This European Standard specifies the technical requirements to minimise the hazards listed in clause 4 which can arise during the commissioning, operation and maintenance of deicers and equipment designed exclusively for deicing and washing of aircraft with deicing/antiicing/washing liquids when carried out in 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 GSE manufacturers as well as airlines and handling agencies. NOTE Safety of aircraft in connection with deicing/antiicing operations is not dealt with in this European Standard. Any, even minor, aircraft deicing or antiicing operation directly affects flight safety on take-off. Prevention of aeronautical accidents resulting from in-flight icing principally concerns the fluids and methods used, but it may in certain cases also concern deicing or antiicing equipment design or operation. These aeronautical aspects are not covered in this European Standard (see also Joint Aviation authorities (JAA), Joint Aviation Regulations (JAR) JAR-OPS subpart D 45 and any associated material). This standard applies to: self-propelled deicers with fixed platform or hinged boom; towable deicers with fixed platform or hinged boom; stationary deicing/antiicing equipment (e. g. fixed boom, gantry or tower cranes equipped with aircraft deicing/antiicing fluid systems). This standard does not apply to: fixed installations, such as separate storage tanks or heating and filling stations, which are not an integrated part of the stationary deicing equipment; hydraulic control systems; pneumatic systems; flow generating systems as such. This standard does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3. This standard is not dealing with hazards in respect to a standard automotive chassis and the traffic on the apron. This part of EN 12312 is not applicable to deicers and deicing/antiicing equipment which are manufactured before the date of publication by CEN of this standard. This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.
