Overview
ISO 11075:2007 - Aircraft - De-icing/anti-icing fluids - ISO type I defines the international requirements for ISO type I de-icing and anti-icing fluids used on the ground to remove and prevent ice, snow or frost from exterior surfaces of main line and regional civil transport airplanes. The standard harmonizes critical fluid characteristics (Newtonian or non-Newtonian) to ensure safe ground de-icing/anti-icing operations worldwide and endorses industry practice by aligning with SAE AMS 1424.
Key topics and requirements
- Scope and applicability: Applies to de-icing/anti-icing fluids for main line airplanes (maximum ramp mass > 50 000 kg) and regional airplanes (10 000–50 000 kg). Applicability may be limited for particular aircraft types - operators must consult the aircraft operations manual, maintenance manual and manufacturer service letters for restrictions.
- Designation: Fluids must be designated and used as ISO type I for international operations (see ISO 11076 for application guidance).
- Conformance to AMS 1424: ISO 11075:2007 requires fluids to conform to Aerospace Material Specification AMS 1424, with AMS 1424 maintained by SAE Committee G‑12 with AEA and ISO experts to reflect state-of-the-art formulations and testing.
- Application and control methods: Methods for applying and controlling ISO type I fluids shall follow ISO 11076, ICAO Doc. 9640‑AN/940 and relevant civil aviation authority requirements.
- Safety and standardization objective: The standard’s aim is to standardize critical properties of de-icing/anti-icing fluids to improve safety and interoperability in ground de-icing operations.
Applications and users
ISO 11075:2007 is directly useful to:
- Aircraft operators and airlines managing ground de-icing/anti-icing programs
- Airport ground handling and de-icing service providers
- De-icing/anti-icing fluid manufacturers and suppliers seeking ISO type I certification
- Aircraft maintenance engineers and safety managers verifying compatibility and limitations
- Civil aviation authorities and regulators harmonizing operational guidance
Practical uses include selecting compliant ISO type I fluids, developing ground de-icing procedures, training groundcrew, and ensuring regulatory and manufacturer compatibility before treating aircraft surfaces.
