Fluid, Aircraft Deicing/Anti-Icing, Non-Newtonian (Pseudoplastic), SAE Types II, III, and IV
AMS1428L
This foundation specification (AMS1428L) and its associated category specifications (AMS1428/1 and AMS1428/2) cover three types of deicing/anti-icing fluids, each in the form of a non-Newtonian fluid.
Rationale:
Sections 4.2.2 and 4.2.3 have been renumbered and revised to align with the changes made in AMS1424 to the expiration date for both initial qualification and periodic requalification. Section 3.2.3.2 was updated to replace the ASTM D2196 method for determining viscosity with AS9968 which was recently revised, references to MSDSs have been replaced with SDS, along with other editorial changes associated with renumbering and relocating 4.2.2, 4.2.3, and 4.5.1.4. Wording was added to identify the middle speed ramp as an option for aerodynamic acceptance testing, and to clarify the viscosity required for previously qualified fluids wishing to test for the mid-speed ramp. Section 3.2.5.4 was revised per the aerodynamic working group’s recommendation to change the fluid elimination criteria from a percentage to a final fluid thickness.
