(Test Method)Standard Test Method for Rapid Determination of Corrosiveness to Copper from Petroleum Products Using a Disposable Copper Foil Strip
Standard Test Method for Rapid Determination of Corrosiveness to Copper from Petroleum Products Using a Disposable Copper Foil Strip
SIGNIFICANCE AND USE
4.1 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.
4.2 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.
SCOPE
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.
1.2.1 Exception—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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.1, 10.1.1, and Annex A2.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
This test method is similar in nature to the Test Method D130 test method, but involves three major
differences. Firstly, a single-use copper foil strip is used in place of the Test Method D130 multi-use
copper strip. Secondly, a different polishing technique is used in preparing the copper foil strip, which
uses a commercially available scouring-pad in place of the initial and final polishing techniques
described in Test Method D130. Thirdly, this test method involves a shorter analysis time of 45 min
for all product types as compared to the Test Method D130 method requirements, which are longer;
for example, two or three hours.
