Water Spray and High Humidity Endurance Test Methods for SAE AMS1424 and SAE AMS1428 Aircraft Deicing/Anti-icing Fluids
This document establishes the minimum requirements for an environmental test chamber, and test procedures to carry out anti-icing performance tests according to the current materials specification for aircraft deicing/anti-icing fluids. The primary purpose for such a test method is to determine the anti icing endurance under controlled laboratory conditions of AMS1424 Type I and AMS1428 Type II, III, and IV fluids.
This document brings clarifications to test methods and proposes some editorial changes. The main change is in 5.4 where the icing intensity measurement procedure has been reviewed and updated; the indirect method has been removed as an approved method. In 4.2.2 and 220.127.116.11, the relative humidity percentage (% RH) requirement has been changed to reflect the minimum %RH requirement of the HHET in 3.3. Section 18.104.22.168 has also been modified to reflect the actual test conditions.
