For the purpose of this standard, the terms and definitions specified in GB/T 24548 as well as the following apply.
3.1
pressure-temperature method
method of calculating hydrogen consumption by measuring the pressure and temperature of gas in high-pressure hydrogen tank before and after test. The hydrogen tank with known internal volume which is able to test temperature and pressure shall be used
3.2
weight analysis method
method of calculating hydrogen consumption by measuring the weight of high-pressure hydrogen tank before and after test. The hydrogen tank used in test shall be applied for weight measurement
3.3
hydrogen flow method
method of measuring the volume or weight of hydrogen consumed by a vehicle through the flowmeter installed on the hydrogen supply pipeline from fuel supply resource outside the vehicle to the vehicle
