The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide the sample selection and endurance time test procedures, for SAE Type II, III, and IV aircraft deicing/anti-icing fluids, required for the generation of endurance time data of acceptable quality for review by the SAE G 12 Holdover Time Subcommittee.
This document has been updated to reflect current practices for conducting endurance time tests with SAE Type II, III, and IV fluids. Notably, a requirement has been added to conduct tests with Type III fluids intended for use applied heated and test conditions have been updated to reflect changes made to the conditions encompassed by the holdover time guidelines (e.g., addition of light and very light snow). In addition, a test protocol has been added for conducting endurance time tests in natural frost. Finally, editorial changes have been made to improve clarity.
