EN 14750-2:2006 (E) 5 Introduction The object of this European Standard is to 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 operati
27、ng constraints of the vehicle will be detailed in the contractual specification. This European Standard applies if there is no particular 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 an
28、d tramway vehicles equipped with cooling and/or heating/ventilation systems. This European Standard excludes main line vehicles and driving cabs which are considered in separate European Standards. This European Standard specifies the comfort parameter measurement methods for compartment or saloon (
29、single level or double-decker). The comfort parameters and their tolerances cited in this European Standard are defined in EN 14750-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

It does not aim to verify the comfort parameters and performance of the system. It can be done in a workshop or
33、at a yard. TL2 is a full level test to verify the comfort parameters and the performance of the system. This test shall be performed in a climatic chamber or in appropriate environment. The test classification shall be detailed in the contractual specification. In the absence of any specified contra
34、ctual detail, the full level of testing (TL2) shall apply. If not stated otherwise, the following requirements apply to both TL1 and TL2. 2) To be purchased from: International Commission of Illumination, CIE Central Bureau, Kegelgasse 27, A-1030 Wien.

35、ns It is advised that preliminary tests are carried out to verify the electrical and electronic assemblies, the functional logic of 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. The
36、se verifications should be conducted before proceeding to the comfort test. 6 Comfort tests 6.1 Air movement 6.1.1 General remarks The tests shall be carried out under the following conditions: vehicle stationary and protected from bad weather; altitude Tem 0 to 15 0 100 Normal TL 121 Regulation Tem
