This European Standard shall be given the status of a national standard, either by publication of an identical text or by e
24、ndorsement, at the latest by December 2006, and conflicting national standards shall be withdrawn at the latest by December 2006. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of Di

EN 14750-1:2006 (E) 5 Introduction The object
30、 of this European Standard is to establish common comfort parameters for the European railways. It also specifies the performance of the air-conditioning installations. If necessary, the revised requirements due to the operating constraints of the vehicle will be detailed in the contractual specific
31、ation. This European Standard applies if there is no particular clause in the contractual specification. EN 14750-1:2006 (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 system
32、s. This European Standard excludes main line vehicles and driving cabs which are considered in separate European Standards. This European Standard specifies comfort parameters for compartment or saloon (single level or double-decker). These comfort parameters apply in a similar way to the areas rese
33、rved for train staff, with the exception of the catering service areas. The conditions under which the physical parameters mentioned in this European Standard shall be measured are defined in EN 14750-2. 2 Normative references The following referenced documents are indispensable for the application
34、of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
