Specifies particular requirements for the safety of high voltage X-ray generators. It is based on but not equivalent to and reproduced from IEC 60601-2-7:1998 with additional requirements for Australia and New Zealand provided in an appendix. This Standard refers to its Parent Standard, AS/NZS 3200.1.0:1998. An available copy of AS/NZS 3200.1.0 is essential to the meaningful interpretation of this part.

Addition:This Particular Standard applies to HIGH-VOLTAGE GENERATORS of medical diagnostic X-RAY GENERATORS that operate between 10 kV and 400 kV and in which the electric energy for LOADING an X-RAY TUBE is derived from alternating current SUPPLY MAINS without an essential element of energy storage within the equipment.Note. - An essential element of energy storage is considered not to exist if the energy for LOADING at the LOADING FACTORS defining the NOMINAL ELECTRIC POWER is delivered from the SUPPLY MAINS during LOADING.This Particular Standard applies to:- dental HIGH-VOLTAGE GENERATORS;- sub-assemblies of HIGH-VOLTAGE GENERATORS;- HIGH-VOLTAGE GENERATORS that are integrated with an X-RAY TUBE ASSEMBLY;- HIGH-VOLTAGE GENERATORS of radiotherapy treatment simulators.In this Particular Standard, references to equipment "specified for dental applications" apply only to equipment with NOMINAL X-RAY TUBE VOLTAGES not exceeding 125 kV. For equipment operating above 125 kV the other requirements of this Particular Standard apply without regard to whether dental applications are specified.Where necessary, requirements for X-RAY GENERATORS are given but only where these concern the functioning of the associated HIGH-VOLTAGE GENERATOR.This Particular Standard excludes- equipment for RECONSTRUCTIVE TOMOGRAPHY;- equipment that is battery operated.Rationale. - Requirements to be observed for the equipment excluded from the scope have not been sufficiently investigated. In order not to delay the issue of this Particular Standard such equipment is excluded for the time being.Consideration of those requirements may later allow them to be given as an addendum to this Particular Standard; otherwise they will be dealt with in stand-alone Particular Standards of Part 2 of Publication 601.
