of the EMC directive to apparatus
INTRODUCTION
The EMC Directive, 2004/108/EC states that a presumption of conformity with the protection
requirements (emission and immunity) related to EMC shall exist for all apparatus in
conformity with those harmonised standards (ENs) that are identified as relevant by
publication of their reference numbers in the Official Journal of the European Union (OJEU).
The presumption of conformity is limited to the scope of the harmonised standard(s) applied
and the relevant protection requirements covered by the harmonised standard(s).
This third edition of Guide 25 updates the guidance in the light of the application of Directive
2004/108/EC, and updates the references to the standards.

Edition 3 / December 2009 5
CENELEC Guide 25 Guide on the use of standards for the implementation
of the EMC directive to apparatus
1 General principles
Conformity with the harmonised standards listed in the Official Journal (OJEU) of the
European Union (generic and product standards i.e. product-family or dedicated product
standards) provides a presumption of conformity with the protection requirements of EMC
Directive 2004/108/EC (covering emission and immunity). Harmonised standards are thus
designed to satisfy the protection requirements of the EMC Directive.
The complete list of harmonised standards published in OJEU under the EMC-directive may
be found on the following website of the European Commission:
http://ec.europa.eu/enterprise/electr_equipment/emc/stand.htm
Standards may be used to demonstrate compliance with all the protection requirements (this
means, if applicable, low-frequency as well as high-frequency phenomena, emission as well
as immunity) or may be used to cover them only in part. Where harmonised standards are
not applied, or are not applied in full, the technical documentation required by Annex II of the
Directive must include an electromagnetic compatibility assessment of the apparatus, on the
basis of the relevant phenomena, for those aspects not covered by the parts of the
harmonised standards applied (if any).
The simplest route to compliance is for a manufacturer to use standards that cover the whole
of the EMC protection requirements of the Directive, in which case the manufacturer has to
apply all the normative EMC requirements of those standards listed in the OJEU whose
scopes are applicable to the individual product.
In the absence of appropriate product standards i.e. product-family or dedicated product
standards in the OJEU list, the generic standards shall be applied to show compliance.
When showing compliance through standards it is often necessary to comply with more than
one standard. This is because some EMC standards do not cover the whole EMC domain
covered by the EMC Directive. They may concern only immunity (e.g. EN 61547) high-
frequency emission (e.g. EN 55014-1, EN 55011, EN 55015, etc.) or low frequency emission
phenomena (e.g. EN 61000-3-2, EN 61000-3-3).
When dedicated product standards are listed either for emission or immunity, the directly
corresponding product family standards do not normally apply as well, except when referred
to in the dedicated standards.
2 Application to typical equipment
With a view to helping manufacturers, the following non-exhaustive Table 1 shows, for some
examples of typical equipment, those standards to apply to cover the protection requirements
of the EMC Directive. All the standards on the horizontal line, corresponding to a category of
equipment, must be applied to demonstrate presumption of conformity by application of
harmonised standards.

of the EMC directive to apparatus
This table reflects only the situation at the date of publication of this CENELEC Guide. It will
be updated in subsequent editions of the Guide.
Note that this table is indicative only. The definitive list of standards that are applicable under
the EMC Directive is published in the Official Journal of the European Union. The reference
to the Commission website where the latest list may be viewed or downloaded as a .pdf file
is given in Clause 1 of this Guide. Note that the .pdf file of the relevant OJEU pages is
definitive, and the list on the web page is provided for information only, and has no legal
validity.
3 Criteria for selecting standards
Selecting a particular product standard for application to a given product may sometimes
give difficulties.
The following series of six basic principles will help in the selection of appropriate standards:
1) The scopes of the product-family or dedicated product standards govern their
applicability to individual products. The scopes of the standards should therefore be
considered carefully, with all their implications. In case of doubt (which may still arise
with very broad scope definitions in product-family standards) a second principle (see
item 2 following) may be useful.
2) It is the intended use and function of the equipment that determines the EMC standards
to be applied.
EXAMPLE:
A washing machine, whatever communication or microprocessor modules are used in it,
remains basically classified as household equipment for the application of standards and
therefore EN 55014-1 and EN 55014-2 apply.
3) Particular interface modules in well-defined equipment (e.g. washing machines) may
have to comply with additional requirements that are not included in the normally
applicable product-family standard for the complete product. In this case, the interface
module (separated or not from the complete apparatus) shall comply with additional
requirements for the port corresponding to the interface module only.
NOTE It may be advisable to include at a later stage requirements for connection ports to public and/or
private telecommunication lines in both generic and product (family) standards. This would make the
problem easier by avoiding the need to resort to additional standards.
4) The scopes of EN 55011, EN 55013, EN 55014, EN 55015 and EN 55022, for radio-
interference emission limitation, are in general mutually exclusive. This means that only
one of them has to be selected for given single function equipment to comply with the
protection requirements of the EMC Directive.

5) Despite these general principles, borderline problems may still occur that are difficult to
solve. For multifunction apparatus, it may be necessary to comply with more than one
standard for emission and/or immunity. See Annex D for further information.
6) EN 61000-3-2 and EN 61000-3-3 are published in the OJEU as product family
standards, and apply in their own right to all products in the scope of these standards.
It is intended that generic and product (- family) standards should make reference to the
basic standards without repeating their detailed contents. Basic standards do not contain
requirements and therefore a declaration of conformity of products with the basic standards
has no significance. Thus basic standards are not included in the list of harmonised
standards published in the Official Journal of the European Union (OJEU). This OJEU list will
indeed include only those standards permitting the direct presumption of conformity of
products with Directive 2004/108/EC.
Alternative test and measurement methods, when introduced into a harmonised standard for
the same purpose are considered, together with their associated limits, as equivalent
regarding the provision of a presumption of conformity with the protection requirements.
