Aviation Turbine Fuel (Grades JET A and JET A-1)
1.1 This standard applies to two grades of kerosene-type aviation turbine fuel (grades JET A and JET A-1), consisting
entirely of petroleum-derived hydrocarbons, naturally occurring non-hydrocarbons and additives as specified
herein. Kerosene-type aviation turbine fuels are distillates having a minimum flash point of 38°C.
1.1.1 The two grades differ only in freezing point. Grade JET A has a maximum freezing point of -40°C and Grade
JET A-1 has a maximum freezing point of -47°C.
1.2 The fuels are normally used in civil aviation operations.
1.3 Limitations for Use — Aircraft operators should consult their aircraft manuals for the type of fuel, fuel additives
and any temperature-related or other limitations.
1.3.1 Temperature Limitations — When temperatures are close to the fuel freezing-point, fuel operability problems
can be experienced. JET A, with a specification freezing point of -40°C, is not intended for use during extremely
cold weather conditions or when the ambient temperature is close to, or below, -40°C. It also requires more
restrictive use than JET A-1. For more information concerning temperature limitations, see Transport Canada’s
Airworthiness Notice No. B021 (par. 2.1.2) and par. 8.4.
1.4 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.
