Tensile test of large rubber hose assembly Caution - Personnel using this standard should be familiar with formal laboratory procedures. This standard is not intended to involve the use of this standard may occur All the security issues. It is the user's responsibility to develop appropriate safety and health regimes and to ensure compliance with national regulations.

1 Scope

This standard specifies a test method for tensile load deformation of a large rubber hose assembly with a nominal diameter of 150 or more. This standard is applicable to the tensile test of large rubber hose assemblies with flanges at both ends.

2 normative reference documents

The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. 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.
