Foreword
This European Standard was prepared by a joint working group of CLC/TC 205, Home and Building
Electronic Systems (HBES) and CEN/TC 247, Building Automation, Controls and Building Management
(BACS). It was submitted to the formal vote and was approved by CENELEC as EN 50491-5-2 on
2010-04-01.
1)
This standard supersedes the relevant parts of EN 50090-2-2:1996 ; it is referenced by CEN/TC 247
and CLC/TC 205.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-04-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-04-01
As a result of the discussions at the CLC/TC 205 meeting on 2004-10-5/6 concerning the structuring of
their standards in general parts and open system parts (see CLC/TC 205/Sec0413/INF) the following new
parts of EN 50491 under the generic title “General requirements for Home and Building Electronic
Systems (HBES) and Building Automation and Control Systems (BACS)“ under the task of the
JWG CEN/TC 247–CLC/TC 205 are proposed:
Part 2 Environmental conditions;
Part 3 Electrical safety requirements;
2)
Part 4-1 Functional safety requirements (for non safety related systems);
2)
Part 4-2 Functional safety requirements (for safety related systems);
Part 5-1 EMC requirements, conditions and test set-up;
Part 5-2 EMC requirements for HBES/BACS used in residential, commercial and light industry
environment;
Part 5-3 EMC requirements for HBES/BACS used in industry environment.
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive EMC Directive 2004/108/EC. See Annex ZZ.

Introduction
EN 50491 series deals with developing and testing Home and Building Electronic Systems (HBES) and
Building Automation and Control System (BACS).
The expression HBES/BACS covers any combination of HBES and/or BACS products including their
separate connected/detachable devices linked together via one or more networks.
Part 5 of this series applies to HBES/BACS devices to ensure a common level of EMC requirements.

a
The test shall be carried out at the frequencies appropriate to the power supply frequency. Equipment intended for use in areas
supplied only at one of these frequencies need only be tested at that frequency.
b
Applicable only to apparatus containing devices susceptible to magnetic fields.
c
For CRTs, the acceptable jitter depends upon the character size and is calculated for a test level of 1 A/m as follows:
()3C +1
J =
where jitter J and character size C are in millimetres.
As jitter is linearly proportional to the magnetic field strength, tests can be carried out at other test levels extrapolating the
maximum jitter level appropriately.
d
EN 61000-4-20 may be used for small EUTs as defined in EN 61000-4-20:2003, 6.1.
e
The test level specified is the r.m.s. value of the unmodulated carrier.
f
If the test is passed with the higher level and performance criteria A the test for the lower level is not necessary.
g
Except for the ITU broadcast frequency bands 87 MHz to 108 MHz, 174 MHz to 230 MHz and 470 MHz to 790 MHz, where the
level shall be 3 V/m and the performance criteria A.
h
The frequency range has been selected to cover the frequencies with the highest potential risk of disturbance.
