Jet A-1 Fuel Supplier Jet A-1 is a kerosene grade of fuel suitable for most turbine engine aircraft. Identical with Jet A, it has a flash point minimum of 38 degrees C (100°F) and a freeze point maximum of -47 degrees C. It is widely available outside the U.S.A. The main specifications for Jet A-1 grade (see below) are the UK specification DEF STAN 91-91 (Jet A-1) Nato code F-35, (formerly DERD 2494) and the ASTM specification D1655 (Jet A-1).

Jet A Fuel Supplier Jet A for domestic and international airlines is a kerosene grade fuel, only available in the U.S.A. It has the same flash point as Jet A-1 but a higher freeze point maximum (-40°C). It is supplied against the ASTM D1655 (Jet A) specification.

Jet B Fuel Supplier Jet B is a distillate covering the naphtha and kerosene fractions. A wide-cut type fuel can be used as an alternative to Jet A-1 but because it is more difficult to handle (higher flammability), There is only significant demand in very cold climates where its better cold weather performance is important with lower freeze point and higher volatility being an advantage  for handling and cold starting.  ASTM have a specification for Jet B but in Canada it is supplied against the Canadian Specification CAN/CGSB 3.23

TS-1 Fuel Supplier TS-1 is the main jet fuel grade available in Russian and CIS states. It is a kerosene type fuel with slightly higher volatility (flash point is 28C minimum) and lower freeze point (<-50C) compared to Jet A-1.

American Civil Jet Fuel Supplier Our civil jet fuel specification used in the United States of America is ASTM Specification for Aviation Turbine Fuels D 1655, which defines the requirements for three grades of fuel:-

Jet A for domestic and international airlines.

Jet B with lower freeze point and higher volatility is an advantage for handling and cold starting.

UK Jet Fuel Supplier DEF STAN 91-91 and defines the requirements for a kerosene type fuel (Jet A-1 grade) having a maximum freeze point of -47 degrees C.

Jet A-1 according to the DEF STAN 91-91 specification is very similar to Jet A-1 defined by the ASTM D 1655 except for a small number of areas where DEF STAN 91-91 is more stringent.

Chinese Jet Fuel Supplier The five types of jet fuel that are covered by current Chinese specifications. They are No 1 Jet Fuel, No 2 Jet Fuel etc. RP-I and RP-2. They have a low flash point (minimum 28 degrees C).

RP-1 freeze point is -60 degrees C and RP-2 is -50 degrees C. RP-3 is basically as Western Jet A-1, produced as an export grade. RP-4 is a wide-cut type fuel similar to Western Jet B and Soviet T-2. RP-5 is a high flash point kerosine similar to that used in the West by naval aircraft operating on aircraft carriers. Virtually all jet fuel produced in China is now RP-3 (renamed No 3 Jet Fuel).
