Doug - Firstly, I do not think that the EN has been listed in the Official Journal (OJ) and so cannot be used (yet) to show compliance with the EU EMC Directive.
As far as test plans go, they are required by the IEC 801 and EN61000 series of immunity specs (look in the Test Procedure section of the specs). It would be nice to think that manufacturers are already testing to a test plan - how else does the test engineer know what is a pass and what is a fail for susceptibility testing ?? The next version of the residential/commercial/light industrial generic immunity spec will also have the -2,-3,-4,-5,-6,-8 and -11 requirements. If a new product is within the scope of EN61326 it is probably worthwhile testing to it rather than the generic specs once EN61326 is listed in the OJ. The emissions requirements of EN61326 distinguish Class A equipment from Class B equipment (i.e. same definitions as EN55011 and EN55022). If currently testing to the generic standard then emissions limits for equipment used in light-industrial and commercial locations are the same as Class B limits. Testing to EN61326 will be easier than the generics for products that are used exclusively in light industrial/commercial environments. The emissions requirements are specified at a test distance of 10m - the 30m test requirement of CIPSR 11/EN55011 for Class A is avoided. I only have the IEC version so cannot give you the dop and dow. I was under the impression that, for EN standards, the dow and dop were to be detailed in the Official Journal listing and not in the specificaiton itself. Does anyone know if this is happening ?
