is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. b s t r a c tImprovements in the characterisation of materials used in pipes, tubes or vessels rely on the development of tests on cylindrical samples in order to be consistent with the real manufacturing process. Existing devices are unable to reach the pressure limits required to test high pressure hydrogen storage tanks. We therefore propose an original test device based on a conical fitting system. First, the operational principle and the pressure measurement technique are presented. Next, the choice of apparatus design parameters according to test requirements is discussed. In addition, the device's capabilities are illustrated on a 39 mm thick CFRP ring test including Digital Image Correlation measurements.
