cell electric vehicles.

This Standard is applicable to fuel cell electric vehicles which use compressed

hydrogen as fuel, of which the working pressure does not exceed 35 MPa when

it works at 15°C of ambient temperature.

Specifications

3 Terms and definitions

The terms and definitions defined in GB/T 24548 apply to this document.

4 Test conditions

4.1 Vehicle conditions

4.2 Environmental conditions

4.2.1 During the test, the atmospheric pressure shall not be less than 91 kPa;

the temperature shall be at 5°C~35°C; the relative humidity shall be less than

95%; the test site shall be remained dry.

5 Test equipment and instruments

The test equipment and instruments shall be detected, maintained and

calibrated according to manufacturer's requirements.

6 Test methods

6.1 General

6.1.1 Hydrogen storage vessel and piping
6.1.1.1 Check if the hydrogen system piping installation and alignment are

away from heat, electrical appliances, storage batteries or any place which may

generate electric arc. Check if high pressure piping and components are reliably

grounded.

6.1.1.4 Check if the metal parts of supporting and securing pipeline are in

contact with the piping, except the welding BETWEEN the piping AND

supporter and fastener.

6.1.1.5 Check the neat arrangement of rigid pipeline. Check if the rigid

pipeline is in contact with or rub with the adjacent parts. Check if the pipeline

has seismic resistance and measures to eliminate the influence of thermal

expansion and contraction. For bending pipes, measure its radius of the axis of

curvature. Measure the interval distance between supporting points of piping.

6.1.2 Hydrogen leakage
6.1.2.1 Hydrogen leakage. fill the hydrogen storage vessel in the test vehicle

to 100% of working pressure, and put it in a hermetic space for 8 h according

to provisions. Measure the hydrogen permeation rate.

6.1.3 Refuelling receptacle
6.1.3.1 Check if refuelling receptacle shape and size comply with the

requirements of GB/T 26779-2011.Measure the installation place and height of

refuelling receptacle.

6.1.3.2 If there are exposed electrical terminals, electrical switches and

ignition source around the refuelling receptacle, measure the distance between

them. Check if it complies with the provisions of GB/T 26990-2011.

6.1.4 Hydrogen emission

When pressure relief valve releases hydrogen, check if the position, direction

of exhaust gas flow are far away from people, power and fire source.
