Product Code:SAE J2600
Title:Compressed Hydrogen Surface Vehicle Refueling Connection Devices
Issuing Committee:Fuel Cell Standards Committee
Scope: SAE J2600 applies to design, safety and operation verification of Compressed Hydrogen Surface Vehicle (CHSV) refuelling connection devices hereinafter referred to as nozzle and receptacle. CHSV Refuelling nozzles and receptacles shall consist of the following components, as applicable. Alternatives may be used as long as the alternative geometries shall not be interchangeable with the standard geometry specified in this SAE Standard and the standard geometry in Section 6 provides insufficient flow rates: a. Receptacle and protective cap (mounted on vehicle) (see Section 6 and 7); b. Nozzle (see Section 5).This document applies to devices which have Working Pressures of 25 MPa, 35 MPa, 50 MPa or 70 MPa hereinafter referred to in this document as the following (see 9.1c): H25 - 25 MPa at 15 mDC; H35 - 35 MPa at 15 mDC; H50 - 50 MPa at 15 mDC; H70 - 70 MPa at 15 mDC.This document applies to nozzles and receptacles which (1) prevent hydrogen fuelled vehicles from being refuelled by dispenser stations with Working Pressures higher than the vehicle; (2) allow hydrogen vehicles to be refuelled by dispenser stations with Working Pressures equal to or lower than the vehicle fuel system Working Pressure, (3) prevent hydrogen fuelled vehicles from being refuelled by other compressed gases dispensing stations and (4) prevent other gaseous fuelled vehicles from being refuelled by hydrogen dispensing stations.All dimensions used in this document are in metric units [International System of Units (SI)].For the purposes of this document, compressed hydrogen gas should meet the requirements of ISO 14687 Hydrogen fuel - Product specification.All references to pressures (MPa) throughout this document are to be considered gauge pressures unless otherwise specified. All test procedures listed in this document are design verification test procedures unless otherwise noted. All products must pass all tests to be considered to have met this design standard.
