Temporary interim requirement for performance of fittings for compressed hydrogen gas and hydrogen rich gas mixtures
This temporary interim requirement (TIR) specifies uniform methods for testing and evaluating the performance of fittings (including fittings, connectors and stud ends for ports) for use with compressed hydrogen gas and hydrogen rich gas mixtures. This TIR does not address quick action couplings, (i.e., quick connects), flanges; or welded joints. This TIR does not address special requirements for liquid and slush hydrogen.
