This application by Bunker One, is a small practicable tool for look up the ISO 8217 - 2005, 2010/2012, 2017 & 2024 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 -Reproducibility -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 News published on our web page Bunkerone.com will be pushed to the app holders and publish with link to the web under the "news" bar
