A qualitative method for determining the corrosivity of oils. It mainly determines whether the oil contains active sulfides and elemental sulfur that can corrode metals.
A qualitative method for determining the corrosivity of oils. It mainly determines whether the oil contains active sulfides and elemental sulfur that can corrode metals.
The copper sheet is immersed in the test oil according to the specified method, and the test is deemed successful or unsuccessful based on the change in the color of the copper sheet’s surface.
A qualitative method for determining the corrosivity of oils. It mainly determines whether the oil contains active sulfides and elemental sulfur that can corrode metals. To determine the corrosivity of fuel oil, a polished standard-sized copper sheet is immersed in the oil; after maintaining the specified temperature and time as required by the product specifications, it is removed and its surface color is compared with that of a copper sheet that has not been immersed in the oil. The corrosion level is determined based on the green, black, brownish-black, or steel-gray spots appearing on the oil-soaked test pieces.
The copper sheet is immersed in the test oil according to the specified method, and the test is deemed successful or unsuccessful based on the change in the color of the copper sheet’s surface.

Copper sheet corrosion: A qualitative method that uses copper sheets to directly determine the presence of active sulfur in oils. It is a qualitative method for checking whether engine fuel, jet fuel, or lubricating oil contains active sulfides or free sulfur. The copper sheet is immersed in the test oil according to the specified method, and the test is deemed successful or unsuccessful based on the change in the color of the copper sheet’s surface.
The copper sheet is immersed in the test oil according to the specified method, and the test is deemed successful or unsuccessful based on the change in the color of the copper sheet’s surface.
The copper sheet corrosion test can be used to determine whether the fuel contains active sulfides that can corrode metals.
