Following the recently issued standard ASTM D7843 for the detection of Varnish precursors, on June 17th Mecoil is introducing an updated, ASTM-compliant procedure of analysis. Since months, Mecoil was performing correlation tests between the VTI procedure, internally developed in cooperation with other international laboratories, and the new standard method based on CIE LAB color space, obtaining excellent results. According to the new standard, the oil’s tendency to form deposits is estimated using the “DeltaE” index, which measures the difference in the perceived color of the filtering membrane, compared to the virgin membrane, by a spectrophotometric measurement. Mecoil is the first and only Italian laboratory able to run both determinations, quickly and efficiently, in order to provide customers with a more complete and updated report.
