SCOPE 1.1 Form This foundation specification (AMS1424N) and its associated category specifications (AMS1424/1 and

14、 AMS1424/2) cover a deicing/anti-icing material in the form of a fluid. 1.1.1 Foundation and Category Specifications This foundation specification establishes the requirements for all Type I deicing/anti-icing fluids and defines Glycol (Conventional and Non-Conventional) based and Non-Glycol based f

15、luids and contains additional properties and requirements that apply to both Glycol (Conventional and Non-Conventional) and Non-Glycol based products. 1.2 Application The fluid is generally used heated either diluted with water, or as supplied, for the removal of deposits of frost, ice, and snow on

16、exterior aircraft surfaces prior to take off. 1.2.1 Consult aircraft manufacturers maintenance manual and service letters to determine any restrictions relating to the use of deicing/anti-icing fluids for type and model of aircraft being treated. Refer to AS6285. 1.2.2 The manufacturer shall determi

17、ne and report the Lowest Operational Use Temperature (LOUT) for the recommended dilutions of their fluid(s). 1.2.2.1 The LOUT for an SAE Type I fluid is the lowest temperature at which the fluid has been tested and certified in accordance with the appropriate aerodynamic acceptance tests (3.5.3) whi

18、le maintaining the 18 F (10 C) freezing point buffer (refer to ARP4737). 1.3 Precautions 1.3.1 The deicing/anti-icing formulation may be mildly toxic and contact with human skin and eyes should be avoided. Prolonged exposure to concentrations of vapor and wind-borne mists should be avoided. Consult

19、the manufacturers Safety Data Sheet for further information. 1.3.2 A fluid meeting all other requirements of this specification may not meet the aerodynamic acceptance test in the concentrated form. This fluid shall only be used diluted to the ratios which meet the aerodynamic acceptance test criter

20、ia. 1.3.3 The fluid shall have a minimum flash point of 212 F (100 C) and should be used with extreme care when applied in the immediate vicinity of heaters or engine exhausts. 1.3.4 Caution should be exercised in the use of glycol-water deicing/anti-icing solutions in and around aircraft electrical

21、/electronic circuitry with noble metal (including silver) coated wiring or terminals which could come into contact with the fluid. Exothermic reactions, which may result in fire, have been reported. This may occur where defectively insulated wires, switches, or circuit breakers carrying direct curre

22、nt are encountered. Deicing/anti-icing fluids which are based on glycols shall contain an inhibitor to minimize this potential fire hazard (3.1). 1.3.5 Slippery conditions may exist on the ground or on equipment following deicing/anti-icing procedures. 1.3.6 A fluid meeting this specification is uni

23、que to the manufacturer and may be adversely affected by mixing with other aircraft deicing/anti-icing fluids. Adverse effects may also result from the mixing of Glycol (Conventional and Non-Conventional) based and Non-Glycol based aircraft deicing/anti-icing fluids and should be tested prior to use

24、. Users of AMS1424/1 and AMS1424/2 Type I fluids shall ensure that the Type I fluid is compatible with the SAE AMS1428 Type II, Type III, or Type IV fluid that is used in combination with the Type I fluid. SAE INTERNATIONAL AMS1424N Page 4 of 17 1.3.7 At the option of the user, the manufacturer shal

25、l demonstrate the fluid as supplied or at intended use dilution and heated to intended use temperature, applied through a commercial deicing/anti-icing vehicle system to an inclined flat or curved surface, preferably an aircraft wing or horizontal stabilizer, at pressures and flow rates normal for i

26、ntended use, does not cause foam which does not rapidly collapse, and fluid surface shall not have the appearance of snow or slush. Observe fluid for wetting, film breaks, crawling or fisheyes. Observe how long the sprayed film is continuous and how long it remains on the aircraft wing leading edge

27、without breaks. 1.3.8 Deicing/anti-icing fluids should be compatible with carbon brake material. Refer to AS6285 and the airplane manufacturers maintenance and service documents for further information on fluid use. The industry standard test method for compatibility is AIR5567. 1.4 Safety - Hazardo

28、us Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address any hazards which may be involved in such use. It is the sole responsibility of the user to ensure fami

29、liarity with the safe and proper use of any hazardous materials and processes and to take necessary precautionary measures to ensure the health and safety of all personnel involved. 2.
