Scope

This International Standard specifies methods for calibrating the magnification of scanning electron microscope (SEM) images using appropriate reference substances. This standard is suitable for calibration of magnifications determined by the available range of spacing sizes on calibration reference materials. This standard does not apply to special-purpose length-measuring scanning electron microscopes.
