Hello all, I'm confused. When preparing an EMC test plan for CE requirements I've been told to narrow in on Generic or Product Standards (which ever is more applicable) to help demonstrate compliance. For example, if testing to EN 55024 ITE immunity, the standard calls for various IEC Basic Standards to be carried out. The severity levels to be perfromed on the EUT is given in the EN 55024 tables.
I've always been told that: - The level called out in the Generic/Product standard takes precedent over the the informative- recommended sevrity levels (for a given environment,level 1-4 etc)in the IEC Basic's - The Basic's are only to be used for set-up and how to perfrom the test. Here's the question: In the ESD and Surge standard there is mention in the test methodology that "lower levels" shall be applied (I don't see this in the EFT, Rad Susc. or Cond RF standards). I have heard comments that only the one set of levels called out in the Generic/Product standard is all that needs to be performed. Then I've also been told from other camps that lower levels MUST be carried out. If the EN 55024 calls for 1,2 kV for surge on the AC, does this mean we have to repeat the test @ .5, 1kV too? For ESD, 8 air, 4 cont should really be 8,6,4,2 air and 4,2,1 cont?? Any guidance would be appreciated. __________________________________________________ Do You Yahoo!?
