Abstract :
Prior methods for evaluating oil for corrosive sulphur content tend to be pass-fail. The method developed at Manitoba Hydro in 2007 and 2008, clearly quantifies the amount of sulphur which reacts with bare copper. In this way, oils can be compared and ranked by the fraction of their sulphur which reacts, or ranked by ppm reactive sulphur content. The test duration and reaction conditions evolved from those of ASTM D1275. The method is explained in detail; a variety of permutations are described, regarding time, temperature and other relevant factors. This is seen as a significant advance in this field.
