What does the term “Essential Performance” means? It is quite literally referring to which functions of the product are considered essential.

According to IEC 60601-1: performance of a clinical function, other than that related to BASIC SAFETY, where loss or degradation beyond the limits specified by the MANUFACTURER results in an unacceptable RISK. ESSENTIAL PERFORMANCE is most easily understood by considering whether its absence or degradation would result in an unacceptable RISK. Does using either 2nd or 3rd edition make any device less safe? Are there any benefits to 3rd compared to 2nd? The test levels required by both the 2nd and 3rd editions of IEC 60601-1-2 are the same. The main change was in clause 4, where 3rd edition recognizes that IEC 60601-1:2005 implements a risk management process. For this reason, while the test levels are the same, the objective of the testing and what is being monitored may be different in a 2nd and 3rd edition test report.

If it can be shown that the 2nd edition testing covered all aspects of basic safety and essential performance identified in the 3rd edition risk management file, then the 2nd edition report can be used to show compliance with the 3rd edition requirements on that basis. Actual device safety will vary from device to device and will depend on how robust the risk management file is in regards to EMC phenomena. For devices approved in 2009 with 60601-1 do we have to test for rev 3 in the US for FDA an in other countries like in Europe? What would be the rev 3 requirements at present for devices cleared in 2009?
