Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7240-10 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting,
Subcommittee SC 3, Fire detection and alarm systems.
This second edition cancels and replaces the first edition (ISO 7240-10:2007), which has been technically revised.
ISO 7240 consists of the following parts, under the general title Fire detection and alarm systems:

Introduction
A fire detection and fire alarm system is required to function satisfactorily, not only in the event of a fire, but also
during and after exposure to conditions likely to be met in practice, such as corrosion, vibration, direct impact,
indirect shock and electromagnetic interference. Some tests specified in this part of ISO 7240 are intended to
assess the performance of the fire detectors under such conditions.

INTERNATIONAL STANDARD ISO 7240-10:2012(E)
Fire detection and alarm systems —
Part 10:
Point-type flame detectors
1 Scope
This part of ISO 7240 specifies requirements, test methods and performance criteria for point-type, resettable
flame detectors that operate using radiation from a flame for use in fire detection systems installed in buildings.
This part of ISO 7240 is not applicable to flame detectors with special characteristics, developed for specific
risks. It can be used as guidance in assessing other types of flame detectors not included in this part of ISO 7240.
The performance of flame detectors is assessed from results obtained in specific tests. This part of ISO 7240
is not intended to place any other restrictions on the design and construction of such flame detectors.
