EN 12312-6:2004 (E)
Introduction
This European Standard specifies health and safety requirements, as well as some functional and performance
requirements, for deicers and equipment intended for deicing/antiicing of all aircraft types commonly in service in
civil air transport. It contains functional and environmental aspects of deicing in the informative annexes B, C
and D.
The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical,
and usable deicers and deicing/antiicing equipment. Deviation from the recommended criteria should occur only after
careful consideration, extensive testing, risk 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 1070:1998.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-
cated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-
visions 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 of this type C standard.

EN 12312-6:2004 (E)

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 prEN 1915-4 and prEN 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.

4 List of significant hazards
The list of hazards (see annex A) 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 deicers and
deicing equipment and which require action to eliminate or reduce risks.
5 Safety requirements and/or measures
5.1 General requirements
5.1.1 Deicers and deicing/antiicing equipment shall conform to the relevant requirements of EN 1915-1:2001
unless otherwise specified in this standard. 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 11076:2000.
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.
5.3 Stability and strength
5.3.1 Calculation of stability and strength shall be carried out according to EN 1915-2:2001. Deicing equipment
shall be stable under all working conditions.
Any life limited components shall be calculated for a foreseeable lifetime of 10 000 hours of operating taking into
account foreseeable wear and corrosion.
5.3.2 Deviating from 5.2.2.3 of EN 1915-2:2001 the maximum number of persons in the cabin/basket shall be
two. The maximum rated load shall be 205 kg.
5.3.3 Where intended operation includes deicing/antiicing with aircraft engines running, the additional forces
shall be taken into account.
5.3.4 Spraying forces are considered as being dynamic forces (see 5.2.2.4 of EN 1915-2:2001).
5.3.5 Special attention shall be given to the calculation of telescopic boom joints.
8

---------------------- Page: 9 ----------------------

EN 12312-6:2004 (E)
5.3.6 The design of deicers shall not need stabilizers to ensure stability.
Where chassis spring locks or torsion bars are used, they shall automatically be engaged when the cabin/basket is
moved out of the base position.
5.3.7 Where open baskets are used, the nozzle and hose(s) shall be considered as structural parts for calcula-
tion purposes.
5.3.8 For fatigue stress analysis, the factor for the intended load spectrum shall not be less than one and the
4
amount of load cycles never less than 2 × 10 (see also 5.2.6 of EN 1915-2:2001).
5.3.9 The maximum overturning and corresponding stabilizing moments shall be calculated about the most unfa-
vourable tipping lines and with empty tanks.
Tipping lines shall be determined as shown in ISO 4305:1985.
NOTE For solid and foam-filled tyres the tipping lines may be taken at 1/4 of the tyre ground contact width from the outside
of the ground contact width.
5.3.10 In addition to the verification of stability and strength in accordance with EN 1915-2:2001 the following tests
shall be done:
 vehicle driving over a test fixture at maximum allowable speed (6 km/h) in forward and reverse directions. The
wheels driving over test fixture shall be the ones giving highest stresses in boom structure. The test fixture
shall be a device used to simulate obstacles that may be encountered on an airport ramp (e.g. wheel chocks,
storm drains, fuel pit lids, snow and ice ruts, etc.). The test fixture shall be made out of wood or any other simi-
lar material measuring 100 mm (4 in) high, 150 mm (6 in) wide and 600 mm (24 in) long. The top corners shall
be symmetrically cut at 45° angles along the longitudinal length of the member providing a top flat surface
measuring 50 mm (2 in) in width. The test fixture shall be secured in such a manner that prevents sliding or
overturning as the vehicle is driven over it during dynamic load testing.
 vehicle driving at maximum allowable speed (6 km/h) in forward and reverse directions and suddenly applying
brakes to simulate emergency (panic) stops.
Both tests shall incorporate boom orientation and fluid tank level which generate maximum stress on the structural
boom components. The basket/enclosed cabin shall be loaded at maximum rated capacity. In addition to these
loads the windload shall be incorporated by calculation afterwards. During the tests the stress levels shall be
measured using strain gauge or equivalent measurement techniques. How and where to mount the strain gauges
shall be done in accordance with relevant industry practices.
NOTE Relevant recommendations for the mounting of strain gauges can be found e.g. in IIW (International Institute of
weldings) publications (see Bibliography).
The design verification shall be done comparing measured stresses (with incorporated wind loads) and yield
strength of the material in question. To pass the tests the minimum acceptable safety factors are as stated in
Table 1 in EN 1915-2:2001.
5.4 Safeguards and safety devices
5.4.1 Operator's seats shall be provided with 3 point type inertial reel seat belts as used on standard automotive
vehicles.
5.4.2 Harness anchorage points for each person in accordance with EN 795:1996 Class A shall be provided at
baskets.
5.5 Emergency systems
5.5.1 Deicers shall be fitted with:
9

EN 12312-6:2004 (E)
 an emergency lowering control at ground level or at an accessible position (see 5.13 of EN 1915-1:2001 for
access). The design and position of this control shall ensure visibility on the movement of the cabin/basket.
This control device shall override the control devices for lifting and lowering;
 an emergency control system in the cabin/basket to move the boom in case of primary power loss;
 an emergency valve at the base lifting cylinder. Provision shall be made for safe access, e.g. portable ladder,
and for use of personal protective equipment against falling.
5.5.2 Emergency stops shall meet the requirements of EN 418 category 0 (see 4.1.5 of EN 418:1992). At least
one shall be provided in the cabin/basket on deicers. 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:
