Hydrogen is an attractive energy carrier that requires high effort for ensuring safety in storage. Therefore, they must undergo a challenging approval process. Relevant standards and regulations for composite cylinders used for on-board storage and for the transport of hydrogen are currently based on deterministic (e.g. ISO 11119-3) or semi-probabilistic (UN GTR No. 13) criteria. This paper analyses the properties of relevant methods with respect to the load cycle strength. Their characteristics are compared with the probabilistic approach of BAM. Based on Monte-Carlo simulations, the available design range (mean value and scatter of strength criteria) of current concepts was analysed. The challenging aspect of very small sample sizes is analysed and evaluated.
