SAE J2601 establishes the protocol and process limits for hydrogen fueling of light duty vehicles. These process limits (including fuel temperature, the maximum fuel flow rate, and rate of pressure increase and end pressure) are affected by factors such as ambient temperature, fuel delivery temperature and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J2601-2014 establishes standard fueling protocols based on a look-up table approach with performance targets. The current standard is table-based and provides concise performance targets for both communications and non-communications fueling as described in Sections 7 through 10. An important factor in the performance of hydrogen fueling is the station’s dispensing equipment cooling capability and the resultant fuel delivery temperature “T” rating. SAE J2601 has a reference fueling target of 3 minutes with 95-100% SOC (with communications) with a T40 rated dispenser as specified in section 6.1.
This method is currently under development in the E-34C Lubricating Characteristics subcommittee as a technique to predict the micropitting performance of 5 cSt turbine oils.

Once the specimens have been manufactured, a small round robin is planned to look at repeatability and reproducibility.
