scope:

NEN-EN 12312-4 specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of passenger boarding bridges (PBBs) 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 handling agencies. This European Standard applies to: a) apron-drive bridges; b) fixed-head bridges (also referred to as nose-loaders) or pedestal bridges; c) suspended bridges, for embarking/disembarking of passengers. It is applicable from the interface with the terminal building, which can be movable, e.g. on two levels to separate arrival and departure level to the connection with the aircraft including fixed tunnels. This European Standard does not apply to: d) elevating lounges; e) passenger stairs; f) other form of aircraft access equipment; g) automatic PBB positioning. This European Standard does not establish requirements for hazards caused by noise and vibration. This part of EN 12312 is not applicable to PBBs which were manufactured before the date of publication of this standard by CEN. This part of EN 12312 when used in conjunction with EN 1915-1, EN 1915-2 and EN 1915-4 provides the requirements for PBBs.
