Foreword
The text of document 62D/857/FDIS, future edition 3 of IEC 60601-2-4, prepared by SC 62D,
Electromedical equipment, of IEC TC 62, Electrical equipment in medical practice, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 60601-2-4 on 2011-01-12.
This European Standard supersedes EN 60601-2-4:2003.
and to implement the decision of IEC SC 62A that the clause numbering structure of particular standards
written to EN 60601-1:2006 would adhere to the form specified in ISO/IEC Directives, Part 2:2004. The
aim of this third edition is to bring this particular standard up to date with reference to the third edition of
the general standard through reformatting and technical changes.
The principle technical changes are as follows:
— 201.8.8.3, test 4: added additional test options;
— Figure 201.105: provided example of stainless steel plates. Added note for 10 Hz generator or
shockable rhythm generator;
— Figure 201.101: Changed orientation of the lower diode at the oscilloscope connection;
— 202.6.1, .2, .4: "Additions" and "Replacements" corrected to be as originally intended;
— 201.101.1: Clarified preconditioning of a non-rechargeable battery;
— 201.3.207: Clarified definition of DUMMY COMPONENT;
— 201.15.4.101: In paragraph b), added reduced flex requirements for sterilizable internal paddles with
specified limit on sterilization cycles;
— 201.15.4.3.103: Added an option for devices having non-changeable pre-programmed energy-setting
sequences;
— 201.102.3.1, 2: Changed from specified defibrillation cycles to use of pre-programmed defibrillation
sequence;
— 202.6.2.2.1: Changed ESD discharge sequence to match EN 60601-1-2:2007.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were 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) 2012-02-12
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-01-12
In this 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 PARTICULAR STANDARD
OR AS NOTED: SMALL CAPITALS.
In referring to the structure of this standard, the term
– “clause” means one of the seventeen numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.);
– “subclause” means a numbered subdivision of a clause (e.g. 7.1, 7.2 and 7.2.1 are all subclauses of
Clause 7).
References to clauses within this standard are preceded by the term “Clause” followed by the clause
number. References to subclauses within this particular 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.
An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates that
there is guidance or rationale related to that item in Annex AA.
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 MDD (93/42/EEC). See Annex ZZ.
Annexes ZA and ZZ have been added by CENELEC.
