International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 62041:2010
Title Safety of transformers, reactors, power supply units and combinations thereof - EMC requirements
Project Number 22377
Abstract/Scope IEC 62041:2010 applies to transformers, reactors, power supply units and combinations thereof covered by the IEC 61558 series of standards. This standard deals with the electromagnetic compatibility requirements for emission and immunity within the frequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencies where no requirement is specified. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the frequency range for tests according to IEC 61000-4-3 has been extended above 1 GHz according to technologies used in this frequency area; - the testing requirements according to IEC 61000-4-11 have been amended significantly; - the inclusion of a clause on tests in series production; - the inclusion of a new clause on measurement uncertainly, and - the inclusion of requirements on DC power ports and telecommunication ports. It has the status of a product family EMC standard in accordance with IEC Guide 107:2009, Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication. In the meantime, the previous edition can still be ordered by contacting your local IEC member National Committee or the IEC Central Office.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
