relevant for laboratory quality control, incoming material review, and product release testing. The standard may also be used when comparing batches, verifying conformity to purchasing requirements, or supporting technical documentation for fuels, oils, and related petroleum materials. In these settings, the method helps provide a consistent basis for assessing pour point performance.

Benefits of using ASTM D97

Using ASTM D97 supports consistent testing and clearer product evaluation by giving laboratories a standard method to follow. That consistency can improve comparability between suppliers, reduce ambiguity in procurement, and strengthen compliance with specification requirements. It also helps organizations manage risk tied to low-temperature handling and storage by providing a recognized measure of pour point. For quality control programs, ASTM D97 offers a practical reference for repeatable, specification-oriented testing.
