BS EN 12312-18:2005+A1:2009EN 12312-18:2005+A1:2009 (E) 4 Introduction This document specifies health and safety requirements, as well as some functional and performance requirements for nitrogen or oxygen units intended to be used for all aircraft types commonly in s
25、ervice in civil air transport. The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical and practical nitrogen or oxygen units. Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk
26、assessment and thorough service evaluation have shown alternative methods or conditions to be satisfactory. This document is a Type C standard as stated in !EN ISO 12100“. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope
27、of this document. When provisions of this Type C standard are different from those which are stated in Type A or B standards, the provisions of this Type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions
28、of this Type C standard. BS EN 12312-18:2005+A1:2009EN 12312-18:2005+A1:2009 (E) 5 1 Scope This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of nitrogen or oxygen units when carried out in
29、 accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE), manufacturers as well as airlines and handling agencies. This
30、document applies to: all types of mobile nitrogen units and oxygen units with transportable gas cylinders interchangeable for filling purposes; equipment to be carried with other GSE or vehicles, e.g. skid mounted units, intended for the manual refill of gaseous nitrogen or oxygen on aircraft (Examp
31、les see Annex A). NOTE Generally oxygen units are used under aircraft maintenance conditions, not under commercial servicing conditions. This document does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3. This document do
32、es 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 nitrogen or oxygen units which are manufactured before the date of publication of this document by CEN. !This part of EN 12312 is intended to be used
33、in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.“ 2 Normative references The following referenced documents are indispensable for the application of this document.
