Draft Scope/Description:

1.1 Inclusions

This Standard specifies the minimum testing requirements for verifying the fuelling protocols specified in SAE J2601 and the communications protocols in SAE J2799.


This Standard applies to dispensing systems, referred to as dispensers in this Standard, designed to fill vehicle storage systems in accordance with SAE J2601.


Note: The SAE J2601 fuelling protocols target rapid fills while respecting temperature, pressure, and fuel density safety limits.


Note: This Standard is a minimum requirement. Manufacturers can take additional safety precautions.


This Standard was developed for and is intended to be used with the specific editions of SAE J2601 and SAE J2799 as referenced in Clause 2.


For dispensers with the capability for communications with the vehicle, these test methods include the approach to confirm the requirements specified in SAE J2799 and SAE J2601.


Newly manufactured dispensers should be tested according to this Standard prior to initial operation of the dispenser for fuelling vehicles. This Standard is also intended to provide test methods for validation of existing dispensers.


Unless otherwise specified, the requirements in this Standard apply to the verification of SAE J2601 compliant hydrogen fuelling stations (HFS).


In the case of conflict between this Standard and federal, provincial/territorial, state, or local requirements, the governmental requirements take precedence.


The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.


All references to pressure throughout this Standard are to be considered gauge pressure unless otherwise specified.


In this Standard, “shall” is used to express a requirement, i.e., a provision that the user shall satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
