Gaseous hydrogen — Thermally activated pressure relief devices for compressed hydrogen vehicle fuel containers

This document specifies minimum requirements for pressure relief devices intended for use on hydrogen fuelled vehicle fuel containers that comply with ISO 19881, IEC 62282-4-101, CSA/ANSI HGV 2, EC79/EU406, SAE J2579, UN ECE R134, or the UN GTR No. 13.

The applicability of this document is limited to thermally activated pressure relief devices installed on fuel containers containing gaseous hydrogen according to ISO 14687 for fuel cell and internal combustion land vehicles. This document specifies requirements for thermally activated pressure relief devices acceptable for use on-board the following types of land vehicles:

—          light-duty vehicles;

—          heavy-duty vehicles;

—          industrial powered trucks, such as forklifts and other material handling vehicles.

Requirements for other types of land vehicles such as rail, off-road, etc., can be derived with due consideration of appropriate service conditions.

This document does not apply to reseating, resealing, or pressure-activated devices.

Pressure relief devices can be of any design or manufacturing method that meets the requirements of this document.
