GB/T 7129-2001
ActiveRubber or plastics hoses--Determinationof volumetric expansion
橡胶或塑料软管 容积膨胀的测定
Application Summary AI generated
This standard specifies a test method for measuring the volumetric expansion of rubber or plastics hoses under internal hydrostatic pressure. It is applied in the manufacturing and quality control of hydraulic and pneumatic hose assemblies, particularly for verifying dimensional stability and performance in fluid power systems. The standard ensures hoses meet design tolerances for expansion, which is critical for maintaining system pressure and preventing failure in industrial, automotive, and aerospace applications.
