1.1This test method covers the determination of the corrosiveness to silver by automotive spark-ignition engine fuel, as defined by Specification D4814, or similar specifications in other jurisdictions, having a vapor pressure no greater than 124 kPa (18 psi) at 37.8 °C (100 °F), by one of two procedures. Procedure A involves the use of a pressure vessel, whereas Procedure B involves the use of a vented test tube.

1.2The result of the test is based on a visual rating that is classified as an integer in the range from 0 to 4 as defined in Table 1.

1.3The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
