John, Thanks for the clarification. Is there any documentation to that affect, or is it common practice to apply the EN transition period to the IEC basic standard that may be called for in the applied generic or ps standard? Also, why do some Generic or PS standards call for the IEC version instead of the EN version, especially if called for from an EN version?

No, it only appears to. Because it's a clone of CISPR 24, its Normative References clause refers to IEC standards. But Annex ZA (not very clearly) replaces those references by the corresponding EN. > Is IEC 61000-4-4 amd. 2 in force > now and should it be used now when EN55024 is the applied standard? > No. The EN transition period applies. Industry cannot work with standards that come into effect instantaneously and without prior notice. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
