BS EN 12312-8:2005+A1:2009 EN 12312-8:2005+A1:2009 (E) 4 Introduction This European Standard specifies health and safety requirem
24、ents, as well as some functional and performance requirements for maintenance stairs and platforms including a built-in source of power (see Clause 1, Scope) intended for maintenance purposes on all aircraft types commonly in service in civil air transport. The minimum essential criteria are conside
25、red to be of primary importance in providing safe, serviceable, economical and practical maintenance stairs and platforms. Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk assessment and thorough service evaluation have shown alternative
26、 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 are indicated in the scope of this document. When provisions of this type C standar
27、d 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.

28、-8:2005+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, operation and maintenance of maintenance stairs and platforms when carried out in accordance with the specifications given by
29、 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 maintenance and handling agencies. This European Standard applies to:
30、 self-propelled maintenance stairs and platforms; towable maintenance stairs and platforms equipped with powered means, e.g. for height adjustment, stabi-lizers, designed for aircraft maintenance purposes including access to the aircraft (Examples see Annex A). NOTE 1 Powered should be also understo
31、od as manual effort stored in springs or hydraulic accumulators, etc., the danger-ous action of which can be produced or can continue after the manual effort has ceased or directly applied manual effort for lifting or lowering loads. NOTE 2 Those clauses of this European Standard that can apply may
32、also be used as a guideline for the design of towable maintenance stairs and platforms without powered means. This European Standard does not apply to: maintenance docks either fixed to the ground or moveable only for docking procedure. This European Standard does not establish requirements for nois
33、e 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 EN 12312 is not applicable to maintenance stairs and platforms
34、 which are manufactured before the date of publication of this 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 vehi-cles) and EN 1915-4.“ 2 Normative references The following referenced documents are indispensable for the applic
