ISO 3386-2
Flexible cellular polymeric materials –Determination of stress-strain characteristics in compression –Part 2: High-density materials


ISO 3386-2 establishes the test method for determining indentation hardness of elastomers and polymeric foams using a sphere indentation technique. This standard applies to elastomeric materials, rubbers, and cellular foams employed in industrial and comfort applications. The test measures the penetration depth of a standardized sphere under controlled load and duration conditions, providing critical data on material stiffness and mechanical properties. Results are essential for quality control and material selection in cushioning applications, thermal insulation, and high-compressibility components.
