conditions for urban operation as specified in GB 18352.3-2005, with the test duration
of 45 min; record data as required in 5.1.1.4.
5.3 Frosting test method for air-conditioning system
5.3.1 Test participants (at least 2) enter the vehicle; set the temperature switch to the
maximum refrigeration mode position, the air circulation switch at the outer circulation
position and the air volume switch at the maximum gear;
5.3.2 During the whole test process, observe from time to time whether the
temperature at the air outlet rises; if it rises, stop the vehicle rapidly and check whether
frost forms on evaporator and low pressure pipe lines.
5.4 Pressure test method for air-conditioning refrigeration system
5.4.1 Run the vehicle for preheating.
6 Recording of measured data
All data measured shall be recorded in log sheets which is as specified in or similar to
those specified in Annex C.
