Description / Abstract:

This International Standard specifies the general functional, performance and safety requirements for a self-propelled vehicle equipped with a boom type aerial device and aircraft de-icing / anti-icing fluid (ADF) spraying systems, hereinafter designated as "de-icer".

De-icers are intended to spray aircraft under freezing conditions with appropriate fluids:

a) ISO type I de-icing / anti-icing fluid (see ISO 11075), or

b) ISO type II, III or IV de-icing / anti-icing fluid (see ISO 11078),

mixed with water (if applicable) and heated as necessary, in order to enable operators to de-ice / anti-ice aircraft in accordance with the detailed methods stated in ISO 11076.

De-icers can also be used, without spraying, as a means of technical staff access to elevated parts of aircraft, e.g. for maintenance. Reduced performance requirements can apply in such a case where identified in the present International Standard, but personnel safety requirements remain applicable.

The requirements of this International Standard were determined based on generally recognized assumptions as to:

a) the normally intended use of aircraft ground support equipment on the ramp of international civil airports in order to handle, service or maintain civil transport aircraft ;

b) the environmental (surface, slope, weather, lighting, operating rules, staff qualification, etc.) conditions prevailing on the ramp area of the majority of international civil airports. In addition to customary environment conditions in this context, it is to be assumed that de-icers will be operated on snowy, icy, muddy or slushed ramp surfaces and under freezing precipitation conditions.

It is assumed the manufacturers of de-icers define in the relevant documentation the specifically intended conditions of use and environment for their equipment, and the purchasers systematically review their own specific conditions of use and environment in order to determine whether those stated are adequate, or negotiate with the manufacturer appropriate modifications to ensure they are.

NOTE 1 Negotiation between manufacturer and purchaser / user is considered essential to establish or verify the adequate conditions of use and design parameters.

This International Standard does not specify a comprehensive set of technical design criteria for aircraft de-icing / anti-icing vehicles, but only those relating to the main functional, safety and performance requirements.

This International Standard is not applicable to stationary equipment, e.g. gantries, cranes, used to perform de-icing / anti-icing operations on aircraft.
