Annotation of standard text ASTM D4171-22 :

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.

Keywords:
additives, aircraft fuel systems, aviation fuels, fuel system icing inhibitors, ice formation,, ICS Number Code 75.160.20 (Liquid fuels)

Additional information

1. Scope

1.1?This specification covers additives for aviation fuels (for example, Specifications D910, D7547, and D1655) used to inhibit ice formation in aircraft fuel systems.

1.2?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3?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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
