Paragraph 3 Overpressure protection for the low pressure systemF1

The compressed hydrogen storage system downstream of a pressure regulator must be protected against overpressure.

Use of an overpressure protection device, including a pressure relief device, is sufficient to meet the requirement in sub-paragraph (1).

The set pressure of an overpressure protection device must be lower than or equal to the maximum allowable working pressure for the appropriate section of the compressed hydrogen storage system.
