Historical (view previous versions of standard)
Significance and Use
Crude petroleum contains sulfur compounds, most of which are removed during refining. However, of the sulfur compounds remaining in the petroleum product, some can have a corroding action on various metals, including copper, and this corrosivity is not necessarily related to the total sulfur content. The effect can vary according to the chemical types of sulfur compounds present. This copper foil strip corrosion test is designed to assess the relative degree of corrosivity of a petroleum product towards copper and copper-containing alloys using a shorter test duration than that specified in Test Method D130.
Some sulfur species may become corrosive to copper only at higher temperatures. Thus, higher test temperatures, particularly 100°C (212°F), may be used to test some products by the pressure vessel procedure.
1.1 This test method covers the determination of the corrosiveness to copper of aviation gasoline, aviation turbine fuel, automotive gasoline, natural gasoline, or other hydrocarbons having a vapor pressure no greater than 124 kPa (18 psi), cleaners (for example, Stoddard solvent), kerosine, diesel fuel, distillate fuel oil, lubricating oil, and other petroleum products.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.1, 10.1.1, and Annex A2.
