ASTM D2240
Standard Test Method for Rubber Property—Durometer Hardness


ASTM D2240 establishes a standardized test method for measuring the hardness of elastomers, rubbers, and plastic materials using a durometer instrument. The measurement principle relies on the penetration depth of a conical or spherical indenter pressed into the sample surface, yielding a numerical value that indicates material resistance to deformation. Applicable to both finished products and semi-finished articles, the standard defines precise procedures with different scales (Shore A and Shore D) to ensure consistent, reproducible results for industrial quality control and material specification purposes.
