NACE TM0172

Abstract

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