This standard specifies methods for determining the vacuum resistance of rubber and plastic hoses and hose assemblies. Vacuum resistance is a key indicator for measuring the Stability and durability of hoses in a vacuum environment, especially in applications involving the transport of liquids or gases. The standard assesses the deformation, breakage or failure of hoses under vacuum conditions by specifying test procedures and equipment requirements. The test results help to determine whether hoses can maintain performance for a long time under a specific working environment, ensuring their safety and Reliability in industrial, automotive, chemical and other fields.
