A New Approach for Calculating the Carbon-Type Composition of Insulating Oils of Petroleum Origin Bellingham + Stanley Application Note XAUK LAB201-01 0316 The measurement of refractive index is commonplace within petrochemical and associated industries and its determination is cited in many technical documents and standard test methods such as ASTM D 2140 that describes “Standard Practice for Calculating Carbon-Type Composition of Insulating Oils of Petroleum Origin.” However, refractive index measurement forms only part of the overall experiment and once other parameters have been...

A New Approach for Calculating the Carbon-Type Composition of Insulating Oils of Petroleum Origin ASTM D 2140 requires measurement of it's viscosity, density, relative density (specific gravity) and refractive index in order to calculate the viscosity-gravity constant (VGC) and refractivity intercept (n) prior to using a three dimensional correlation graph to determine carbon-type composition of insulating oils. The use of a correlation graph is likely to lead to some variation, caused by operator error visually interpreting the Software installed in RFM900-T Series refractometers allows...
