This test method covers the determination of the corrosiveness
to copper of aviation gasoline, aviation turbine fuel,
automotive gasoline, cleaners (Stoddard) solvent, kerosine,
diesel fuel, distillate fuel oil, lubricating oil, and natural
gasoline or other hydrocarbons having a vapor pressure no
greater than 124 kPa (18 psi) at 37.8°C. (Warning—Some
products, particularly natural gasoline, may have a much
higher vapor pressure than would normally be characteristic of
automotive or aviation gasolines.
