Introduction
The purpose of a flame detector is to warn person(s) within or in the vicinity of a building of the
occurrence of a fire emergency in order to enable such person(s) to take appropriate measures.
Flame detectors respond to the flickering ultra-violet or infra-red signal produced from burning
hydrocarbons. Flame detectors might be better suited to applications where heat and smoke sources
are present e.g. aircraft hangars or oil rigs.

This European Standard allows manufacturers to specify the range of the flame detector in terms of
the distance over which it can detect a flaming fire. Four ranges are defined and these are tested by
measuring the response of the flame detector to test fires at a fixed minimum and at the maximum
range as declared by the manufacturer. As contaminants on the window(s) could inhibit the
transmission of the radiation from a flame to the sensor(s) a window monitoring facility test has been
introduced, as an option with requirements, in order to check whether the function operates.

This European Standard gives common requirements for the construction and robustness of flame
detectors as well as for their performance under climatic, mechanical and electrical interference
conditions which are likely to occur in the service environment. Flame detectors are classified in one
of two application environment types, i.e. Type A and Type B. More severe climatic conditions are
applied to devices that are primarily intended for outdoor applications (Type B) than those primarily
intended for indoor applications (Type A)
1 Scope
This European Standard specifies requirements, test methods and performance criteria for point-type,
flame detectors that operate using radiation from a hydrocarbon flame for use in fire detection
systems installed in and around buildings.
Flame detectors having special characteristics suitable for the detection of specific fire risks are not
covered by this standard (although the standard may be used as guidance in assessing such
products). The performance requirements for any additional functions are beyond the scope of this
standard (e.g. additional features or enhanced functionality for which this standard does not define a
test or assessment method).

Unless otherwise stated in a test procedure, the testing shall be carried out after the test specimen
has been allowed to stabilize in the standard atmospheric conditions for testing as described in
IEC 60068-1 as follows:
a) temperature : (15 to 35) °C
b) relative humidity : (25 to 75) %
c) air pressure : (86 to 106) kPa
prEN 54-10:2012 (E)
NOTE If variations in these parameters have a significant effect on a measurement, then such variations
should be kept to a minimum during a series of measurements carried out as part of one test on one specimen.
5.1.2 Operating conditions for tests
If a test method requires a specimen to be operational, then the specimen shall be connected to
suitable supply and monitoring equipment with characteristics as required by the manufacturer's data.
Unless otherwise specified in the test method, the supply parameters applied to the specimen shall be
set within the manufacturer's specified range(s) and shall remain substantially constant throughout the
tests. The value chosen for each parameter shall normally be the nominal value, or the mean of the
specified range. If a test procedure requires a specimen to be monitored to detect any alarm or fault
signals, then connections shall be made to any necessary ancillary devices (e.g. through wiring to an
end-of-line device for conventional detectors) to allow a fault signal to be recognised.
Unless otherwise specified in the test method, detectors having adjustable sensitivity shall be set to
their highest sensitivity for the conditioning.
NOTE The details of the supply and monitoring equipment and the alarm criteria used should be given in the
test report.
5.1.3 Mounting arrangements
The specimen shall be mounted by its normal means of attachment in accordance with the
manufacturer's instructions. If these instructions describe more than one method of mounting then the
method considered to be most unfavourable shall be chosen for each test.
5.1.4 Tolerances
If a specific tolerance or deviation limit is not specified in a requirement or test procedure a deviation
limit of ± 5 % shall be applied.
5.1.5 Determination of response point
5.1.5.1 Principle
The response point shall be measured by exposing the detector to the radiation from a suitable flame
source and determining the greatest distance at which the detector will reliably produce an alarm
condition within a time of 30 s.
5.1.5.2 Test apparatus
The test apparatus shall be as described in annex A.
The design and construction of the apparatus, and the surfaces surrounding the test area, shall be
such that no significant radiation from the source reaches the detector apart from that which has
passed through the aperture. (This means for example that there shall be no reflection of radiation
from the walls or other parts of the apparatus, and no spurious radiation from hot flue gases or hot
surfaces around the burner.)
Throughout this test method it is necessary to align the detector relative to its optical axis and to
measure distances relative to the plane of the detector sensing element(s). If the detector does not
have a well-defined optical axis then the manufacturer shall nominate an optical axis for the purposes
of this test method. The position of this axis relative to an easily identifiable plane on the detector shall
be noted in the test report.
Similarly, if the detector sensing elements do not lie in a well-defined plane then the manufacturer
shall nominate a plane for the purposes of this test method. The position of this plane relative to an
easily identifiable plane on the detector shall be noted in the test report.
prEN 54-10:2012 (E)
5.1.5.3 Initial determination
A suitable area for the aperture shall be determined experimentally before the commencement of the
test programme such that the response point of one detector, chosen at random from the specimens
submitted for test, lies within the range 1300 mm to 1700 mm. The size and shape of the aperture
used shall be recorded and shall be kept constant throughout the test programme. For detectors
having adjustable sensitivity, and whose adjustment range covers more than one sensitivity class, it
will be necessary to determine an appropriate aperture size for each sensitivity class of the detector.
5.1.5.4 Source stability
After determining a suitable aperture size, and before any determination of response points, the
irradiance on the optical axis of the source shall be measured using the radiometer in accordance
with A.5. This measurement shall be carried out with no modulation of the source and with the
aperture unobstructed. The measured value of irradiance shall be recorded and used as a reference
throughout the test programme to verify that the source radiance has not varied by more than 5 %.
5.1.5.5 Test procedure
The specimen shall be connected to its supply and indicating equipment and shall be allowed to
stabilize for a period of 15 min or for a time specified by the manufacturer. During this stabilization
period the specimen shall be shielded, using the shutter in accordance with A.3, from all sources of
radiation which may affect the determination of the response point.
Before commencing any measurement of response point the burner shall be allowed to reach a stable
working condition.
The distance of the specimen from the source shall be varied and at each distance the detector shall
be exposed to the source for 30 s using the shutter. The response point D is the greatest distance,
measured between the aperture and the plane of the specimen sensing element(s), at which the
detector will reliably produce an alarm response within each 30 s exposure. If the detector response is
known to be dependent on previous exposure to radiation then sufficient time shall be allowed before
each exposure to ensure that previous exposures do not substantially affect the measurement of the
response point.
For detectors having stochastic response behaviour each value of D shall come from at least six
repetitions of each measurement, D being the mean value of these repetitions. Repetitions shall
continue until an additional value changes the average value of D by less than 5 %.
5.1.6 Reduced functional tests
Where the test procedure calls for a reduced functional test, the detector shall be exposed to a source
of radiation which is sufficient to cause an alarm response from the detector. The nature of the source
used and the duration of the exposure shall be appropriate to the product in question and shall be
defined or supplied by the manufacturer.
5.1.7 Provision for tests
The following shall be provided for testing compliance with this part of EN 54:
a) for detachable detectors, eight heads and eight bases; for non-detachable detectors, eight
specimens
b) the data required in 4.2.6.2.
The specimens shall be themselves representative of the manufacturer's normal production with
regard to their construction and calibration.
prEN 54-10:2012 (E)
NOTE This implies that the mean response point of the eight specimens, found in the reproducibility test
should also represent the production mean, and that the limits specified in the reproducibility test should also be
applicable to the manufacturer's production.
5.1.8 Test schedule
The detectors shall be tested according to the test schedule given in Table 2. After the reproducibility
test (at the highest sensitivity setting) the specimen with the largest value of response point (i.e. most
sensitive) shall be numbered 1 and the least sensitive shall be number 8. The detectors in between
these shall be numbered in order of decreasing sensitivity.
