Rubber and plastics hoses and hose assemblies - Terminology GB/T
3 terms and definitions
The following definitions and definitions of the following definitions and definitions apply to this document in GB/T 7528-2011.
3.1
Length change rate
The length of the hose assembly is changed by the tensile load, expressed as a percentage of its change in value and the initial length.
3.2
ODVariationrate
The change in the outer diameter of the tube of the hose assembly is caused by the tensile load, expressed as a percentage of its change in value and the initial outer diameter.
3.3
Length of permanent deformation rate
The length change rate of the hose assembly when the load is removed for a certain period of time.
3.4
Outer diameter permanent deformation rate ODpermanentvariationrate
The rate of change in the diameter of the tube when the hose assembly is unloaded for a certain period of time after unloading the load.
4 principle
Under the specified conditions, the hose assembly (empty tube) is horizontally stretched on the tensile tester, with one end fixed and the other end connected
The hydraulic device, according to the requirements of the load recording hose assembly in the process of stretching the length of the change, the diameter of the numerical changes, calculated by the formula
To the various tensile properties of the hose assembly. The schematic diagram of the test principle is shown in Fig.
