document specifies health and safety requirements, as well as some functional and performance requirements for air conditioning equipment intended to be used for all aircraft types commonly in service in civil air transport The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical and practical air conditioning equipment Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk assessment and thorough service evaluation have shown alternative methods or conditions to be satisfactory This document is a Type C standard as stated in EN 1070:1998 The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document When provisions of this type C standard are different from those, which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard EN 12312-17:2004 (E) Scope This document specifies the technical requirements to minimise the hazards listed in Clause which can arise during the commissioning, operation and maintenance of specific air conditioning equipment for aircraft ground support, when carried out in accordance with the specifications given by the manufacturer or his authorised representative It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies This document is not dealing with the hazards of air conditioning machinery itself, but with the equipment for the specific application of such machinery as aircraft ground support equipment This document applies to all types of moveable air conditioning equipment with evaporators for cooling, heating and ventilating the interior of civil aircraft from outside (ground air conditioning) Examples see Annex A It also applies to air conditioning units and accessories, e.g hoses, couplers, mounted on moveable parts of passenger boarding bridges and/or moveable parts of fixed centralized aircraft air conditioning equipment, whether passenger boarding bridge mounted or ramp integrated This document does not establish requirements for noise and vibration Noise and vibration are dealt with respectively in prEN 1915-4 and prEN 1915-3 This document is not dealing with hazards in respect to a standard automotive chassis and the traffic on the apron This Part of EN 12312 is not applicable to air conditioning equipment, which is manufactured before the date of publication of this standard by CEN Normative references The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the
