Date:Jul 09, 2019

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.
