PRESSURE CYCLE TEST METHOD OF COMPOSITE CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a pressure cycle test method of a composite container, which can evaluate proper durability corresponding to an actual use environment.SOLUTION: A pressure cycle test method of a composite container 1 which has a reinforced layer on an outer peripheral side of a metal liner so as to be able to hold a high-pressure gas includes: a first process of filling the composite container 1 with a solution to which a solute is added as a pressure medium; and a second process of repeating a plurality of cycles of pressurization and depressurization performed on the pressure medium filling the composite container 1.SELECTED DRAWING: Figure 2
