ASTM D – 15 – Standard Test Method for Corrosive Sulfur in Electrical Insulating Liquids
Inch-pound units are included for informational purposes. Strips may be stored in sulfur-free ast, at this point for future use. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
A description of the tarnish levels is provided in Table 2 for reference only.
The extent of deterioration is dependent d12755 the quantity and type of corrosive agent and time and temperature factors. If the oil visibly darkens during testing then most likely oxygen has entered the vessel and oxidized the oil.
Bubble nitrogen through the oil in the? This test method is designed to detect the presence of, or the propensity to form, free s1275 sulfur and corrosive sulfur compounds by subjecting copper to contact with oil under prescribed conditions. The presence of elemental sulfur or corrosive sulfur compounds will result in deterioration of these metals and cause conductive or high resistive films to form.
ASTM D1275 – 15
If a specimen is borderline or unclear, take a clean laboratory tissue and drag it across the surface with heavy pressure; if any of the deposited material is removed, the deposit is corrosive and is to be reported as such.
This is the preferred method. Light orange, almost the same as freshly polished strip b. d12275
Detection of these undesirable impurities, even though not in terms of quantitative values, is a means for recognizing the hazard involved. Rub in the direction of the long axis of the strip. Method A is the one that has been in place since Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend.

Do not use compressed air or an inert gas to dry the copper strip.
Interpretation of Results Clean all metal dust and abrasive from the strip, using successive clean cotton pads until a fresh pad remains unsoiled. Do not use pressurized air to dry copper strip. A circulating hot-air oven is preferred. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
Flasks of such capacity are required astn order to allow sufficient space for expansion of the oil. A number in parentheses indicates the year of last reapproval. Wipe the strip with fresh pads of cotton and subsequently handle only with stainless steel forceps do not touch with the?
