METHOD OF DETERMINING OXIDATION DEGREE OF FULLERENE CONTAINING MATERIAL, METHOD OF DETERMINING OXIDATION DEGREE OF LUBRICANT OIL, LUBRICANT OIL OXIDATION DEGREE DETERMINATION SET, AND DEVICE AND SYSTEM OF DETERMINING OXIDATION DEGREE OF LUBRICANT OIL

Japanese Patent JP2023170374

A

To provide a lubricant oil oxidation degree determination method capable of easily and quickly determining the oxidation degree of lubricant oil including base oil and fullerene, to provide a lubricant oil oxidation degree determination set capable of easily and quickly determining the oxidation degree of lubricant oil including base oil and fullerene, to provide a lubricant oil oxidation degree determination device capable of easily and quickly determining the oxidation degree of lubricant oil including base oil and fullerene, and to provide a system capable of easily and quickly determining the oxidation degree of lubricant oil including base oil and fullerene and of effectively preventing a trouble and a failure of the machine from occurring.SOLUTION: The lubricant oil oxidation degree determination method of determining the oxidation degree of lubricant oil including base oil and fullerene, is characterized by determining the oxidation degree according to the absorption spectrum of the lubricant oil in the UV region. The absorption spectrum in the wavelength of not shorter than 320 nm and not longer than 340 nm is preferably used.SELECTED DRAWING: Figure 12
