Standard Test Method for Corrosiveness to Copper from Petroleum Products by Copper Strip Test

This test method determines the corrosiveness to copper of selected petroleum products by heating a polished copper strip in the sample and evaluating its tarnish or corrosion.

ASTM D130-26 describes the copper strip test for assessing the relative corrosiveness of aviation and automotive gasoline, aviation turbine fuel, Stoddard solvent, kerosine, diesel fuel, distillate fuel oil, lubricating oil, natural gasoline, and other qualifying hydrocarbons. It covers equipment, reagents, sample handling, copper strip preparation, test procedures, result classification, reporting, and precision information. The method uses product-specific time and temperature conditions and compares the tested strip with the ASTM Copper Strip Corrosion Standards.

Application Scope: Petroleum testing laboratories and fuel, lubricant, and hydrocarbon quality control programs evaluating copper corrosiveness.
