SAE J 343 standard test including Dimensional Check Test, Proof Test, Change in Length Test, Burst Test, Cold Bend Test, Impulse Test etc.


Impulse Test

The impulse test has two categories:

High pressure, which covers pressures higher than 3 MPa  

Low pressure, which covers 1 .5 to 3 MPa Test four unwaged hose assemblies with end fittings, which have been attached for not more than 30 days. Where the individual standard requires, also test aged hose assemblies.


Calculate the free (exposed) length of hose under test, shown on Figure 1 , as follows:
