This application by Bunker One, is a small practicable tool for look up the ISO 8217 - 2005, 2010/2012 & 2017 standards for residual- and distillate marine fuels.

Programmed calculators are included for different fuel related calculations.


Calculators programmed as below.:

-CCAI Number according ISO 8217

-Cetan Index ASTM - D 976 - 80 (old method)

ASTM - D 4737 - 87 (new method)

-Deviation calculations according Bunker One

-Energy and price relations according Bunker One

-Fuel Blending - Viscosity blending according ASTM - D 7152

Sulphur blending according Bunker One

-Injection temperature according Bunker One

-Specific Energy gross and net content according ISO 8217

-Viscosity Index according ASTM - D 341

-Volume Correction Factor according ASTM D1250-80 Table 5B


General for all calculators is that all entries shall be in SI units. And results also given in SI units.

Where there is a differentiation between Distillates and Residual fuels, distillates are defined with density lower than 900 kg/m3

Where there is a differentiation between Straight Run fuel and Cracked fuels, straight run fuels are defined with density lower than 950 kg/m3
