23、02+A1:2009 (E) 4 Introduction This European Standard specifies health and safety requirements, as well as some functional and performance requirements for potable water service equipment intended for servicing all aircraft types commonly in service in civil air transport. The minimum essential crite
24、ria are considered to be of primary importance in providing safe, serviceable, economical, and practical potable water service equipment. Deviations from the recommended criteria should occur only after careful consideration, extensive testing, risk assessment and thorough service evaluation have sh
25、own alternative methods or conditions to be satisfactory. This European Standard is a Type C standard as stated in !EN ISO 12100“. 1 Scope This European Standard specifies the technical requirements to minimise the hazards listed in clause 4 which can arise during the commissioning, operation and ma
26、intenance of potable water service equipment 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) manufacture
27、rs as well as airlines and handling agencies. This standard applies to: self-propelled potable water vehicles; towable potable water vehicles; moveable parts of ramp integrated systems, designed for servicing aircraft and intended to be used under the conditions given in clause 1 of EN 1915-1:2001 (
28、Examples see annex A). This standard does not establish requirements for hazards caused by noise and vibration. This Part of EN 12312 is not applicable to potable water service equipment which is manufactured before the date of publication of this standard by CEN. !This part of EN 12312 is intended
29、to be used 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.

35、apply. 3.1 potable water service equipment ground support equipment (GSE) for servicing aircraft with potable water by means of a pump 3.2 potable water vehicle self-propelled or towable potable water service equipment 3.3 open work material flooring material for standing areas with openings to allo
36、w self-draining and cleaning 4 List of hazards The list of risks and hazards (see annex B) is based on EN 1050:1996 and contains the hazards and hazardous situations, as far as they are dealt with in this European Standard, identified by risk assessment as significant for potable water service equip
37、ment and which require action to eliminate or reduce risks. Not covered are risks and hazards due to a standard automotive chassis, the traffic, !repair“ and general misuse. 5 Safety requirements and/or measures 5.1 General requirements 5.1.1 !Potable water service equipment shall conform to the rel
38、evant requirements of EN 1915-1, EN 1915-2, EN 1915-3 and EN 1915-4 unless otherwise specified in this standard.“ They shall also conform to the specific requirements of this standard. 5.1.2 Stability and strength calculations shall be carried out in accordance with !EN 1915-2“.

39、A1:2009 EN 12312-12:2002+A1:2009 (E) 6 5.1.3 The connection to the aircraft system shall meet the requirements of !ISO 17775“. 5.1.4 Where the potable water service equipment is intended to be moved on public roadways, the dimensions, laden mass and other characteristics shall meet all applicable go
40、vernmental regulations. NOTE Applicable governmental regulations are dependent on the airport of use. 5.1.5 The ground clearance shall allow without interference the transversing of two surfaces intersecting at an angle of 3 (5 %) either in bridging or cresting. 5.1.6 The height of the potable water
41、 vehicle shall allow the servicing of aircraft as intended by the manufacturer. NOTE Parts of potable water vehicles intended to be driven underneath the aircraft should not be more than 1,60 m (63 in) above the ground (see clause 0 of EN 1915-1:2001 negotiation). This might cause problems in fulfil
42、ling the requirements in ISO 3411:1995. 5.1.7 All parts of the water system shall be made of materials acceptable for use in connection with potable water. Where stainless steel is used, the material shall be acid resistant like quality No 1.4404 according to !EN 10088-1“. All inside surfaces shall
