If you feel that your comments have not received a fair d12755 you should make your views known to the ASTM Committee on Standards, at the address shown below. The silver corrosion procedure is provided especially for those users who have applications where the insulating liquid is in contact with a silver surface. Awtm extent of deterioration is dependent upon the quantity and type of corrosive agent and time and temperature factors. Flasks of astj capacity are required in order to allow sufficient space d1257 expansion of the oil.
In these cases, the test procedure has become compromised and must be repeated. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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? Detection of these undesirable impurities, even atsm not in terms of quantitative values, is a means for recognizing the hazard involved. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
