...: biodiesel, viscosity, uncertainty of measurement, metrology Introduction The insertion of biofuels in the international agenda of governments, as an alternative to fossil fuels, relies on some critical factors: (i) environmental pressure for reduction of GHG emissions, (ii) the instability of Manuscript...

..., the uncertainties of measurement were calculated, and the density change with respect to temperature is presented and shown in density variation curves. An analysis of the density variation curves shows that. References Goat Industries , ‘‘ Vegetable Oil as a Diesel Fuel ,’’ http...

... of the classification system may be difficult to ensure as a consequence of the “uncertainty of measurement” associated with the “standard” cone calorimeter test. This would cause a lack of reliability in the classification and could significantly reduce the number and type of products reliably achieving each class...
