John, Amendment A1:2000 to EN55022:1998 changes subclause 10.4, Equipment set-up, for tabletop units. Their linecords are now to come straight down from the tabletop, then go through ferrite clamps or ferrite tubes before they plug into the AC power outlet.
According to the latest listing of harmonized standards for the EMC Directive, in the March 26, 2003 Official Journal of the European Union (C74 Volume 46 pages 1-18, which you can download from http://europa.eu.int/eur-lex/en/dat/2003/c_074/ c_07420030326en00010017.pdf) EN 55022:1998+A1:2000 is still scheduled to take effect August 1. We've had some extended discussions on the EMC-PSTC mailing list in the last few months about: * These clamps. * Whether you can make your own versus buying them. * The reasons for this amendment. I have been recommending to our clients for the last six months that if they have older products with internal AC power supplies, or that use "brick" external power supplies, that: * We need to run (rerun) the Radiated Emissions test to A1:2000 if they want to import the products into Europe after August 1. OR * They need to obsolete, or get any remaining units imported into Europe, before August 1.
