This report describes research to evaluate the life cycle durability testing requirements for high pressure hydrogen containers set forth in the Global Technical Regulation (GTR) No. 13 for hydrogen and fuel cell vehicles. NHTSA is considering adopting the GTR requirements into a Federal Motor Vehicle Safety Standard. However, the GTR lacks detail and contains inconsistencies that can only be resolved through development and evaluation of laboratory test procedures. NHTSA contracted Powertech Labs, which is equipped to conduct the specialized hydrogen container assembly testing required in the GTR, to develop detailed test procedures and generate test data to confirm the feasibility of conducting the proposed test sequences. These tests consist of a series of hydraulic and pneumatic pressure cycling and flaw tolerance tests meant to simulate a 15-year service life. Hydrogen containers from three manufacturers were subjected to the tests. Setup diagrams, equipment, procedures, instrumentation, results, and observations were documented.
