Scope

This document specifies the requirements for the identification, evaluation, and correction of unintended damage to the elemental composition or chemical state of samples caused by X-ray irradiation in X-ray photoelectron spectroscopy (XPS) analysis.
This document only applies to unintended damage caused by X-rays, resulting in a decrease or increase in the intensity of photoelectron spectra by less than 30%. This document does not involve comparisons between different types of materials, nor does it address the mechanism, depth, or chemical nature of the damage that occurs.
