Quality Assurance inspects the hose assembly before it is proof tested at the Assembly Validation Test Rig. The pressure test of hose assemblies is performed 100%. At the end of testing, Quality Assurance issues the certificate of conformity which is attached to each hose assembly.
To perform proof pressure testing on the whole HELIX® hose assemblies Transfer Oil has installed a 6000 bar (87000 psi) proof pressure test stand. This machine is able to pressurize assembled hoses with a programmable pressure curve.

In this section you can search for a specific EN 10204 - 3.1 certificate by simply filling Part number, batch number and serial number of your hose assembly. All data are engraved on the ferrule.
