Compression Strength

Compression strength refers to a material's ability to resist failure under compressive forces, typically expressed as the maximum pressure per unit area, measured in MPa or psi. In foreign trade, this term is commonly found in specifications for building materials, metals, plastics, packaging, and other products, and is a key indicator for buyers to evaluate product quality and suitability. Usage scenarios include contract technical annexes, quality inspection reports, product manuals, and letter of credit requirements. Note: Different national or industry standards (such as ASTM, ISO, GB) use different test methods, which may lead to numerical differences, so the standard must be specified; also distinguish compression strength from tensile strength and flexural strength to avoid confusion. In addition, carton compression strength is often required in packaging and transportation to ensure stacking safety. Foreign trade practitioners should specify the test standard, sampling method, and tolerance in the contract to prevent claims arising from non-conforming indicators.
