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.
