22、n, Switzerland and United Kingdom. BS EN 12312-20:2005+A1:20094 Introduction This European Standard specifies health and safety requirements, as well as some functional and performance requirements for ground power equipment intended for the electrical supply for aircraft to be used on all aircraft
23、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 ground power equipment. Deviations from the recommended criteria should occur only after careful consideration, extens
24、ive testing, risk assessment and thorough service evaluation have shown alternative methods or conditions to be satisfactory. This European Standard is a Type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered ar
25、e indicated in the scope of this European Standard. 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
26、built according to the provisions of this type C standard. EN 12312-20:2005+A1:2009 (E) BS EN 12312-20:2005+A1:2009EN 12312-20:2005+A1:2009 (E) 5 1 Scope This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, o
27、peration and maintenance of ground power equipment, 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 equipmen
28、t (GSE) manufacturers as well as airlines and service companies. This European Standard applies to: ground power units either self-propelled or towable (Examples see Annex A); ground power equipment when mounted on other GSE; ground power accessories intended for ground power equipment (including ac
29、cessories for fixed equipment). This European Standard does not apply to: the electrical characteristics of the supply, the type of power supply system and related measures against contact; any electrical supply system not intended for aircraft use; the on-board electrical system of the aircraft. Th
30、is European Standard does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3. This European Standard does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron. This Part of E
31、N 12312 is not applicable to ground power equipment which is manufactured before the date of publication of this European Standard by CEN. !This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.“ 2 Normative references The follo
