This standard applies to two types of middle distillate fuel, Type 11 and Type 15 (corresponding to military grades F-76 and F-75 respectively), that are suitable for marine (naval) applications such as gas turbine power plants, highspeed and medium-speed internal combustion engines of the compression-ignition type, and boilers. Fuel produced to this standard is not intended for use in aircraft turbine engines.

This standard describes two military grade fuels normally used in naval operations whose product parameters are influenced by international military standardization agreements. F-76 and F-75 are NATO code numbers for products conforming to this standard. It may also be suitable for non-military use.

Type 11 is intended for equipment operating at an ambient temperature of -1°C or above. This grade is the primary fuel for naval requirements.

Type 151 is intended for use in equipment operating at an ambient temperature above -12°C.

Subject to purchaser approval, for designated DND vessels in non-combat use, CAN/CGSB-3.517 or CAN/CGSB- 3.520 may be applicable for use. Other marine vessel users outside of the Department of National Defence may refer to ISO 8217, which include grades that allow up to 7.0 volume % of Fatty Acid Methyl Ester(s) (FAME).

See Annex B for regulations that apply to diesel fuels.
