BS ISO 19882:2018

This document establishes minimum requirements for pressure relief devices intended for use on hydrogen fuelled vehicle fuel containers that comply with ISO 19881, IEC 62282‑4‑101, ANSI HGV 2, CSA B51 Part 2, EC79/EU406, SAE J2579, or the UN GTR No. 13.

This document establishes minimum requirements for pressure relief devices intended for use on hydrogen fuelled vehicle fuel containers that comply with ISO19881, IEC62282‑4‑101, ANSIHGV2, CSAB51 Part2, EC79/EU406, SAEJ2579, or the UNGTRNo.13.

The scope of this document is limited to thermally activated pressure relief devices installed on fuel containers used with fuel cell grade hydrogen according to SAEJ2719 or ISO14687 for fuel cell land vehicles, and GradeA or better hydrogen according to ISO14687 for internal combustion engine land vehicles. This document also contains requirements for thermally activated pressure relief devices acceptable for use on-board light duty vehicles, heavy duty vehicles and industrial powered trucks such as forklifts and other material handling vehicles, as it pertains to UN GTR No. 13.

Pressure relief devices designed to comply with this document are intended to be used with high quality hydrogen fuel such as fuel complying with SAEJ2719 or ISO14687 Type1 GradeD.

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

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

Documents which apply to hydrogen fuel vehicles and hydrogen fuel subsystems include IEC62282‑4‑101, SAEJ2578 and SAEJ2579.

AnnexA presents an informative record of recommended fuel container, fuel storage subsystem and vehicle level requirements. The statements in AnnexA are intended as recommendations for consideration of inclusion by the organizations and committees developing standards on these sub system and vehicle level standards.

AnnexB presents a rationale for the design qualification tests in this document.
