IEC60601: understanding the changes from 2nd to 3rd edition

May 22, 2012 // By Peter Blyth, Industry – Medical, XP Power

 The USA version was also published in 2006, but unlike 2nd edition, not by UL. It is published by the American Association for Medical Instrumentation (AAMI) and appears as ANSI/AAMI ES60601_1:2006. Canada published the standard in 2008 as

CAN/CSA60601:2008. Engineers need to be aware that, when using these standards, there are a number of key dates specified for the implementation of the 3rd edition, and that these vary by region.

First published in 1977, the internationally accepted IEC 60601_1 standard has been continuously developed to help alleviate safety issues relating to all manner of medical equipment. The 3rd edition of this medical safety standard was first published by the IEC in 2005 (IEC60601_1:2005) and was adopted by the European Union in 2006 and published as EN60601_1:2006.
