Foreword
This document (EN 230:2005) has been prepared by Technical Committee CEN/TC 47 “Atomizing oil burners
and their components-Function-safety-testing”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by December 2005, and conflicting national standards shall be withdrawn
at the latest by June 2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 230:1990.
According to edition 1990 the following fundamental changes are carried out:
 protection against environmental influences;
 additional requirements for complex electronics.
 the structure and wherever possible the definitions and requirements are taken over from EN 298:2003-
09.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and the United Kingdom.
Introduction
Whilst this document is written primarily for Automatic Oil Burner Control Systems used on or in appliance for
cooking, heating, hot water production, refrigeration, lighting or washing and having, where applicable, a normal
water temperature not exceeding 105 °C, it may be usefully quoted, as a whole or in part, by standards for other
equipment.
The functional characteristics of the automatic burner control systems, programming units, and their associated
flame detector devices, in so far as they are not laid down in this document, are given by the standards for the
appliances for which the automatic burner control systems are intended.
This document deals with immunity aspects of Electromagnetic Compatibility (EMC) only. Since automatic
burner control systems are intended for use as an integrated or incorporated part of an appliance, further EMC
tests (both immunity and emission) may be required for the intended use.
1 Scope
This document specifies the requirements, operating conditions and test methods for burner control systems for
automatic and semi-automatic oil burners with or without fans.
It also applies to dual fuel burners, for use with either oil or gaseous fuels, when operating on oil.
This document covers type testing only.
This document also applies to automatic burner control systems, programming units or flame detector devices
that include additional functions.
Automatic burner control systems utilising thermo-electric flame supervision devices are not covered by this
document.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
flame detector device
device by which the presence of a flame is detected and signalled;
it can consist of a flame sensor, an amplifier and a relay for signal transmission. These parts, with the possible
exception of the actual flame sensor, can be assembled in a single housing for use in conjunction with a
programming unit
[EN 298:2003, term 3.1]
3.2
flame sensor
actual flame-sensing element, the output signal or value of which is used as the input for the flame detector
amplifier
[EN 298:2003, term 3.2]
3.3
sensed flame and flame signal
3.3.1
sensed flame
physical value monitored by the flame sensor

present
[EN 298:2003, term 3.4]
3.5
programming unit
unit which reacts to signals from control and safety devices, gives control commands, controls the start-up
sequence, supervises the burner operation and causes controlled shut-down, and if necessary safety

stage, where the system is not in lock-out position, has not yet received the start signal but can proceed with
the start-up sequence when required;
at this stage, the output terminals for any automatic shut-off valve and ignition device are not energised
