ASTM D1622 is the standard test method for determining the apparent density of rigid cellular plastics. It is used to measure a key physical property that helps characterize these materials for specification, comparison, and quality control. Because apparent density can influence how a rigid cellular plastic is selected and evaluated, this ASTM standard provides a consistent technical basis for testing and reporting results in a controlled, repeatable way.

Overview of ASTM D1622

ASTM D1622 focuses on a practical measurement used in the evaluation of rigid cellular plastics: apparent density. The standard supports laboratory and production testing by defining a recognized method for obtaining comparable results across materials and batches. In procurement, engineering, and manufacturing workflows, it helps users reference the same test approach when assessing product consistency, material performance, or conformance to requirements. As an ASTM standard, it is commonly used as a technical document for routine verification and standardized reporting.

Common use cases of ASTM D1622

ASTM D1622 is commonly used when rigid cellular plastics need to be checked for density-related properties during product development, incoming inspection, or quality control. It is especially relevant for manufacturers, testing labs, and specifiers working with foam or other rigid cellular plastic materials where apparent density is an important acceptance or comparison factor. The method may also support product qualification, lot-to-lot consistency checks, and technical documentation for materials intended for engineering or commercial applications.

Benefits of using ASTM D1622

Using ASTM D1622 helps create consistency in how apparent density is measured and reported for rigid cellular plastics. That consistency supports clearer communication between suppliers, buyers, and testing organizations, which can reduce ambiguity in specifications and procurement. It also helps with repeatable quality control and product evaluation by providing a recognized reference method. For teams managing material compliance or performance verification, the standard can reduce testing uncertainty and improve confidence in comparison results.
