33、2312-8:2018 (E) 5 Introduction This European Standard specifies health and safety requirements, as well as some functional and performance requirements for maintenance stairs and platforms including a built-in source of power (see Scope, Clause 1) intended for maintenance purposes on all aircraft ty
34、pes 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 maintenance or service stairs and platforms. Deviations should occur only after careful consideration, extensive testing,
35、 risk assessment and thorough service evaluation have shown alternative methods or conditions to be satisfactory. Such deviations are outside the scope of this standard and a manufacturer should be able to demonstrate an equivalent level of protection. This document is a type-C standard as stated in
36、 EN ISO 12100. This document is of relevance, in particular, for the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium and large enterprises); health and safety bodies (regulators, accident prevention organizations, mar
37、ket surveillance etc.) Others can be affected by the level of machinery safety achieved with the means of the document by the above-mentioned stakeholder groups: machine users/employers (small, medium and large enterprises); machine users/employees (e.g. trade unions, organizations for people with s
38、pecial needs); service providers, e.g. for maintenance (small, medium and large enterprises); consumers (in case of machinery intended for use by consumers). The above-mentioned stakeholder groups have been given the possibility to participate at the drafting process of this document. The machinery
39、concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are stated in type-A or type-B standards, the requirements of this type-C standard tak
40、e precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. Deviations from requirements do not fall within the presumption of conformity given by the standard. BS EN 123128:2018EN 12312-8:2018 (E) 6
41、1 Scope 1.1 General This document specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, the operation and the maintenance of maintenance or service stairs and platforms when used as intended, including misuse reasonably foreseeable
42、by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It also takes into account some requirements recognized as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines a
43、nd handling agencies. These machines are designed to be used as aircraft ground support equipment with the intended use to serve aircraft in outdoor conditions on the apron. They can also be used indoors at hangars. The use of such equipment for operations not in conjunction with aircraft is not def
44、ined as intended use therein. Due to the good operational conditions on the apron, deviations from some clauses of EN 280 were deemed acceptable. This European Standard applies to: a) self-propelled fixed or adjustable maintenance or service stairs and elevating platforms; b) towable maintenance or
45、service stairs and platforms equipped with powered means, e.g. for height adjustment, stabilizers; designed for aircraft maintenance or service purposes including access to the aircraft. NOTE 1 Powered will be also understood as manual effort stored in springs or hydraulic accumulators, etc., the da
46、ngerous 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 standard that can apply can also be used as a guideline for the design of towable maintenance or service stairs and
47、 platforms without powered means. This European Standard does not apply to: c) maintenance docks either fixed to the ground or moveable only for docking procedure; d) ground support equipment specifically intended, built and equipped with a fluid system for aircraft de-icing and anti-icing (see EN 1
48、2312-6); NOTE 3 This does not prevent aircraft de-icers meeting the requirements of EN 12312-6 from being used as a means of access for aircraft maintenance, e.g. windshield cleaning, etc. e) mobile elevating work platforms (MEWP) used at the airports for purposes other than aircraft maintenance, e.
49、g. buildings and facilities (see EN 280). No extra requirements on noise and vibration are provided other than those given in EN 1915-3 and EN 1915-4. NOTE 4 EN 1915-3 and EN 1915-4 provide the general GSE vibration and noise requirements. 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 or service stairs and platforms which are manufactured before the date of publica
