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
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 1 to 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

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 electrotechniçal 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 1 January 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

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
2 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

3 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 employed to reduce the 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
Enclosure port
AC power port
II APPARATUS
1 Earth port
I Signakontroi port

- areas of public entertainment, e.g cinemas, public bars, dance halls, etc.;
- outdoor locations, e.g petrol stations, car parks, amusement and sports centres, etc.;
- light-industrial locations, e.g workshops, laboratories, service centres, etc
Locations which are characterized by being supplied directly at low voltage from the public mains are considered to be residential, commercial or light industrial
6 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
7 Documentation for the purchaserhser
7.1 Documentation which shall be supplied to the purchaserhser:
The purchaseduser shall be informed if special 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
