1.1”These practices are to be used for the recording and interpretation of infrared absorption spectra of electrical insulating oils from 4000 cm”’1 to 400 cm”’1 (2.5 ”m 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 comply with the specifications described in Practice E932.
