2012-06-01 This European Standard supersedes EN 60601-1-2:2001 and its amendment A1:2006.
This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 93/42/EEC. See Annex ZZ. This European Standard constitutes a collateral standard to EN 60601-1:2006, hereafter referred to as the general standard. This EN 60601-1-2 was revised to structurally align it with EN 60601-1:2006 and to implement the decision of IEC SC 62A that the clause numbering structure of collateral standards written to EN 60601-1:2006 would adhere to the form specified in ISO/IEC Directives, Part 2:2004. The principle technical changes are in Clause 4, which now recognizes that there is a general requirement for a risk management process in EN 60601-1:2006. In the 60601 series of publications, collateral standards specify general requirements for safety applicable to – a subgroup of MEDICAL ELECTRICAL EQUIPMENT (e.g. radiological equipment); or – a specific characteristic of all MEDICAL ELECTRICAL EQUIPMENT, not fully addressed in the general standard (e.g. alarm systems). In this collateral standard the following print types are used: − requirements and definitions: in roman type; − test specifications: in italic type; − informative material appearing outside of tables, such as notes, examples and references: in smaller type. Normative text of tables is also in a smaller type; − TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS COLLATERAL STANDARD OR AS NOTES: IN SMALL CAPITALS. NOTE Defined terms are not printed in SMALL CAPITALS in Table 1 through Table 8, in the tables in Annex C and in statements required to appear in the technical description or instructions for use because they are intended for the OPERATOR or RESPONSIBLE ORGANIZATION, who may not be familiar with the defined terms of EN 60601 standards. In referring to the structure of this standard, the term – “clause” means one of the six numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Clause 6 includes Subclauses 6.1, 6.2, etc.); –
“subclause” means a numbered subdivision of a clause (e.g. 6.1, 6.2 and 6.2.1 are all subclauses of Clause 6). SIST EN 60601-1-2:2008

- 3 - EN 60601-1-2:2007 References to clauses within this standard are preceded by the term “Clause” followed by the clause number. References to subclauses within this standard are by number only.
In this standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of the conditions is true. The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2. For the purposes of this standard, the auxiliary verb: − “shall” means that compliance with a requirement or a test is mandatory for compliance with this standard; − “should” means that compliance with a requirement or a test is recommended but is not mandatory for compliance with this standard; − “may” is used to describe a permissible way to achieve compliance with a requirement or test. Clauses, subclauses, items and definitions for which a rationale is provided in informative Annex A are marked with an asterisk (*). Annexes ZA and ZZ have been added by CENELEC. __________ The contents of the corrigendum of March 2010 have been included in this copy. SIST EN 60601-1-2:2008

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International standard IEC 60601-1-2 has been prepared by IEC subcommittee 62A: Common aspects of electrical equipment used in medical practice, of IEC technical committee 62: Electrical equipment in medical practice. This third edition constitutes a collateral standard to IEC 60601-1: Medical electrical equipment – Part 1: General requirements for safety and essential performance hereafter referred to as the general standard. This document cancels and replaces the second edition of IEC 60601-1-2, and constitutes a technical revision. SIST EN 60601-1-2:2008

– 6 – 60601-1-2 © IEC:2007 This edition of IEC 60601-1-2 was revised to structurally align it with the 2005 edition of IEC 60601-1 and to implement the decision of IEC subcommittee 62A that the clause numbering structure of collateral standards written to IEC 60601-1:2005 would adhere to the form specified in ISO/IEC Directives, Part 2:2004. The principle technical changes are in Clause 4, which now recognizes that there is a general requirement for a risk management process in IEC 60601-1:2005. The text of this standard is based on the following documents: FDIS Report on voting 62A/560/FDIS 62A/567/RVD
Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. In the 60601 series of publications, collateral standards specify general requirements for safety applicable to: – a subgroup of MEDICAL ELECTRICAL EQUIPMENT (e.g. radiological equipment); or – a specific characteristic of all MEDICAL ELECTRICAL EQUIPMENT, not fully addressed in the general standard (e.g. alarm systems). In this collateral standard, the following print types are used: – requirements and definitions: roman type. – test specifications: italic type. – informative material appearing outside of tables, such as notes, examples and references: in smaller type. Normative text of tables is also in a smaller type. – TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS COLLATERAL STANDARD OR AS NOTED: SMALL CAPITALS. NOTE Defined terms are not printed in SMALL CAPITALS in Table 1 through Table 8, in the tables in Annex C and in statements required to appear in the technical description or instructions for use because they are intended for the OPERATOR or RESPONSIBLE ORGANIZATION, who may not be familiar with the defined terms of IEC 60601 standards. In referring to the structure of this standard, the term – “clause” means one of the six numbered divisions within the table of contents, inclusive of all subdivisions (e.g. Clause 6 includes 6.1, 6.2, etc.); – “subclause” means a numbered subdivision of a clause (e.g. 6.1, 6.2 and 6.2.1 are all subclauses of Clause 6). References to clauses within this standard are preceded by the term “Clause” followed by the clause number. References to subclauses within this standard are by number only. In this standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of the conditions is true. The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part 2. For the purposes of this standard, the auxiliary verb: − “shall” means that compliance with a requirement or a test is mandatory for compliance with this standard; SIST EN 60601-1-2:2008

– 8 – 60601-1-2 © IEC:2007 INTRODUCTION The need for establishing specific ELECTROMAGNETIC COMPATIBILITY standards for MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS is well recognized. In particular, the existence of ELECTROMAGNETIC EMISSION standards is essential for the protection of: − safety services; − other MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS; − electrical equipment that is not ME EQUIPMENT (e.g. computers); − telecommunications (e.g. radio/TV, telephone, radio-navigation). Of even more importance, the existence of ELECTROMAGNETIC IMMUNITY standards is essential to assure safety of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS. ELECTROMAGNETIC COMPATIBILITY (see Definition 3.4) differs from other aspects of safety covered by IEC 60601-1 because the electromagnetic phenomena exist, with varying degrees of severity, in the normal use environment of all MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS and by definition the equipment must “perform satisfactorily” within its intended environment in order to establish ELECTROMAGNETIC COMPATIBILITY. This means that the conventional single fault approach to safety is not appropriate for application to ELECTROMAGNETIC COMPATIBILITY standards. The ELECTROMAGNETIC DISTURBANCE environment can be compared to ambient temperature, humidity and atmospheric pressure. MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS may experience environmental conditions within the expected range at any time, and for extended periods of time. As with atmospheric pressure and humidity, the OPERATOR of the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM may not be aware of ambient levels on a continuous basis. The IMMUNITY TEST LEVELS specified in this collateral standard (IEC 60601 TEST LEVELS) represent the range found in the general medical use environment. Therefore, under these conditions, the performance of the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM would also be expected to be normal. MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS are used in the practice of medicine because they provide needed FUNCTIONS. If MEDICAL ELECTRICAL EQUIPMENT or a MEDICAL ELECTRICAL SYSTEM does not provide its needed FUNCTION, because of a lack of IMMUNITY to events expected in the normal use environment, this interferes with the practice of medicine and cannot be considered an acceptable situation. This edition recognizes that there is a shared responsibility between MANUFACTURERS, RESPONSIBLE ORGANIZATIONS and OPERATORS to ensure that MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS are designed and operated as intended. The MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM MANUFACTURER’S responsibility is to design and manufacture to meet the requirements of this collateral standard and to disclose information to the RESPONSIBLE ORGANIZATION or OPERATOR so that a compatible ELECTROMAGNETIC ENVIRONMENT can be maintained in order that the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM will perform as intended. SIST EN 60601-1-2:2008

60601-1-2 © IEC:2007 – 9 –
Because the practice of medicine involves many specialities, there will by necessity be MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS that are designed to perform a variety of FUNCTIONS. Some FUNCTIONS involve, for example, measurement of signals from a PATIENT that are of very low levels when compared to ELECTROMAGNETIC NOISE levels that can be coupled into MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS during the ELECTROMAGNETIC IMMUNITY testing specified in this collateral standard. Because of the proven benefits of many such MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, this collateral standard allows the IMMUNITY TEST LEVELS to be lowered, provided there is sufficient justification based on physical, technological or physiological limitations. In this case, the MANUFACTURER is required to disclose the levels at which the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM meets the performance requirements of this collateral standard and to specify the characteristics of the ELECTROMAGNETIC use environment and how this environment is established, in which the MEDICAL ELECTRICAL EQUIPMENT or MEDICAL ELECTRICAL SYSTEM will perform as intended. This collateral standard also recognizes that for certain environments, higher IMMUNITY LEVELS may be required. Research necessary to determine how to identify the environments that may require higher IMMUNITY LEVELS, as well as what the levels should be, is in progress.
Finally, this collateral standard recognizes that for LIFE-SUPPORTING MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, higher levels of IMMUNITY are necessary in order to establish a broader safety margin, even for use in the general medical use environment. Therefore, this collateral standard specifies additional requirements for LIFE-SUPPORTING MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS. This collateral standard is based on existing IEC standards prepared by subcommittee 62A, technical committee 77 (electromagnetic compatibility between electrical equipment including networks) and CISPR (International special committee on radio interference). The ELECTROMAGNETIC COMPATIBILITY requirements specified by this collateral standard are generally applicable to MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS as defined in 3.63 and 3.64 in the general standard. For certain types of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS, these requirements may need to be modified by the special requirements of a particular standard.
