JET A-1
Zawartość strony
Characteristic
The JET A-1 aviation fuels is produced from components obtained at a definite technological regimen of hydrodesulphurisation, hydrocracking and distillation. The components meet the rigid quality requirements. The JET A-1 fuel is intended for aviation turbine-type engines.

Notes:
- The requirement is in force at the fuel production site (manufacturer's premises). If the fuel's colour makes it impossible to apply the determination method, the result of visual inspection should be given.
- The requirement is in force at the fuel production site (manufacturer's premises).
- The determination should be carried out only if the fuel contains more than 95% of the hydrated component formed in the high-pressure hydrogen process, i.e. a process where the partial pressure of hydrogen exceeds 7000 kPa (70 bar or 1015 psig). The requirement is in force at the fuel production site.
- Admixture of an anti-oxidation additive is mandatory in hydrorefined and synthetic fuels and must be dosed at the stage of the product leaving the installation, prior to its entering the storage tank, in order to prevent oxidation and formation of resins. The type and concentration of any additives applied must be stated in the Quality Certificate issued by the manufacturer.
