Endurance Time Tests for Aircraft Deicing/Anti-icing Fluids SAE Type I
The purpose of this ARP is to provide the sample selection criteria and test procedures for SAE Type I 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. A significant body of previous research and testing has indicated that all Type I fluids formulated with glycol perform in a similar manner from an endurance time perspective. This applies to Type I deicing/anti-icing fluids formulated with propylene glycol, ethylene glycol, and diethylene glycol only. Type I deicing/anti-icing fluids containing these glycol bases no longer require testing for endurance times. The methods described in this ARP shall be employed, however, if endurance time testing of a glycol-based Type I deicing/anti-icing fluid is desired or requested by a fluid manufacturer, operator or other organization. Fluids formulated with glycol bases other than those listed herein, and all non-glycol Type I deicing/anti-icing fluids, must be tested for endurance times using the methods described in this ARP (as appropriate).
Document requires updating to incorporate a different test surface (composite material). Also, test protocol for frost will be added. Test protocol for artificial snow may or may not be added for this revision. Other minor editorial changes will be made.
