This British Standard has been prepared under the direction of the General
Electrotechnical Standards Policy Committee and is the English language
version of EN 50081-1, ‘Electromagnetic compatibility - Generic emission
standard. Part 1 : Residential, commercial and light industry’, published by the
European Committee for Electrotechnical Standardization (CENELEC).
This standard is one of a number of generic standards related to European
Council Directive 89/336/EEC, dated 3 May 1989 (referred to as the
Electromagnetic Compatibility (EMC) Directive), which applies to apparatus
(equipment) liable to cause electromagnetic disturbance or the performance of
which is liable to be affected by such disturbance. It defines the protection
requirements, and related conformity procedures. The protection requirements
state that apparatus within the scope of the Directive are to be so constructed
that:
(a) the electromagnetic disturbance it generates does not exceed a level
allowing radio and telecommunications equipment and other apparatus to
operate as intended;
(b) the apparatus has an adequate level of intrinsic immunity to
electromagnetic disturbance to enable it to operate as intended.
Member States of the EC are required to presume compliance with the
protection requirements where apparatus is in conformity with the relevant
national standard implementing the harmonized standard (in this case
EN 50081-1).
Attention is drawn to Article 10 of the EMC Directive which covers such
matters as declarations of conformity and EC marks.
The following guidance is given to manufacturers intending to make a
declaration of conformity with the protection requirements of Directive
89/336/EEC.
(1) Where a declaration of conformity is to be based exclusively on
standards, a manufacturer should apply all of the standards which have
been listed in the OfSEcial J m m l of the Europeun Cmmunities where
the scopes of those standards are appropriate to the product, but see also
footnote 1to the table on page ii.
(2) Where the scopes of the product-family or product standards listed are
not appropriate to a particular product, the generic standards should be
applied.
(3) Where, for whatever reason, a manufacturer chooses not to apply the
standards or to apply them only in part, the technical construction file
route, as described in Article lO(2) of Directive 89/336/EEC, can be
followed in order to make a declaration of conformity.

The examples of typical equipment given in the table on page ii, which is not
exhaustive, show which standards should be applied if it is intended to make a
declaration of confoimity which is based exclusively on standards.
Although the EMC Directive requires the Member States of the EC to
implement it on 1 January 1992, the EC Commission has proposed an
Amending Directive which would provide a transitional period of 4 years ending
31 December 1995. At the present time, the decision of the Council of Ministers
on the proposal is awaited. During this proposed transitional period,
manufacturers of electrotechniỗal products would have the option either to
comply with the Directive, with effect from 1 January 1992, or to continue to
comply with existing national regulations. Any such national regulations in
force within a Member State before 1January 1992 could continue to apply
until 31 December 1995 when they would have to be repealed. During this
peiiod, products manufactured in one Member State which do not conform to
the Directive would be required to conform to the regulations of the Member
State in which they are marketed.

Information, BSI, Linford Wood, MK14 6LE.
Compliance with a British Standard does not of itself confer immunity
from legal obligations.

GENERIC EMISSION STANDARD
1
Scope
This standard for emission requirements applies to electrical and electronic apparatus intended for
use in the residential, commercial and light-industrial environment, as described in clause 5, for
which no dedicated product or product-family emission standard exists. Apparatus designed to
radiate electromagnetic energy for radio communications purposes is excluded from this standard.
Disturbances in the frequency range O Hz to 400 GHz are covered.
Where a relevant dedicated product or product-family EMC emission standard exists, this shall take
precedence over all aspects of this generic standard.
The emission requirements have been selected so as to ensure that disturbances generated by
apparatus operating normally at residential, commercial and light-industrial locations do not exceed
a level which could prevent other apparatus from operating as intended. Fault conditions of
apparatus are not taken into account.
Apparatus installed in the locations covered by this standard are considered to be directly connected
to low-voltage public mains supplies or to a dedicated DC source which is intended to interface
between the apparatus and the low-voltage public mains supply. Apparatus intended to be
connected to an industrial power network or to special power supply sources are covered by another
generic standard.

Normative references
This European Standard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications are lisfed hereafter. For dated references, subsequent amendments to or revisions of
any of these publications apply to this European Standard only when incorporated in it by
amendment or revision. For undated references the latest edition of the publication referred to
applies.

Objective
The objective of this standard is to define limits and test methods for apparatus defined in the scope,
in relation to electromagnetic emissions which may cause interference in other apparatus e.g. radio
receivers.
These emission limits represent essential electromagnetic compatibility requirements.
Test requirements are specified for each port considered.
NOTE 1: The limits in this standard may not, however, provide full protection against interference
to radio and television reception when the apparatus is used closer than 10 m to the receiving
antenna(e).
NOTE 2: In special cases, for instance when highly susceptible apparatus is being used in
proximity, additional mitigation measures may have to be employedto reducethe electromagnetic
emission further below the specified levels.
4
Definitions
Definitions related to EMC and to relevant phenomena may be found in the EEC Directive, in
chapter 161 of the IEV (IEC 50) and in IEC and CISPR Publications. The definitions stated in the
Directive (89/336/EEC) take precedence.
The following particular definitions are used in this standard:
port: Particular interface of the specified apparatus with the external electromagnetic environment
(see figure 1).
enclosure port The physical boundary of the apparatus through which electromagnetic fields may
radiate or impinge.

Conditions during measurement
The measurements shall be made in the operating mode producing the largest emission in the
frequency band being investigated consistent with normal applications.
An attempt shall be made to maximize the emission by varying the configuration of the test sample.
If the apparatus is part of a system, or can be connected to auxiliary apparatus, then the apparatus
shall be tested while connected to the minimum configuration of auxiliary apparatus necessary to
exercise the ports in accordance with EN 55022.
The configuration and mode of operation during measurement shall be precisely noted in the test
report.
If the apparatus has a large number of terminals, then a sufficient number shall be selected to
simulate actual operating conditions and to ensure that all the different types of termination are
covered.
The tests shall be carried out somewhere within the specified operating environmental range for the
apparatus and at its rated supply voltage, unless otherwise indicated in the basic standard.

Documentation for the purchaserhser
Documentation which shall be supplied to the purchaserhser:
The purchaseduser shall be informed ifspecial measures have to be taken to achieve compliance,
e.g. the use of shielded or special cables.
7.2
Documentation which shall be available to the purchaserhser upon request:
A list of auxiliary apparatus which together with the apparatus comply with the emission
requirements shall be made available.
8
Applicability
Measurements are made on the relevant ports of the apparatus according to table 1. Measurements
shall only be carried out where the relevant ports exist.
It may be determined from consideration of the electrical characteristics and usage of a particular
apparatus that some of the measurements are inappropriate and therefore unnecessary. In such a
case it is required that the decision not to measure be recorded in the test report.
