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.
