INTRODUCTION
This amendment contains a first series of revisions to IEC 60601-1-2 (second edition, 2001):
Medical electrical equipment – Part 1-2: General requirements for safety – Collateral
standard: Electromagnetic compatibility – Requirements and tests.
This amendment deals primarily with requirements for EQUIPMENT and SYSTEMS that:
• comply with CISPR 11 Group 2 Class B except for the third harmonic of the fundamental
frequency;
• are for use by healthcare professionals;
• are not intended for sale to the general public; and
• are intended for use in domestic establishments or connected to the PUBLIC MAINS
NETWORK.
However, this amendment also includes several other corrections and additions to IEC
60601-1-2:2001.
To meet needs for change that were identified by users of this Collateral Standard, it was
necessary to amend the standard before the previously approved maintenance cycle date.

3.201.2 Essential performance
Replace the existing text of this subclause with the following:
Either the essential performance of the EQUIPMENT or SYSTEM shall be identified (see Annex
GGG for guidance on identifying the essential performance) or the performance of all
FUNCTIONS of the EQUIPMENT or SYSTEM shall be considered essential performance for the
purpose of IMMUNITY testing (see 36.202.1 j)). The essential performance shall be disclosed in
the ACCOMPANYING DOCUMENTS.
Compliance is checked by inspection of the ACCOMPANYING DOCUMENTS or, if this identification
is not performed, by inspection of the documents to verify that the performance of all
FUNCTIONS of the EQUIPMENT or SYSTEM has been tested in accordance with 36.202.
3.201.4 Non-medical electrical equipment
Remove the asterisk from the title and replace the existing text of this subclause with the
following:
Non-medical electrical equipment that is supplied as part of a SYSTEM is exempt from the EMC
testing requirements of this standard, provided all of the following conditions are met (see
also Annex HHH):
a) the non-medical electrical equipment complies with applicable international EMC
standards;
b) both the EMISSIONS and IMMUNITY of the non-medical electrical equipment have been
determined not to adversely affect the essential performance or safety of the SYSTEM;
c) the EMISSIONS of the non-medical electrical equipment have been determined not to cause
the EMISSIONS of the SYSTEM to exceed applicable limits.
Compliance is checked by inspection of the documents for this determination and other
appropriate documents or certificates or, if this determination is not performed, by inspection
of the documents to verify that the non-medical electrical equipment has been tested in
accordance with this standard.
Add the following new subclause:
*3.201.5 General test conditions
For EMC testing, the SINGLE FAULT CONDITION requirements of the General Standard do not
apply.
