WG 14 - TC 62/SC 62A/WG 14

IEC TR 60601-4-3:2018 is available as IEC TR 60601-4-3:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC TR 60601-4-3:2018 contains a series of recommendations developed by an expert working group of IEC subcommittee 62A in response to questions of interpretation of IEC 60601-1:2005 and related collateral standards in the IEC 60601 series. IEC TR 60601-4-3:2018 is primarily intended to be used by:
– manufacturers of medical electrical equipment;
– test laboratories and others responsible for assessment of compliance with IEC 60601 1:2005, IEC 60601-1:2005/AMD1:2012, IEC 60601-1-8:2006, IEC 60601-1-8:2006/AMD1:2012, IEC 60601-1-11:2010, IEC 60601 1 11:2015 and IEC 60601-1-12:2014;
– those developing subsequent editions of IEC 60601-1.
The recommendations in the first edition of IEC TR 62296 were considered in preparing the third edition of IEC 60601-1. Similarly, it is expected that these recommendations within IEC 60601-4-3 will be considered when preparing future revisions of IEC 60601-1 and related collateral standards in the IEC 60601 series. The object of IEC TR 60601-4-3:2018 is to make the recommendations/interpretations available to those interested in the application of the third edition of IEC 60601-1 and applicable collateral standards. IEC TR 60601-4-3:2018 cancels and replaces the first edition of IEC 60601-4-3 published in 2015. This edition constitutes a technical revision. IEC TR 60601-4-3:2018 includes the following significant technical changes with respect to the previous edition: addition of 47 new recommendations.

IEC TR 60601-4-3:2015(E) is intended to convey the results of WG 14's work to interested parties such as manufacturers and test laboratories while retaining the informative nature of the material. This first edition contains 93 recommendations, numbered 101 to 193. All these recommendations are based upon IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012.

IEC 62353:2014 applies to testing of medical electrical equipment and medical electrical systems, hereafter referred to as ME equipment and ME systems, or parts of such equipment or systems, which comply with IEC 60601-1:1988 (second edition) and its amendments and IEC 60601-1:2005 (third edition) and its amendments, before putting into service, during maintenance, inspection, servicing and after repair or on occasion of recurrent tests to assess the safety of such ME equipment or ME systems or parts thereof. For equipment not built to IEC 60601-1 these requirements may be used taking into account the safety standards for the design and information in the instructions for use of that equipment. This standard contains tables with allowable values relating to different editions of IEC 60601-1. For the purpose of this standard, the application of measuring methods is independent of the edition according to which the ME equipment or ME system is designed. This standard contains "general requirements", which contain clauses of general concern, and "particular requirements", further clauses handling special types of ME equipment or ME systems and applying in connection with the "General requirements". This standard is not suitable to assess whether ME equipment or ME systems or any other equipment comply with the relevant standards for their design. This standard is not applicable to the assembly of ME systems. For assembling ME systems see Clause 16 of IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:2012. This standard does not define requirements for repair, exchange of components and modification of ME equipment or ME systems. All maintenance, inspection, servicing, and repair done in accordance with the manufacturer's instructions maintain the conformity to the standard used for the design of the equipment. Otherwise conformity to applicable requirements should be assessed and verified, before the tests of this standard are performed. This standard is also applicable to tests after repair. This second edition cancels and replaces the first edition of IEC 62353 published in 2007. This edition constitutes a technical revision including the following main revisions:
- clarification in 5.3.4.1 that measurements of leakage currents based on test configurations derived from IEC 60601-1 are an allowable alternative method and the inclusion of informative explanation in Annex A;
- revision of the protective earth resistance requirements for ME systems using multiple socket outlets to take account of IEC 60601-1:2005/AMD1:2012 on the safe allowed values of protective earth resistance of plugged-in equipment;
- the inclusion of expected minimum insulation resistance values in Table 2; and
- a reordering of the sequence of testing in Annex B.

IEC/TR 62354:2009(E) provides guidance on general testing procedures according to IEC 60601-1:1988, IEC 60601-1-1:2000 and IEC 60601-1:2005. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. Several tests have been updated and additional test procedures and informative annexes added.
This technical report is to be read in conjunction with  IEC 60601-1:1988, IEC 60601-1-1:2000 and IEC 60601-1:2005.

IEC/TR 62296:2009(E) contains a series of recommendations developed by an expert working group of IEC subcommittee 62A in response to questions of interpretation of the second edition of IEC 60601-1. IEC/TR 62296:2009(E) is primarily intended to be used by:
- manufacturers of medical electrical equipment;
- test houses and others responsible for assessment of compliance with IEC 60601-1:1988, and
- those developing subsequent editions of IEC 60601-1.
The recommendations in the first edition of IEC/TR 62296 were considered in preparing the third edition of IEC 60601-1. As the third edition of IEC 60601-1 has been published, some of the recommendations in the second edition of IEC/TR 62296 have been changed to align with requirements in IEC 60601-1:2005. Seven additional recommendations have been developed by IEC/SC 62A/WG 14 and are included in this edition of IEC/TR 62296. They are recommendations 57 through 63. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. This edition includes seven new recommendations: Recommendations 57 through 63. As the third edition of IEC 60601-1 has been published, some of the recommendations in this edition have been changed to align with requirements in IEC 60601-1:2005.
