10. NON-STANDARD, DEVELOPMENT HYDROGEN FUELING PROTOCOLS

All dispensers which are certified to SAE J2601 shall have the capability to fuel vehicles using one or more of the standard fueling protocols defined herein. Public dispensers may fuel vehicles using development fueling protocols as means for field validation after engineering due diligence is performed. However, they shall not use them as the primary fueling protocol and shall have a method of ensuring an unattended public user cannot access them without authorization from the station provider and vehicle OEM. The use of authorization systems, such as access codes or authorization cards, which can be accessed by public users, have been problematic in the past. The use of development fueling protocols should be done responsibly and it is ultimately the responsibility of the station provider to ensure that a development fueling protocol is only utilized for the intended vehicle(s) and user(s).

The purpose of utilizing a non-standard fueling protocol in a demonstration or in a development capacity is to bring data and real world experience (to verify the protocol's capability to operate within the constraints of Section 6), back to the SAE Fuel Cell Standards Interface Task Force for future incorporation into the SAE J2601 standard.
