Petroleum Testing
Corrosion
Test for corrosion are of a qualitative type and are made to ascertain wheter fuel oils are free of a tendency to corrode copper fuel lines and brass or bronze parts used in the burner assemblies. The copper strip corrosion test is conducted by immersing a polished copper strip in a sample of fuel contained in a chemically clean test tube. The tube is then placed in a bath maintained at a temperature of 50°C. After washing, the strip is then examined for evidence of corrosion and judged by comparisons with the corrosion scale as reflected in the ASTM Copper Strip Corrosion Standards.
