Scope

This standard specifies the settings and operating procedures for Fourier transform infrared spectrometers used to monitor in-service oil conditions, including direct trend analysis methods and difference spectrum trend analysis methods. This standard specifies how to use a standard transmis ion cell to obtain the infrared spectrum of oil in use and how to determine the maximum allowable spectral nois . The complete measurement parameters of in-use oil condition monitoring refer to the specific test methods and are not described in this standard. This standard uses International System of Units [SI] units. The units given in brackets are for reference only.
