本欧洲标准规定了技术要求，以最大限度地减少在按照预期使用时乘客楼梯的调试，运行和维护期间可能出现的第4条所列的危险，包括制造商合理预见的滥用，按照规格由制造商或其授权代表给出。它还考虑到当局，飞机和地面支持设备（GSE）制造商以及航空公司和处理机构认可的一些要求。 本欧洲标准适用于: a）带有司机的自走式楼梯; b）行人控制楼梯; c）装有动力装置的可拖动楼梯，例如用于高度调节，稳定器; d）楼梯自动调平系统 乘客上下班。 动力还应被理解为存储在弹簧或液压蓄能器等中的手动操作，其可以在手动停止或直接施加用于提升或降低负载的手动努力之后产生或可以继续的危险动作。 可以适用的本标准的这些条款也可用作设计无动力装置的可拖动楼梯的指南。 这个欧洲标准没有

This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, the operation and the maintenance of passenger stairs when used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies. This European Standard applies to: a) self-propelled stairs with seated driver; b) pedestrian controlled stairs; c) towable stairs equipped with powered means, e.g. for height adjustment, stabilisers; d) automatic levelling systems of stairs for embarking/disembarking of passengers. Powered should also be understood as manual effort stored in springs or hydraulic accumulators, etc., the dangerous 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. Those clauses of this standard that can apply may also be used as a guideline for the design of towable stairs without powered means. This European Standard does not establish additional requirements for the following: 1) persons falling out of an aircraft with the passenger stairs not in position; 2) hazards resulting from a moving stairway (escalator); 3) upper deck door access. This part of EN 12312 is not applicable to passenger stairs which are manufactured before the date of publication by CEN of this standard. This part of EN 12312 when used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 and EN 1915-4 provides the requirements for passenger stairs.
