AMS1428K Fluid, Aircraft Deicing/Anti-Icing, Non-Newtonian (Pseudoplastic), SAE Types II, III, and IV

This document has been revised to update references to ARP4737 (discontinued) with AS6285. The precautionary note from 3.1.5 has been removed, as all fluids are now required to be colored. Sections 4.2.2 and 4.5.1.2 were updated to clarify periodic testing requirements per the requalification working group recommendations. The labeling and purchase document specifications in 5.1.2 and 9.4 were also revised so that they more accurately reflect the additions of AMS1428/1 and AMS1428/2.
