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 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 1.345 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."

They shall also conform to the specific requirements of this standard. 5.1.2 The operating conditions shall be given by the manufacturer. Deicers shall be designed to operate safely in a continuous relative humidity of 94 %. Materials and devices used shall take into account the environmental conditions intended to be encountered by deicing equipment, e.g. with respect to temperature, sun, precipitation and freezing effects. NOTE The operating conditions and the materials chosen are depending on the airport of use (see clause 0 of EN 1915-1:2001 — negotiation). 5.1.3 The design of deicers and deicing/antiicing equipment shall take into account the operational conditions for deicing/antiicing as given in !ISO 11076". 5.2 Spray system 5.2.1 The control of hand held spray guns shall be of the hold-to-run type. 5.2.2 Fixed spray guns of deicers shall be prevented from spraying directly towards the operator's position, e.g. by means of a positive fit. 5.2.3 In case of spray gun failure it shall be possible to stop the fluid flow by means of an additional shut-off valve.

Additional emergency stops shall be installed on the outer contour reachable from ground level, e.g. on each longitudinal side. 5.5.3 Emergency stops on deicers shall:  stop and hold all boom and cabin/basket movements;  shut down the fluid pump and heater;  apply parking brakes. Emergency stops on deicers shall not:  impede the emergency lowering function;  stop the function of communication systems;  switch off working lights;  shut down fire extinguisher systems, where applicable. 5.5.4 Emergency stops on stationary systems shall be installed at operator's position(s) as well as on the structure and reachable from ground level, e.g. on each travelling gear or fundament. 5.5.5 On stationary deicing/antiicing equipment emergency stops shall stop all motions, the fluid supply and the spraying system. 5.5.6 To prevent overheating and overpressure, the fluid heater shall be equipped with safety devices. As a minimum, two independent overheat thermo-switches and two relief valves able to conduct the amount of fluid or steam generated by the heater shall be installed. 5.5.7 The deicing/antiicing equipment shall be furthermore provided with devices to shut down automatically fluid pumping and heating systems when a hazardous condition, e.g. overheating, overpressure, arises while these sys-tems are operating. These devices, when actuated, shall allow a deicer to be driven away from the aircraft. SIST EN 12312-6:2004+A1:2009

In addition, each harness anchorage point shall be tested according to EN 795 Class A1. If the boom construction cannot withstand the stresses occurring when carrying out the static test, the basket may be supported while the an-chorage point is tested.

Fluid system B.1 General This annex describes recommendations for performance and capacity of fluid systems for deicing equipment as well as methods for verification of fluid systems, important for the reliability of the deicing operation. It is not the intention of this annex to specify a comprehensive set of technical design criteria for deicing equipment for aircraft, but only those relating to function, safety and performance. The annex is divided into the following three subdivisions:  B.2 Functional information;  B.3 Recommendations for fluid system performance and capacity;  B.4 Verification of fluid system functions. The general functional requirements of a deicer can be found in ISO 11077:1993. The content of B.2, B.3 and B.4 is agreed as internationally mandatory by industry, civil aviation authorities and airlines. These requirements have been developed over a number of years and they play an important role in designing deicing/antiicing equipment. B.2 Functional information B.2.1 General To optimize the snow and ice removal effect, the fluid system of the deicing equipment should be designed for spray-ing fluid up to a temperature of 85 °C (the maximum allowed temperature of the surface of the aircraft is 80 °C). B.2.2 Size/design of deicing equipment The size and design of the deicing equipment should be agreed upon between manufacturer and user, as the opera-tional conditions can vary considerably from one airport to another. The requirements can be very different concerning reach of aerial device, tank capacity, means of heating, etc. Where a deicer is to be used for other purposes than deicing (e.g. maintenance work, aircraft washing, etc.), open basket deicers are often preferred; but in airports where the operators are deicing for longer periods or are deicing aircraft with running engines, a deicer with enclosed cabin offers a much better working environment concerning exposure to noise, weather, glycol, aerosols, etc. As training of the operator is of major importance in order to perform a fast, technically and environmentally safe deicing operation, it is important that the basket/operator's cabin has the capability to carry a second person. Certain conditions in the different airports (e.g. narrow gates, low tunnels, passenger boarding bridges, etc.) can give rise to special requirements for the maximum width and height of the deicer with the aerial device in base position. This has to be stipulated between the manufacturer and the user. SIST EN 12312-6:2004+A1:2009
