Product Code:SAE J2572
Title:Recommended Practice for Measuring Fuel Consumption and Range of Fuel Cell and Hybrid Fuel Cell Vehicles Fuelled by Compressed Gaseous Hydrogen
Issuing Committee:Fuel Cell Standards Committee
Scope:This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, road and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis Dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing. Communication between vehicle manufacturer and the governing authority is essential when starting official manufacturer in-house and official government confirmatory testing that incorporates this practice.Product Code:SAE AMS4922
Title:Titanium Alloy, Seamless Hydraulic Tubing, 15V - 3.0Cr - 3.0Al - 3.0Sn, Cold Worked and Precipitation Heat Treated
Issuing Committee:Ams G Titanium And Refractory Metals Committee
Scope:This specification covers a titanium alloy in the form of seamless tubing.
