CNH 82032291 Standard Test for Mounting Properties of High Pressure Hoses

EUROLAB laboratory provides testing and compliance services within the scope of the CNH 82032291 standard. Unworn hose assemblies with fixed end connections for no more than 30 days are subjected to a hydrostatic pressure of 5,0% of the specified minimum burst pressure for a period of 5,5 to 70 minutes.

Reduce the fluid pressure to 0Mpa. Reapply 5,0% of the minimum burst hydrostatic pressure for a period of 5,5 to 70 minutes. Reject assemblies that show leaks or malfunctions.

After immersing in ASTM Emergency Standard Practice IRM903 oil for 70 hours at the specified maximum temperature, the volume change of the samples taken from the hose inner tube and cap will be between 0% and 50%.

Instead of test results on hose assemblies, the supplier may issue a certificate of conformity from the hose manufacturer stating that the tests have been carried out and all requirements have passed.

Apply a pulsating pressure of 0,5 to 1,3 Hz internally to the hose and hose assemblies; Record the frequency used. The pressure cycle should be within the shaded area of ​​Figure 1 and should be as close as possible to the curve shown.
