General requirements for hydrogen components and systems
Article 5
Manufacturers shall ensure that:
1. hydrogen components and systems function in a correct and safe way and reliably withstand electrical, mechanical, thermal and chemical operating conditions without leaking or visibly deforming;
2. hydrogen systems are protected against over-pressurisation;
3. the materials used for those parts of the hydrogen components and systems which are to be in direct contact with hydrogen are compatible with hydrogen;
4. hydrogen components and systems reliably withstand expected temperatures and pressures during their expected lifetime;
5. hydrogen components and systems reliably withstand the range of operating temperatures laid down in the implementing measures;
6. hydrogen components are marked in accordance with the implementing measures;
7. hydrogen components with directional flow have the flow direction clearly indicated;
8. hydrogen components and systems are designed in such a way that they can be installed in accordance with the requirements of Annex VI.
