This document outlines the extensive testing and regulatory evaluation of a new pressure vessel design by XPERION for CNG engines. It highlights innovative testing methodologies, including static and cyclic fatigue tests up to 100,000 load cycles, and the development of a new residual strength test methodology. The study also examines gaps in current ECE regulations regarding fire engulfment and burst testing. Findings will support advancements in hydrogen storage and composite containment for vehicle applications.
