The purpose of this 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 Committee. The related standard ARP5718 provides the process by which endurance time data is converted to holdover times for publication by regulators and subsequent use by aircraft operators.
