ISO 11075 Aircraft - Anti-Icing Anti-Icing Fluids - ISO Type I

The ISO 11075 standard, developed by the International Organization for Standardization (ISO), defines requirements for ISO type I fluids used in the removal and prevention of ice, snow or frost on the outer surfaces of the mainline and on the ground regional civil transport aircraft.

ISO 11075 Aircraft - Anti-Icing Anti-Icing Fluids - ISO Type I

ISO 11075 is applicable to de-icing/anti-icing fluids commonly used in aircraft. However, applicability may have limitations for certain aircraft types. It is the airplane operator's responsibility to consult the airplane operations manual, aircraft maintenance manual, and airplane manufacturer's service letters to identify limitations/restrictions on the use of de-icing/anti-icing fluids conforming to ISO 11075.

Frost, ice, or snow deposits that could seriously affect an aircraft's aerodynamic performance and/or controllability are effectively removed by following the procedures outlined in this document. Various local rules regarding aircraft cold weather operations are very specific and must be strictly adhered to.

Frost, snow, slush on any propeller, windshield, or power plant installation or airspeed, altimeter, rate of climb, or flight altitude indicator systems
or ice; Any freezing of snow, slush or ice on the wings or stabilizers or control surfaces, in the spaces between the fuselage and the control surfaces, or in the spaces between the control surfaces and the control lugs, or on the upper surfaces of the wings or stabilizers or control surfaces, can be extremely dangerous in flight. Therefore, aircraft surfaces will be checked for contamination prior to take-off.

De-icing/anti-icing procedures should only be performed by trained and qualified personnel. Companies providing de-icing/anti-icing services must maintain an acceptable level of proficiency.
must have both a Qualification Program and a Quality Assurance Program to monitor and maintain.

Application equipment should be thoroughly cleaned before first being filled with de-icing/anti-icing liquid to avoid liquid contamination. De-icing/anti-icing fluid from trucks must not be heated in confined or poorly ventilated areas. The integrity of the fluid in the spray nozzle should be checked periodically.

These procedures specify recommended methods for de-icing and de-icing aircraft on the ground to maintain an aerodynamically clean aircraft. When aircraft surfaces are contaminated, they will be thawed prior to shipping. Where there is a risk of contamination of aircraft surfaces during shipment, these surfaces shall be anti-icing. If both defrosting and anti-icing are required, the procedure can be performed in one or two steps. The choice of a one- or two-stage process, air
conditions, equipment available, fluids available and holding time to be reached.

Among the services provided by our organization within the framework of material testing services, there are also ISO 11075 standard tests.
