This European Standard was approved by CENELEC on 2007-05-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 62A/550/FDIS, future edition 2 of IEC 60601-1-6, prepared by SC 62A, Common
aspects of electrical equipment used in medical practice, of IEC TC 62, Electrical equipment in
medical practice, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC
as EN 60601-1-6 on 2007-05-01.
The following date was fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-02-01
This European Standard supersedes EN 60601-1-6:2004. However, EN 60601-1-6:2004 remains valid
until all the parts 2 that are used in conjunction with it have been withdrawn. No date of withdrawal of
conflicting national standards (dow) has therefore been fixed. However, when Part 1-6 is used for
appliances not covered by a part 2, EN 60601-1-6:2004 is not to be used after 2009-09-12.
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 60601-1-6 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.
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).
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.

- 3 - EN 60601-1-6:2007
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 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.
