Specification of gas oil/diesel oil (MGO)
Diesel oil
Gas oil, marine gas oil (MGO), diesel oil
Gas oil is a crude oil medium distillate and therefore must not contain any
residual materials.
Military specification
Diesel fuels that satisfy the NATO F-75 or F-76 specifications may be used if
they adhere to the minimum viscosity requirements.
Specification
The suitability of fuel depends on whether it has the properties defined in this
specification (based on its composition in the as-delivered state).
The DIN EN 590 standard and the ISO 8217 standard (Class DMA or Class
DMZ) in the current version have been extensively used as the basis when
defining these properties. The properties correspond to the test procedures
stated.
