Scope

“This Part 15 of this document specifies requirements for unfired pressure vessels and their parts made for hydrogen application in addition to the general requirements for unfired pressure vessels under EN 13445-1:2021, EN 13445-2:2021, EN 13445-3:2021, EN 13445-4:2021, EN 13445-5:2021, EN 13445-8:2021, EN 13445-10:2021 and EN 13445-11:2023.

This document distinguishes between four services/damage mechanisms, which might exist in combinations:

 Low temperature service;

 Hydrogen Environmental Embrittlement (HEE) or Hydrogen-induced cracking (HIC);

 High Temperature Hydrogen Attack (HTHA);

 Hydrogen service with cyclic loads (fatigue).

This document does not cover corrosion such as electro-chemical corrosion of metals under participation of hydrogen (e.g. sour gas).”

Purpose

Creation of a specific Part 15 of the EN 13445 series concerning additional requirements for hydrogen applications
