The copper strip corrosion test is a simple way to assess how corrosive a petroleum product is due to active sulfur compounds. It's commonly used to test lubricants for turbines, gearboxes, and hydraulic systems. The test involves immersing a polished copper strip in a sample of the product for three hours at a certain temperature, depending on the type of oil being tested. The strip is then examined for signs of degradation, and rated on a scale from 1A (barely noticeable tarnish) to 4C (severe corrosion). This test is effective at detecting corrosive effects on copper alloys but not on iron or ferrous alloy components.
Our High Temperature Biobased Grease is characterized by its super high viscosity index base oil and lithium complex thickener, which improves thermal shear stability and load capacity. It contains no heavy metals or other harmful or environmentally undesirable additives, and is Ultimately Biodegradable. It meets and exceeds the performance requirements of ASTM D-4950, copper strip corrosion test.
Applications: Industrial and mining machinery, transportation, agricultural, construction and forestry equipment, paper mills, conveyors, journal bearings, electric motors, pumps and marine applications can all benefit from its long lasting protection.
