ČSN EN 17533

This document specifies the requirements for the design, manufacture and testing of cylinders, tubes and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material. These are intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 1 100 bar, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4), hereafter referred to as pressure vessels. NOTE - Additional requirements with regard to assemblies (manifolded cylinders and tubes and other pressure vessels) are not covered by this document. This document is not applicable to Type 2 and 3 vessels with welded liners. This document is not applicable to pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications. This document is not applicable to external piping which can be designed according to recognized standards.
