EN 55024 is based on CISPR 24. CISPR 24 uses dated references to the IEC 61000-4-X series. As such, the specified versions apply. There is nothing written in EN 55024 that would update these dated references, so my interpretation would be that the old versions still apply. This is a problem as you must contact the IEC to obtain the older versions (they are available I’m told, just not on the web site).

CENELEC Guide n 25, Guide on the use of Standards for the implementation of the EMC Directive... Regarding 61000-4-4: ..." When the new edition will be published, the edition dated 1995 will still be valid up to 2007-10-01 but It is always better to use the most recent version of a standard as soon as it is available.", Paco Cabeza-Lopez |Communications Manager <mailto:|i...@cenelec.org> |i...@cenelec.org ,|www.cenelec.org (the emphasis is mine, not Paco's -- MH) As an additional note, our customers began asking for compliance to the newly published IEC versions BEFORE they were published. Of course, on the IEC side, the old version is by definition obsolete and no longer availabl: Only the 2004 version of 61000-4-4 exists according to IEC.....

An EN standard may however, reference a CISPR or IEC standard to be used. Limits and test conditions should be taken from the EN standard, however. In general however, it’s the manufacturer that should decide what standard is applicable to a product. A test house however, will give you a founded advice on what standard should cover your product to obtain compliance. If you still want to test according to a different standard / date / version the test house may refuse to cosign a DoC. There is a tendency to leave out dated references in harmonized standards, in which case a test house will select the latest published valid version of a referenced standard.

Thanks for your help. What standards dates and amendments apply within EN55024? Is it those listed standards dates that are in section 2. Normative References? What do we apply, IEC's or EN's? Is it always better and justified to apply the latest revisions of IEC or EN? Do we have the option of IEC's or EN's? Thank You and Best regards Alex ________________________________________________________________________ This email has been scanned for all known viruses and appropriate content by the Messagelabs mail service. ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
