Astm D61821 Pdf

This test method describes the procedures to determine [primary property, e.g., tensile strength, flexural modulus, permeability, etc.] of [material, e.g., polymer, composite, coating] under specified conditions. The method applies to laboratory specimens prepared under controlled temperature and humidity and is intended for routine quality control and comparative testing rather than absolute material characterization.
