ARP5945 - Endurance Time Tests for Aircraft Deicing/Anti-icing Fluids SAE Type I

Document Number: ARP5945
Revision Number:
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).
