Active Standard ASTM D4171 | Developed by Subcommittee: D02.J0.04
Book of Standards Volume: 05.02
Historical (view previous versions of standard)
This specification covers additives for aviation fuels used to inhibit ice formation in aircraft fuel systems. Three types of fuel system icing inhibitors are provided as follows: type I - ethylene glycol monomethyl ether, type II - anhydrous isopropanol, and type III - diethylene glycol monomethyl ether. The relative density, color, distillation range, non-volatile matter, and odor shall be tested to meet the requirements prescribed. The water properties, heptanes miscibility, acidity, water miscibility, and flash point shall be tested to meet the requirements prescribed.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
A1.3.1 Fuel system icing inhibitor performance (Type III) is based upon test results using the pure inhibitor in a specific concentration range. Impurities affect inhibitor solubility in the fuel and reduce the effective concentration. Methods are therefore needed to check additive purity to ensure adequate performance in the aircraft.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
