scope:

This standard provides a procedure for conducting a test to determine the corrosive properties of gasoline and distillate fuels in preparation for transport through a pipeline. Also included is information on test specimen preparation, equipment, and a system for rating the test specimens.

In this test method, the surface of a cylindrical steel test specimen is prepared and then immersed in a mixture of the test fuel and distilled water. The mixture is stirred and is maintained at a prescribed temperature. The test specimen is then rated by the proportion of test surface that has corroded. Experience has shown that if enough inhibitor is present to produce B+ or better results as defined in this standard, general corrosion in flowing pipelines may be controlled.

This test method does not predict corrosiveness in the standing aqueous phase, nor does it predict microbiological attack.
