Hi Folks, I'm looking for some more recent definitions/guidelines/criteria for determining what constitutes critical components for the critical component lists in the product technical construction files, in particular the files to be maintained as part of CE compliance. I am not un-familiar with the topic but would like to see what's out there. There are some very old threads regarding this topic in the forum archives so I'm thinking there may be more recent material on this somewhere.
I'm primarily looking for the safety related components. There's a lot of threads on EMC critical components. Certainly any components which improper operation or failure could cause unsafe operation of the product would be critical. Then there is the question of the components that could result in other safety concerns such has fire or stored energy release. In particular would we expect to include individual power supplies of commercial equipment (which typically are either integral with the unit or come with it as an external plug in "brick") that are incorporated into the product in the critical components list for example PC power supplies, display monitor power supplies, printer power supplies. I realize this is a subjective issue so any specific citings, white papers, published guidelines from NRTLs or industry experts, etc. would be more useful than opinion. Thanks David P.
