Rubber seals for refrigeration systems undergo various tests to evaluate their mechanical properties and suitability. These tests include physical performance testing, chemical resistance testing, temperature resistance testing, expansion performance testing, seal performance testing, contact stress testing, damage and leakage testing, and contact deformation measurement. Physical properties like hardness, density, tensile strength, and tear strength are evaluated. Chemical resistance tests assess the seal’s stability and durability in specific chemicals. Temperature resistance testing ensures the seal maintains performance under extreme temperatures. Expansion performance tests simulate expansion behavior under real working conditions. Damage and leakage testing uses infrared thermal imaging and digital image correlation technology.
