This method is for determining the smoke point of kerosene and aviation turbine fuel utilizing an automated instrument with a camera capable of digitalizing the flame image. Smoke point is defined as the maximum height, in millimeters, of a smokeless flame of fuel burned in a wick-fed lamp of specified design. In general, higher aromatic concentration of a fuel will produce a shorter flame height, while low aromatic concentration will produce a higher flame height with lower smokeproducing tendency. The automated method demonstrates improved precision and removes analyst subjectivity of visually observing flame height by manual smoke point methods.
