I don't see how a solid-state relay could be certified to IEC 60950-1. 
It is not a component safety standard, with a few specific exceptions, 
and solid-state relays don't seem to be one of those special cases.

I have heard however that there is a new IEC standard being released 
for solid state relays and therefore we should request these relays to 
be certified against the new standard rather than IEC60950-1 in the 
future.

Can anyone enlighten me with details of this new standard please?  What 
is the standard number, when is it to be published, and when will 
relays certified against IEC60950-1 no longer be accepted by test 
houses?

Abstract: States the characteristics of solid-state relays; the

Hello Craig,

I believe the new standard is IEC 62314 published last year.
http://webstore.iec.ch/preview/info_iec62314%7Bed1.0%7Den.pdf

The information I have from CENLEC on EN 62314:2006 is that the date of
announcement was October 1, 2006.  The proposed date of publication is
April 1, 2007 and the proposed date of withdrawal is July 1, 2009.

Good morning all,


We use 240V solid state relays in some of our products, certified to
IEC60950-1 and UL508.  I have heard however that there is a new IEC
standard being released for solid state relays and therefore we should
request these relays to be certified against the new standard rather than
IEC60950-1 in the future.


Can anyone enlighten me with details of this new standard please?  What is
the standard number, when is it to be published, and when will relays
certified against IEC60950-1 no longer be accepted by test houses?


Thanks and regards,


Craig
