CISPR 16-2-3:2016 is available as <a href="https://webstore.iec.ch/publication/25875">CISPR 16-2-3:2016 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.<br />
<br />
CISPR 16-2-3:2016 specifies the methods of measurement of radiated disturbance phenomena in the frequency range of 9 kHz to 18 GHz. The aspects of measurement uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2. It has the status of a basic EMC publication in accordance with IEC Guide 107, "Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications". This fourth edition edition cancels and replaces the third edition published in 2010, its Amendment 1:2010 and its Amendment 2:2014. This edition constitutes a technical revision.

Specifikacija merilnih naprav in metod za merjenje radijskih motenj in odpornosti - 2-3. del: Metode za merjenje radijskih motenj in odpornosti - Merjenje sevanih motenj
Ta del standarda CISPR 16 določa načine merjenja radiofrekvenčnih motenj v frekvenčnem območju od 9 kHz do 18 GHz. Vidiki merilne negotovosti so določeni v standardih CISPR 16-4-1 in CISPR 16-4-2.
OPOMBA: V skladu z vodilom IEC 107 [13]1 je standard CISPR 16-2-3 osnovna objava o elektromagnetni združljivosti, ki jo uporabljajo tehnični odbori v okviru Mednarodne elektrotehniške komisije (IEC). Kot je navedeno v vodilu 107, so za ugotavljanje uporabe standarda o elektromagnetni združljivosti odgovorni tehnični odbori. Odbor CISPR in njegovi pododbori so pripravljeni sodelovati s tehničnimi odbori pri vrednotenju posameznih preskusov elektromagnetne združljivosti za ustrezne izdelke.

Radiated disturbance measurements
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 National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard CISPR 16-2-3 has been prepared by CISPR subcommittee A: Radio-interference measurements and statistical methods. This fourth edition edition cancels and replaces the third edition published in 2010, its Amendment 1:2010 and its Amendment 2:2014. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: addition of content on correction of the electric field strength to account for phase centre of log-periodic dipole array antennas.

[13]1, CISPR 16-2-3 is a basic EMC publication for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of the EMC standard. CISPR and its subcommittees are prepared to co-operate with product committees in the evaluation of the value of particular EMC tests for specific products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
