ActiveRubber and plastics hoses and tubing—Textile-reinforced types—Sub-ambient temperature crush test
橡胶和塑料软管及非增强软管 织物增强型 低温压扁试验
Application Summary AI generated
This standard specifies a test method for evaluating the resistance of textile-reinforced rubber and plastics hoses to crushing at sub-ambient temperatures. It is applied in quality control and product validation for flexible hose assemblies used in fluid systems, such as hydraulic, pneumatic, or fuel lines, that must maintain structural integrity under cold environmental conditions. The test ensures hoses do not collapse or permanently deform when subjected to a specified compressive load at low temperatures, verifying their suitability for use in cold climates or refrigerated systems.
