The foundation specification (AMS1428) and the category specifications (AMS1428/1 and AMS1428/2) cover deicing/anti-icing materials in the form of a fluid.

This foundation specification (AMS1424S) and its associated category specifications (AMS1424/1 and AMS1424/2) cover a deicing/anti-icing material in the form of a fluid.

This document describes a standard method for measuring the viscosity of thickened (AMS1428) Type II/III/IV Aircraft Deicing/Anti-icing Fluids. The determination of viscosity for a Non-Newtonian fluid is very sensitive to shear and differences in sample chamber geometry. Even slight differences can have a large effect on measurement results. The test parameters and associated error for this standard are applicable to the Brookfield LV viscometer. A Brookfield LV or equivalent viscometer shall be used. To be considered equivalent, an alternate viscometer must demonstrate statistically equivalent performance, i.e., accuracy and precision when testing thickened (AMS1428) fluids using the same test parameters and conditions.Test parameters and conditions outside of the ranges described within this standard may be used only if they meet minimum limits for precision and accuracy established for the Brookfield LV viscometer.

This foundation specification (AMS1424R) and its associated category specifications (AMS1424/1 and AMS1424/2) cover a deicing/anti-icing material in the form of a fluid.

This SAE Aerospace Recommended Practice (ARP) covers requirements for in-truck manufacturing of SAE AMS1424 Type I deicing/anti-icing fluid, and contains technical and other requirements which apply to the in-truck manufacturing of Type I deicing/anti-icing fluid

The foundation specification (AMS1428J) and the category specifications (AMS1428/1 and AMS1428/2) cover deicing/anti-icing materials in the form of a fluid.

The foundation specification (AMS1428J) and the category specifications (AMS1428/1 and AMS1428/2) cover deicing/anti-icing materials in the form of a fluid.

This SAE Aerospace Information Report (AIR) provides a description of a screening method for use in the field for verifying an AMS 1428 anti-icing fluid is above its minimum low shear viscosity as published with holdover time guidelines. The test will determine if the fluid is (a) satisfactory, (b) unsatisfactory, or (c) borderline needing more advanced viscometry testing. Other field tests may be required to determine if an anti-icing fluid is useable, such as refractive index, appearance or other tests as may be recommended by the fluid manufacturer.

This AS describes a standard method for viscosity measurements of thickened (AMS1428) anti-icing fluids. Fluid manufacturers may publish alternate methods for their fluids. In case of conflicting results between the two methods, the manufacturer method takes precedence. To compare viscosities, exactly the same measurement elements (including spindle and container size) must have been used to obtain those viscosities.
