DIN EN 12312-1:2024-09

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 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 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 and ground handling agencies. This European Standard applies to: a) self-propelled stairs with a driver's seat; b) towable passenger stairs; c) towable stairs with power-operated devices, for example for height adjustment, supports; d) automatic levelling systems of stairs for embarking/disembarking of passengers. "Powered" is also understood as manual effort stored in springs or hydraulic accumulators, etcetera, 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 document that can apply can 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) aircraft upper deck door access. This part of EN 12312 does not apply to passenger stairs manufactured before the publication of this standard by CEN. This part of EN 12312, when used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3:2009 and EN 1915-4, provides the requirements for passenger stairs. This document has been prepared by Technical Committee CEN/TC 274 "Aircraft ground support equipment", the secretariat of which is held by DIN (Germany). The responsible German standardization committee is Working Committee NA 131-08-01 AA "Luftfracht und Bodengeräte" ("Air freight and Ground equipment " at DIN Standards Committee Aerospace (NL).
