_____________
INTRODUCTION TO AMENDMENT 1
The second edition of IEC 60601-2-37 was published in 2007. Since that publication, the
parent standard, IEC 60601-1:2005, entered maintenance, under which an amendment
(IEC 60601-1:2005/AMD1:2012) and a consolidated edition 3.1 (IEC 60601-1:2005 and
IEC 60601-1:2005/AMD1:2012) were published. This amendment to IEC 60601-2-37:2007
addresses three issues:
1) technical changes proposed by National Committees as a result of 4 years of practical
usage,
2) technical and editorial changes resulting from the amended general standard
IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 and its collateral standards
IEC 60601-1-xx, and
3) technical changes as a result of maintenance to normative references.
