Copper Strip Corrosion Test Tube Bath
The Copper Strip Corrosion Test Tube Bath provides constant temperature immersion for copper strip tarnish testing of petroleum products that do not require a test bomb. This 20-tube capacity bath is designed for testing diesel fuel, fuel oil, automotive gasoline, Stoddard solvent, kerosene, and lubricating oil. The unit features welded stainless steel inner wall construction with a powder coated steel outer wall and built-in support rack, all fully insulated for temperature stability.
Safety and Protection
An overtemperature control circuit automatically interrupts power to the unit should bath temperature exceed a programmed cut-off point, protecting both operator and equipment during extended testing operations.
Test Method Overview
The Copper Strip Tarnish Test assesses the relative degree of corrosivity of petroleum products, including aviation fuels, automotive gasoline, natural gasoline, solvents, kerosene, diesel fuel, distillate fuel oil, lubricating oil and other products. A polished copper strip is immersed in 30 mL of sample at elevated temperature. After the test period, the strip is examined for evidence of corrosion and a classification number from 1-4 is assigned based on a comparison with the ASTM Copper Strip Corrosion Standards.
