EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 11114-4 testing. This standard specifies test methods for characterizing steels suitable for use in the manufacture of gas cylinders for hydrogen and hydrogen-containing embrittlement gases and the evaluation of the results obtained from these tests.
This document applies to seamless steel gas cylinders only. The requirements of this document do not apply if at least one of the following conditions is met for the intended gas service.
The working pressure of the filled embrittlement gas is less than 20% of the test pressure of the cylinder. The partial pressure of the filled embrittlement gas of a gas mixture is less than 5 MPa (50 bar) in the case of hydrogen and other embrittlement gases except hydrogen sulfide and methyl mercaptan. In such cases, the partial pressure should not exceed 0,25 MPa (2,5 bar).
In such cases, it is possible to design the cylinder for ordinary (non-fragile) gases.
EUROLAB assists manufacturers with ISO 11114-4 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories.
