This document specifies the laboratory test methods and test requirements for the testing of aerodynamic, thermal, acoustic and the electrical performance characteristics of non-ducted mechanical supply and exhaust residential ventilation units used in single dwellings.The purpose of this document is not to consider the quality of ventilation but to test the performance of the equipment.In general, a ventilation unit contains:- fans for mechanical supply and exhaust;- air filters;- air-to-air heat exchanger for heat and possibly humidity recovery;- control system;- inlet and outlet grilles.Such equipment can be provided in more than one assembly, the separate assemblies of which are designed to be used together.Such equipment can contain alternating heat exchangers which provide separate supply and exhaust air flows.In certain cases, i.e. alternating ventilation unit, it may be declared that the equipment can be installed in such a way that it serves more than one room. For the purpose of this document, these products are assessed in a single room.This document does not deal with ducted units which are covered by prEN 13141-7 or units with heat pumps.Safety requirements are given in EN 60335-2-40 and EN 60335-2-80.

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 stairsfor 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.

This document applies to GSE when used in civil air transport as intended by the manufacturer and contains safety requirements relating to the equipment in general.This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of GSE when used as intended including any reasonably foreseeable misuse 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 part of EN 1915 is intended to be used in conjunction with EN 1915-2:2001+A1:2009, EN 1915-3:2004+A1:2009 (for self-propelled GSE) and EN 1915-4:2004+A1:2009, and with the relevant part of EN 12312 to give the requirements for the types of GSE within the scope of EN 12312.When EN 12312 does not contain a relevant part for a GSE, EN 1915 (all parts) gives general requirements that may apply, although additional machine specific requirements, to be determined by the manufacturer, are likely to be required.This part of EN 1915 does not apply to automotive parts approved for public vehicles in the EU and EFTA, when used on GSE for the purpose for which they are designed.This part of EN 1915 does not establish additional requirements for the following:a) operation elsewhere than in an airport environment;b) operation in severe conditions, e.g. ambient temperature below -20 °C or over 50 °C, tropical or saturated salty atmospheric environment, strong magnetic or radiation field;c) operation subject to special rules, e.g. potentially explosive atmosphere except as regards operation in the vicinity of an aircraft fuel tank during fuelling operation;d) hazards caused by power supply other than from electrical networks;e) hazards occurring during construction, transportation, decommissioning and disassembly of the GSE;f) hazards caused by wind velocity in excess of the figures given in this document;g) direct contact with food stuffs;h) earthquake, flood, landslide, lightning and more generally any exceptional natural event;i) electromagnetic compatibility (EMC);j) hazards caused by noise and vibration, see EN 1915-3:2004+A1:2009 and EN 1915-4:2004+A1:2009.While this standard gives some basic requirements for wireless remote controls, additional requirements will be necessary.This part of EN 1915 is not applicable to GSE which are manufactured before the date of publication by CEN of this document.
