AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD
AND SIMILAR USE –
Part 2-5: Particular requirements for automatic electrical
burner control systems
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
international consensus of opinion on the relevant subjects since each technical committee has representation
from all interested National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60730-2-5 has been prepared by IEC technical committee 72:
Automatic controls for household use.
This third edition cancels and replaces the second edition published in 1993, amendment 1
(1996) and amendment 2 (1997) and constitutes a technical revision.
The text of this standard is based on the second edition, amendments 1 and 2 and the
following documents:
FDIS Report on voting
72/430/FDIS 72/447/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.

This part 2-5 is intended to be used in conjunction with IEC 60730-1. It was established on the
basis of the second edition (1993) of IEC 60730-1 and its amendments 1 (1994) and 2 (1997).
Consideration may be given to future editions of, or amendments to, IEC 60730-1.
This part 2-5 supplements or modifies the corresponding clauses in IEC 60730-1 so as to
convert that publication into the IEC standard: Safety requirements for automatic electrical
burner control systems.
Where this part 2-5 states "addition", "modification", or "replacement", the relevant
requirement, test specification or explanatory matter in part 1 should be adapted accordingly.
Where no change is necessary, this part 2-5 indicates that the relevant clause or subclause
applies.
In the development of a fully international standard, it has been necessary to take into
consideration the differing requirements resulting from practical experience in various parts of
the world and to recognize the variation in national electrical systems and wiring rules.
The "in some countries" notes regarding differing national practice are contained in the
following subclauses:
–6.11
– 15.7
– 17.16.102.1
– H.26.9
– H.26.10
– H.26.11
In this publication:
1) The following print types are used:
– Requirements proper: in roman type;
– Test specifications: in italic type;
– Explanatory matter; in small roman type.
2) Subclauses, notes, tables and figures which are additional to those in part 1 are numbered
starting from 101, additional annexes are lettered AA, BB, etc.
The committee has decided that the contents of this publication will remain unchanged until
2002-04. At this date, the publication will be:
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

AUTOMATIC ELECTRICAL CONTROLS FOR HOUSEHOLD
AND SIMILAR USE –
Part 2-5: Particular requirements for automatic electrical
burner control systems
1 Scope and normative references
This clause of part 1 is applicable except as follows:
1.1 Replacement:
This part of IEC 60730 applies to automatic electrical burner control systems for the automatic
control of burners for oil, gas, coal or other combustibles for household and similar use
including heating, air conditioning and similar use.
This part 2-5 is applicable to a complete burner control system and to a separate programming
unit. This part 2-5 is also applicable to a separate electronic high-voltage ignition source and to
a separate flame detector.
Separate ignition devices (electrodes, pilot burners, etc.) are not covered by this part 2-5 unless they are submitted
as part of a burner control system.
Requirements for separate ignition transformers are contained in IEC 60989.
Throughout this part 2-5, where it can be used unambiguously, the word "system" means
"burner control system" and "systems" means "burner control systems".
Systems utilizing thermoelectric flame supervision are not covered by this part 2-5.
1.1.1 This part 2-5 applies to the inherent safety, to the manufacturer's declared operating
values, operating times and operating sequences where such are associated with burner safety
and to the testing of automatic electrical burner control systems used in, on, or in association
with, burners.
Requirements for specific operating values, operating times and operating sequences are given in the standards for
appliances and equipment.
Systems for equipment not intended for normal household use, but which nevertheless may be
used by the public, such as equipment intended to be used by laymen in shops, in light industry
and on farms, are within the scope of this part 2-5.
This part 2-5 applies to systems using NTC or PTC thermistors, additional requirements for
which are contained in annex J.
---------------------- Page: 13 ----------------------
SIST EN 60730-2-5:2002
60730-2-5 IEC:2000 – 11 –
This part 2-5 does not apply to systems designed exclusively for industrial applications.
1.1.2 This part 2-5 applies to manual controls when such are electrically and/or mechanically
integral with automatic controls.
Requirements for manual switches not forming part of an automatic control are contained in IEC 61058-1.
Throughout this part 2-5, the word "equipment" means "appliance and equipment".
1.2 Replacement:
This part 2-5 applies to systems with a rated voltage not exceeding 660 V and with a rated
current not exceeding 63 A.
1.3 Replacement:
This part 2-5 does not take into account the response value of an automatic action of a control,
if such a response value is dependent upon the method of mounting the control in the
equipment. Where a response value is of significant purpose for the protection of the user, or
surroundings, the value defined in the appropriate household equipment standard or as
determined by the manufacturer applies.
This part 2-5 includes systems responsive to flame properties.
1.4 Replacement:
This part 2-5 applies also to systems incorporating electronic devices, requirements for which
are contained in annex H.
1.5 Normative references:
This clause of part 1 is applicable except as follows:
Addition:
