Guide to the drafting and use of harmonized and non-harmonized EMC standards
This CENELEC Guide establishes useful guidelines for the preparation and use of standards in the field of electromagnetic compatibility (EMC) in general, and in particular for the implementation of the EMC Directive and the Radio Equipment Directive (RED). This Guide is intended to be used by Technical Committees. The purpose of this guide is to give advice on: - the preparation of dedicated Product and Product Family Standards; - the application of EMC Standards. Certification aspects are not covered by this Guide. NOTE Certification is the action by a third party demonstrating that adequate confidence is provided that a duly identified product, process or service is in conformity with a standard or with other normative documents.
Leitfaden für den Entwurf und die Verwendung von harmonisierten und nicht harmonisierten EMV-Normen
Vodilo za pripravo in uporabo harmoniziranih in neharmoniziranih standardov EMC
Vodilo CENELEC določa smernice za splošno pripravo in uporabo standardov s področja elektromagnetne združljivosti (EMC), predvsem pa za izvajanje direktive o elektromagnetni združljivosti in direktive o radijski opremi (RED). To vodilo je namenjeno tehničnim odborom.
Namen tega vodila je svetovati glede:
– priprave posebnih standardov o proizvodih in družinah proizvodov;
– uporabe standardov elektromagnetne združljivosti.
Vidiki certificiranja niso zajeti v to vodilo.
OPOMBA: Certificiranje je dejanje tretje osebe, s katerim se izkazuje, da določen proizvod, proces ali storitev ustrezno izpolnjuje oziroma je skladna s standardom ali drugimi normativnimi dokumenti.

Foreword
This CENELEC Guide 34:2024 has been prepared by CENELEC Technical Committee CLC/TC 210,
Electromagnetic Compatibility (EMC).
This first edition of CENELEC Guide 34 was approved by the CENELEC Technical Board on
rd
2023-12-13. It supersedes CENELEC Guide 24:2009 (3 edition) ‘Electromagnetic Compatibility (EMC)
rd
Standardization for Product Committees concerned with apparatus’ and CENELEC Guide 25:2009 (3
edition) ‘Guide on the use of standards for the implementation of the EMC Directive to apparatus’.
The main changes in relation to CENELEC Guide 24 and Guide 25 include the following:
1) Change of the Title;
2) In the Introduction, addition of information that the text of this Guide is based on the merging of
Guide 24 and Guide 25, deletion of redundant information;
3) Re-structuring of the document by introduction of Clause 1 “Scope”, Clause 2 “References”, Clause
3 “Terms and definitions, Clause 4 “Types of EMC publications or standards, respectively”, etc.;
4) Update of information, e.g. concerning the European EMC Directive and further inclusion of the
Radio Equipment Directive;
5) Deletion of Clause 9;
6) Shift of definitions from Guide 24, Annex B and Guide 25, Annex B to new Clause 3 and addition of
further definitions;
7) Removal of Annex B stemming from Guide 24 and of Annex B stemming from Guide 25;
8) Removal of Annex C stemming from Guide 24 as it seems that there was no application of this
annex;
9) Addition of a new Annex D concerning radio enabled products / combined equipment;
10) Addition of a new Annex E containing guidance for the preparation of Annexes ZZ for harmonized
European Standards;
11) Editorial improvements.

Introduction
In Europe, Directive 2014/30/EU (EMC Directive (EMCD)) published 2014-03-29 is valid at the time of
publication of this CENELEC Guide. This Directive contains essential requirements for the EMC of
equipment, which it defines as apparatus and fixed installations.
NOTE 1 The essential requirements are set out in Annex I, 1(a) (emission) and 1(b) (immunity) of Directive
2014/30/EU.
In Europe, Directive 2014/53/EU (Radio Equipment Directive (RED)) published 2014-05-22 is also valid
at the time of publication of this CENELEC Guide. This Directive contains essential requirements for
radio equipment including EMC requirements.
NOTE 2 The essential requirements in the field of EMC are set out in Article 3.1(b) of Directive 2014/53/EU.
NOTE 3 Further essential, non-EMC requirements for radio equipment are contained in Article 3.1(a) (safety),
Article 3.2 (efficient use of radio spectrum), Article 3.3 (miscellaneous) and Article 3.4 (Charging capabilities) of
Directive 2014/53/EU.
The essential requirements of these Directives related to electromagnetic compatibility (EMC) can be
divided into electromagnetic emission and immunity requirements.
EMC Directive 2014/30/EU, Article 13, states that equipment which is in conformity with harmonized
standards or parts thereof whose references have been published in the Official Journal of the European
Union (OJEU) shall be presumed to be in conformity with the essential requirements covered by these
standards or parts thereof. The presumption of conformity is limited to the scope of the harmonized
standard(s) applied and the relevant essential requirements covered by the harmonized standard(s).
These harmonized standards can be regarded as tools that can be used for the declaration of conformity
of a product with – here in the field of EMC – essential requirements of the EMC Directive or the Radio
Equipment Directive (depending on which Directive the product falls under).
The European Commission has commissioned CEN, CENELEC and ETSI to draft harmonized
standards for electromagnetic compatibility in support of the EMC Directive and its essential
requirements.
The European Commission has also commissioned CEN, CENELEC and ETSI with the task of
preparing the necessary harmonized standards for the implementation of the essential requirements of
the Radio Equipment Directive in the field of EMC.
This first edition of CENELEC Guide 34 updates the guidance information of CENELEC Guides 24 and
25 with particular focus on the application of Directives 2014/30/EU (EMCD) and 2014/53/EU (RED)
and merges the contents of both Guides.
It is recommended that this CENELEC Guide is read in conjunction with IEC Guide 107.
1 Scope
