IEC 60601-2-54:2009 applies to the basic safety and essential performance of medical electrical equipment and medical electrical systems intended to be used for projection radiography and radioscopy. The minimum safety requirements specified in this particular standard are considered to provide for a practical degree of safety in the operation of ME equipment for radiography and radioscopy. Requirements for additional provisions for ME equipment for interventional applications are covered by IEC 60601-2-43. IEC 60601-2-54:2009 has been developed for use with the third edition of IEC 60601-1 (2005). It replaces and supersedes IEC 60601-2-7 and IEC 60601-2-32, as well as IEC 60601-2-28:1993 (currently under revision), all of which were developed to amend earlier editions of IEC 60601-1 and consequently no longer apply to this particular standard.
