EN 14750-2:2006 (E) 5 Introduction The object of this European Standard is t
27、o establish programmes and test methods to verify the air conditioning installations as described in EN 14750-1. If necessary, the revised requirements due to the operating constraints of the vehicle will be detailed in the contractual specification. This European Standard applies if there is no par
28、ticular clause in the contractual specification. EN 14750-2:2006 (E) 6 1 Scope This European Standard is applicable to suburban and/or regional vehicles and also metro and tramway vehicles equipped with cooling and/or heating/ventilation systems. This European Standard excludes main line vehicles an
29、d driving cabs which are considered in separate European Standards. This European Standard specifies the comfort parameter measurement methods for compartment or saloon (single level or double-decker). The comfort parameters and their tolerances cited in this European Standard are defined in EN 1475

TL1 is a simplified level that gives prin
33、ciple information about the functionality of the system. It does not aim to verify the comfort parameters and performance of the system. It can be done in a workshop or at a yard. TL2 is a full level test to verify the comfort parameters and the performance of the system. This test shall be performe
34、d in a climatic chamber or in appropriate environment. The test classification shall be detailed in the contractual specification. In the absence of any specified contractual detail, the full level of testing (TL2) shall apply. If not stated otherwise, the following requirements apply to both TL1 an

EN 14750-2:2006 (E) 7 5 Preliminary verifications It is advised that preliminary tests are carried out to verify the electrical and electronic assemblies, the functional logic of
36、 the control system, the air tightness of the air distribution system, the water tightness of the vehicle and the thermal capacity of the air conditioning equipment. These verifications should be conducted before proceeding to the comfort test. 6 Comfort tests 6.1 Air movement 6.1.1 General remarks
