CAN/CGSB-3.24-2023

1 Scope This National Standard of Canada applies to three grades of aviation turbine fuel (military grades F-34, F-37 as its equivalent, and F-44) consisting of conventional hydrocarbons, synthetic hydrocarbons, naturally occurring non-hydrocarbons and additives as specified herein. Grade F-34 is a kerosene-type aviation turbine fuel, and grade F-44 is a high-flash kerosene-type aviation turbine fuel. Kerosene-type aviation turbine fuels are distillates with a minimum flash point of 38 °C and high-flash type aviation turbine fuels are distillates with a minimum flash point of 60 °C. Grade F-37 is equivalent to grade F-34 with the addition of an approved thermal stability additive. This standard describes three military grade fuels normally used in aviation and naval operations whose product quality parameters are influenced by international military standardization agreements. F-34, F-37 and F-44 are North Atlantic Treaty Organization (NATO) code numbers for products conforming to this standard. Limitations for use – Aircraft operators should consult their aircraft manuals for the type of fuel, fuel additives or other limitations. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. Units of measurement – Quantities and dimensions in this standard are provided in metric units from the International System of Units (SI units). This standard expresses the industry standard nominal units of measurement in North America of “% by mass” and “% by volume”. The SI equivalent expressions for these units are “% m/m” and “% V/V” respectively.
