AMS 1428 Fluid, Aircraft De-icing and Anti-icing, Non-Newtonian (Pseudoplastic) Fluid - SAE Types II, III and IV

Developed by the Society of Automotive Engineers (SAE), the AMS 1428 standard describes the requirements for three types of de-icing and anti-icing materials that are in the form of a non-Newtonian liquid.

To remove snow, ice, frost, and other frozen precipitation from aircraft surfaces, SAE AMS1428 Type II, III, and IV de-icing fluids containing propylene glycol and possessing anti-ice properties are used. These de-icing fluids are produced in a light yellow color to avoid confusion with Type 1. The use of propylene glycol is intended to increase the freezing point of the fluid. Special gelling agents are added to the formula during production, increasing its viscosity upon contact with cold. This, in turn, improves its adhesion to the applied surface.

Commercial aircraft companies have essentially been using de-icing and anti-icing fluids for many years to prepare aircraft for safe takeoff and flight in winter. Newer, more effective de-icing and anti-icing fluids are now increasingly preferred for their ability to remove ice or snow contaminants more quickly and effectively, and industry standards are being updated to reflect these latest developments.

De-icing and anti-icing fluids are developed by the Society of Automotive Engineers (SAE) according to industry standards. In addition, the International Standards Organization (ISO) publishes similar standards. The SAE AMS 1424 and SAE AMS 1428 standards are specifications that contain performance requirements for de-icing and anti-icing fluids. The AMS 1424 standard applies to SAE Type I fluids and the AMS 1428 standard applies to SAE Type II, III and IV fluids.

These standards contain specifications for a fluid aerodynamic acceptance test jointly established by the American Aerospace Industries Association and the European Aerospace Industries Association.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides 1428 fluid, aircraft defrosting and anti-icing liquid testing services within the scope of AMS 1428 standard, with its trained and expert staff and advanced technological equipment.
