Aviation turbine fuel (Grades JET A and JET A-1)
Scope:
This standard applies to two grades of kerosene-type aviation turbine fuel (grades JET A and JET A-1), consisting of conventional hydrocarbons, synthetic hydrocarbons, naturally occurring non-hydrocarbons and additives as specified herein.
The fuels are normally used in civil aviation operations. 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. Kerosene-type aviation turbine fuels are distillates with a minimum flash point of 38°C.
Limitations for use – Aircraft operators should consult their aircraft manuals for the type of fuel, fuel additives and any temperature-related or other limitations.
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. 2.2) and 9.3 in this standard.
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.
