interpretation of infrared absorption spectra of electrical insulating oils from 4000 to 400 cm-1 (2.5 to 25 m). Note 1 - While these practices are specific to ratio recording or optical null double-beam dispersive spectrophotometers, single-beam and HATR (horizontal attenuated total reflectance), Fourier-transform rapid scan infrared spectrophotometers may also be used. By computerized subtraction techniques, ratio methods can be used. Any of these types of equipment may be suitable if they co
