EN 55011:2009 – 2 – Foreword The text of document CISPR/B/478/FDIS, future edition 5 of CISPR 11, prepared by CISPR SC B, Interference relating to industrial, scientific and medical radio-frequency apparatus, to other (heavy) industrial equipment, to overhead power lines, to high voltage equipment and to electric traction, was submitted to the IEC-CENELEC parallel vote. A draft amendment (FprAA) covering common modifications towards the future edition 5 of CISPR 11 (CISPR/B/478/FDIS), prepared by the Technical Committee CENELEC TC 210, Electromagnetic compatibility (EMC), was submitted to the formal vote. The combined texts were approved by CENELEC as EN 55011 on 2009-09-01. This European Standard supersedes EN 55011:2007 + A2:2007. This EN 55011:2009 got a more transparent structure, introduces another set of particular limits for conducted and radiated disturbances of "heavy duty" general purpose equipment of class A group 1 with a rated input power in excess of 20 kVA, in accordance with the needs of the industries and refers to the full approach in respect of the measurement instrumentation uncertainty specified in CISPR 16-4-4. Furthermore, any kind of "legal statements" were removed from the normative main body of this European Standard. The following dates were fixed: – latest date by which the EN
has to be implemented at national level by publication of an identical national standard or by endorsement
(dop)
2010-09-01 – latest date by which the national standards conflicting with the EN have to be withdrawn
(dow)
2012-09-01 This European Standard has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 2004/108/EC. See Annex ZZ. Annexes ZA, ZB and ZZ have been added by CENELEC. ____________ SIST EN 55011:2010



– 3 – EN 55011:2009 The main content of this standard is based on CISPR Recommendation No. 39/2 given below: RECOMMENDATION No. 39/2 Limits and methods of measurement of electromagnetic disturbance characteristics
of industrial, scientific and medical (ISM) radio-frequency equipment The CISPR CONSIDERING a)
that ISM RF equipment is an important source of disturbance; b) that methods of measuring such disturbances have been prescribed by the CISPR; c)
that certain frequencies are designated by the International Telecommunication Union (ITU) for unrestricted radiation from ISM equipment, RECOMMENDS that the latest edition of EN 55011 be used for the application of limits and methods of measurement of ISM equipment. SIST EN 55011:2010



EN 55011:2009 – 4 – Endorsement notice The text of the International Standard CISPR 11:2009 was approved by CENELEC as a European Standard with agreed common modifications as given below. COMMON MODIFICATIONS 4 Frequencies designated for ISM use Replace by: 4 National measures and frequencies designated for ISM use Certain frequencies are designated by the International Telecommunication Union (ITU) for use as fundamental frequencies for ISM RF applications (see also definition 3.1). These frequencies are listed in Table 1. Table 1 – Frequencies in the radio-frequency (RF) range designated by ITU

Outside of ITU designated ISM bands the limits for the disturbance voltage and radiation disturbance in this standard apply. b Resolution No. 63 of the ITU Radio Regulations applies. In some CENELEC countries different or additional frequencies may be designated for use with ISM RF applications in the meaning of the definition found in the ITU Radio Regulations, see definition 3.1. These frequencies are listed in Table ZB.1 (see Annex ZB). The limits for the disturbance voltage and radiation disturbance defined in this standard do also not apply to the fundamental ISM frequencies listed in Table ZB.1. If ISM RF applications use fundamental frequencies other than the ITU or nationally designated frequencies, then the limits for the disturbance voltage and radiation disturbance of this standard apply also to these fundamental frequencies.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC N
