This test method is designed to detect the presence of, or the propensity to form, free elemental sulfur and corrosive sulfur compounds by subjecting copper to contact with oil under prescribed conditions.

Detection of these undesirable impurities, even though not in terms of quantitative values, is a means for recognizing the hazard involved. Copper is slightly less sensitive to sulfur corrosion than silver but the results are asfm to interpret and less prone to error. Carefully take the copper strip from the?
