Ehdotuksen soveltamisala:
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, CSA/ANSI HGV 2, EC79/EU406, SAE J2579, UN ECE R134, or the UN GTR No. 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 SAE J2719 or ISO 14687 for fuel cell land vehicles, and Grade A or better hydrogen according to ISO 14687 for internal combustion engine land vehicles. This document contains requirements for thermally activated pressure relief devices acceptable for use on-board the following types of land vehicles: light-duty vehicles, heavy-duty vehicles and industrial powered trucks, such as forklifts and other material handling vehicles. Requirements for other types of land vehicles such as rail, off-road, etc., may be derived with due consideration of appropriate service conditions. 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 IEC 62282- 4-101, SAE J2578, SAE J2579, UN ECE R134, or UN GTR No. 13. Annex A presents an informative record of recommended fuel container, fuel storage subsystem and vehicle level requirements. The statements in Annex A are intended as recommendations for consideration of inclusion by the organizations and committees developing standards on these sub system and vehicle level standards. Annex B presents a rationale for the design qualification tests in this document.
