scope:

This International Standard specifies a method for calibrating the kinetic energy scales of Auger electron spectrometers with an uncertainly of 3 eV, for general analytical use in identifying elements at surfaces. In addition, it specifies a method for establishing a calibration schedule. It is applicable to instruments used in either direct or differential mode, if used, is 2 eV peak-to peak. It is applicable to those spectrometres equipped with an inert gas ion gun or other method for sample cleaning with an electron gun cable of operating at 4 eV or higher beam energy.
