Product Code:SAE AS5900
Title:Standard Test Method for Aerodynamic Acceptance of SAE AMS 1424 and SAE AMS 1428 Aircraft Deicing/Anti-icing Fluids
Issuing Committee:G-12adf Aircraft Deicing Fluids
Scope:This SAE Aerospace Standard (AS) establishes the aerodynamic flow-off requirements for SAE AMS 1424 Type I and SAE AMS 1428 Type II, III and IV fluids used to deice and/or anti-ice aircraft:a. with takeoff rotation speeds exceeding approximately 100 knots, with time from brake release to rotation speed greater than 20 s, typical for large transport type jet aircraft. This procedure is referred to as the High Speed Ramp Test.and/orb. with takeoff rotation speeds exceeding approximately 60 knots, with time from brake release to rotation speed greater than 15 s typical for commuter type aircraft. This procedure is referred to as the Low Speed Ramp Test.NOTE: When compensating measures, such as increase in rotation speed, are used in the aircraft takeoff procedure, the High Speed Ramp can apply. The objective of this standard is to ensure acceptable aerodynamic characteristics of the deicing/anti-icing fluids as they flow off aircraft lifting and control surfaces during the takeoff ground acceleration and climb.NOTE: These test methods are based on glycol-based fluids, additional testing may be required for non-glycol-based fluids.
