IEC 60601-1-3

Applies to X-ray equipment and to subassemblies of such equipment, where radiological images of a human patient are used for diagnosis, planning or guidance of medical procedures. The object of this collateral standard is to establish general requirements for protection against X-radiation in X-ray equipment, in order that the irradiation of the human patient, the operator, staff and members of the public can be kept as low as reasonably achievable, without jeopardizing the benefit of the radiological procedure.
