Overview
EN ISO 12863:2022 (ISO 12863:2022) is the CEN-adopted international test method for assessing the ignition propensity of cigarettes. The standard defines a laboratory procedure to determine whether a factory-made cigarette will extinguish or generate enough heat to continue burning and potentially ignite bedding or upholstered furniture. It is a performance-based method that does not prescribe cigarette design features; instead it measures outcomes that have been correlated with real-world ignition risk.
Key topics and technical requirements
- Scope and applicability: Applicable to factory-made cigarettes that burn along the length of a tobacco column. Focus is on ignition propensity related to soft furnishings.
- General principle: A cigarette is positioned on one of three standard substrates and observed to determine whether it extinguishes or continues to burn and transfer sufficient heat to the substrate.
- Apparatus and components: Test chamber and conditioning facilities, substrate holder, metal rim, cigarette holder, cigarette ignition system, exhaust hood and environmental controls are specified to ensure repeatable results.
- Conditioning and handling: Procedures for cigarette sampling, handling, storage and conditioning of both cigarettes and filter-paper substrates are included to control test variability.
- Verification and calibration: Requirements for verification of test equipment, chamber leakage checks, atmosphere stability, and sensor performance to maintain test integrity.
- Test procedure and reporting: Stepwise test conduct, recording requirements and standardized test reporting are provided to ensure consistent interpretation and traceability.
- Annexes: Normative and informative annexes cover technical drawings, substrate selection, substrate physical parameters (Annex G), repeatability and reproducibility, ignition susceptibility of substrates, and use of semi-/fully-automated testing systems.
Applications and who uses it
- Cigarette manufacturers - for product development, quality control and assessing reduced-ignition-propensity designs without being told how to design them.
- Independent testing laboratories - to provide accredited ignition-propensity test results for compliance and certification.
- Regulators and standards bodies - to define performance requirements and evaluate product conformity related to fire safety of consumer products.
- Fire safety researchers and insurers - for studies linking cigarette ignition behavior to furniture and bedding fire risk and for risk assessment.
- Public health and consumer safety organizations - for evaluating interventions that reduce fire-caused injuries and fatalities.
Related standards and provenance
- EN ISO 12863:2022 supersedes the 2010 edition and incorporates prior amendments. It is based with permission on ASTM E2187 (Standard Test Method for Measuring the Ignition Strength of Cigarettes). Annex G adds guidance on physical parameters of filter paper substrates used for the determination of ignition propensity.
Keywords: EN ISO 12863:2022, ISO 12863:2022, ignition propensity of cigarettes, cigarette ignition test, reduced ignition propensity, upholstered furniture fire safety, cigarette burn test.

Introduction
A very common initiating event in a fatal fire is the dropping of a cigarette onto a bed or piece of
upholstered furniture. The burning cigarette heats the furnishing materials to the point where
smouldering combustion begins, perhaps followed by a transition to flaming combustion. Since limiting
the frequency of ignitions is a principal approach to reducing fire loss, it is desirable to establish a test
method for the propensity of a cigarette to ignite soft furnishings.

4 General principle
This test method measures the probability that a cigarette, placed on a heat absorbing substrate, will
generate sufficient heat to maintain burning of the tobacco column and potentially initiate a fire. Each
determination consists of placing a lit cigarette on one of three standard substrates (3, 10 or 15 layers
of filter paper). Observation is made of whether or not the cigarette continues to burn the length of
the tobacco column determined, as defined in this document. A test (comprising 40 determinations)
is performed to obtain the relative probability that the cigarette will continue burning despite heat
abstraction by the substrate.
For use of semi-automated/fully automated systems to perform the test, see Annex F.
5 Apparatus
5.1 General
The usual laboratory apparatus and, in particular, the following shall be used.
5.1.1 Holder, for the filter paper substrate.
5.1.2 Metal rim to compress the layers of filter paper.
5.1.3 Clear enclosure, to protect the test specimens from air currents.
5.1.4 Associated accessories, as defined in this subclause.
The materials of construction shall meet occupational health and safety requirements.
The test apparatus shall be placed under a fume hood to minimize the exposure of personnel to
combustion products. Technical drawings of the test chamber given in Annex A shall be followed.
5.2 Test and conditioning environment
5.2.1 General
Cigarettes and filter paper shall be conditioned in one of the two ways described in 5.2.2 and 5.2.3.
ISO 12863:2022(E)
5.2.2 Conditioning room
An environmental conditioning room shall be maintained which provides an area adequate for
conditioning both cigarettes and filter paper specimens. This room shall be capable of maintaining a
relative humidity of (55 ± 5) % and a temperature of (23 ± 3) °C and shall be continuously monitored. The
room in which the tests are conducted, which may also be the conditioning room, shall be maintained
within the same temperature and relative humidity ranges.
NOTE These conditioning requirements are consistent with those used for fire safety testing. Other types of
testing can require different conditioning requirements.
5.2.3 Conditioning box
Alternatively, cigarettes and filter paper shall be stored in a box of sufficient size to hold the required
quantities of filter paper and cigarettes. The interior of the box shall be maintained at the same
temperature and relative humidity conditions as in 5.2.2 and shall be continuously monitored. A tray
containing a saturated solution of sodium bromide (NaBr) in water will provide the appropriate relative
humidity when the box temperature is as prescribed. The box shall be located conveniently in relation
to the test chamber such that test materials shall not be exposed to a non-conditioned environment for
more than 5 min between their removal from the box and the beginning of a determination.
5.3 Test chamber
A rectangular test chamber with a chimney that can be placed under an exhaust hood (5.8) shall be
constructed of clear, rigid material that allows observation of the entire determination.
NOTE Clear polymethylmethacrylate (PMMA) has been found suitable for this purpose.
The inside dimensions of the test chamber shall be: height (340 ± 25) mm, width (292 ± 6) mm and
depth (394 ± 6) mm. The full front panel of the chamber shall be hinged, with a latch to effect positive
closure. The top of the chamber shall have a flattop cylindrical chimney of height (165 ± 13) mm and
inside diameter (152 ± 6) mm. The chimney shall be centred on the chamber top and sealed to the
chamber top panel. A sheet of rigid material shall be used to cover the chimney when required in the
test procedure (Clause 9). The chamber shall be supported on four feet, located near each corner, each
approximately 15 mm in height. Technical drawings of the test chamber given in Annex A shall be
followed.
5.4 Substrate holder
A cylindrical support for the layers of circular filter paper shall be made of rigid material.
NOTE Clear polymethylmethacrylate (PMMA) has been found suitable for this purpose.
The outer diameter of the substrate holder shall be (165 ± 1) mm, the inner diameter shall be
(127 ± 1) mm and the height shall be (50 ± 1) mm. A recess in the top, (10 ± 2,5) mm deep, shall
expand the inner diameter to (152 ± 1) mm. Three or four legs shall raise the bottom of the holder
approximately (20 ± 1) mm above the chamber floor. Technical drawings of the holder given in Annex A
shall be followed.
5.5 Metal rim
−3
A circular metal rim, made of brass with a density of (8 550 ± 150) kg·m or other, equally dense
material shall be used to hold the sheets of filter paper flat against each other. The outside diameter
of the rim shall be (150 ± 1) mm and shall not exceed the inner diameter of the recess in the substrate
holder. The inner diameter shall be (130 ± 2) mm. The thickness shall be (6,4 ± 1) mm. The mass
shall be between 235 g and 295 g. The rim surfaces shall be flat and smooth. A pair of parallel metal
pins, each approximately 1 mm in diameter and whose inner distance is (8,1 ± 0,05) mm apart, shall
be located (3,2 ± 0,05) mm from the bottom of the rim and shall protrude (17 ± 1) mm toward the
centre of the rim. The pins shall be spaced to prevent the non-ignited end of a conventional 25 mm
ISO 12863:2022(E)
circumference cigarette from rolling, but without pressuring the cigarette. If cigarettes of significantly
different diameter are to be tested, other pairs of pins, appropriately spaced, shall be inserted into the
rim. Technical drawings of the rim given in Annex A shall be followed. Information on the placement of
additional pins is provided in Annex B.
5.6 Cigarette holder
A holder shall be used to support the lit cigarette in a horizontal position in the test chamber prior to
placement of the cigarette onto the substrate. The holder shall not clamp the cigarette or stress it in any
other manner, nor shall it contact the cigarette within 30 mm of its lit end.
5.7 Cigarette ignition system
A system consisting of an air draw component and an ignition source shall be used to ignite the test
cigarettes. The cigarette shall be supported in a horizontal position. A butane gas lighter capable of
producing a stable, luminous flame or a hot element igniter shall be used for lighting the cigarette. The
air flow and the draw time through the cigarette shall be sufficient to light the cigarette and continue
the combustion to within ±1 mm of the mark 5 mm from the original tip of the cigarette.
5.8 Exhaust hood
A chemical or canopy hood shall be used for removing combustion products from the test room. Air
flow through the hood shall be sufficient to remove cigarette and substrate combustion products while
not being high enough to influence the combustion processes in the test chamber(s) (see 6.3).
6 Verification of test equipment
6.1 Frequency of verification
Verification of equipment shall be carried out as noted in the following subclauses and at any time
when equipment or test conditions indicate that evaluation and re-calibration are necessary. The time
intervals for verifications stated in this method shall be considered to be the minimum.
6.2 Examination for chamber leakage
The test chamber shall be checked before use to minimize air leakage so that the smoke plume from
a cigarette rises undisturbed during testing. Door seals shall be checked visually to ensure that they
are closed flush against the chamber's side wall and the latching device secures the door tightly. All
construction seams shall be inspected to ensure they are airtight and no cracks shall be visible on any
surface of the test chamber.
6.3 Stability of chamber atmosphere
The stability of the air inside the test chamber shall be determined by placing a lit cigarette in the test
position on three or more layers of filter paper, then closing the chamber door. Air movement in the
chamber shall be observed to ensure that smoke being emitted by the cigarette is rising vertically and
is not showing turbulence within 150 mm above the lit end of the cigarette. This operation shall be
conducted prior to use on each day of testing.
If turbulence is noted, then:
a) the test chamber shall be checked for leaks;
b) the test chamber locations shall be evaluated for excess air flow in the laboratory;
c) the air flow of the exhaust system shall be evaluated as the source of the disturbance.
All sources of the turbulence shall be corrected prior to starting testing.
ISO 12863:2022(E)
6.4 Humidity and temperature sensors
It shall be assured that the humidity and temperature sensors used to record environmental conditions
in the test room and the conditioning room or conditioning box are operating with the required
accuracy. Temperature and humidity shall be validated by using sensors calibrated with a traceable
standard. This shall be performed at least weekly unless otherwise prescribed.
NOTE An inaccurate sensor can lead to the rejection of all test data since the last verification of accuracy.
One way to lessen this possibility is the use of two independent sensors for temperature and two independent
sensors for relative humidity.
6.5 Test performance verification
The laboratory shall verify the performance of the total test system and operator, using a monitor test
piece (cigarette) whose ignition propensity has been established using this document or ASTM E2187.
1)
NOTE 1 Standard Reference Material 1082 , a standardized cigarette that can be obtained from the (U.S.)
National Institute of Standards and Technology, has been widely used for this purpose. Information regarding
SRM 1082 can be found at: https:// www -s .nist .gov/ srmors/ view _detail .cfm ?srm = 1082.
NOTE 2 The frequency of performance verification is determined by the quality control programme
implemented by the laboratory and also determined by any requirements imposed by, for example, clients and/
or regulatory authorities. When the verification is sufficiently frequent and the analytical process is stable,
all the test results between two valid verifications are assumed to be valid. By contrast, test results obtained
during a period that begins with a valid check result and ends with a non-valid check result are regarded as non-
valid, pending the outcome of further investigation. Thus, the frequency of verification is balanced between the
magnitude of potentially lost data and the resources expended for verification.
7 Test specimens and standard substrate assemblies
7.1 Handling
Cigarette test specimens and filter paper substrates are sensitive to contamination and shall be handled
in such a way as to avoid any contamination. Test cigarettes shall be handled only by the last nominal
25 mm of the end of the cigarette that is not to be lit. The circular sheets of filter paper shall not be
handled in the vicinity where the cigarette will contact the paper during a determination. In all cases,
the materials shall be handled with dry hands only.
NOTE The use of clean, dry, non-powdered surgical gloves can mitigate incidental contamination of the test
materials while maintaining operator dexterity.
7.2 Cigarettes
7.2.1 Cigarette sampling
For each type of cigarette to be tested, the test specimens shall be representative of a population of
cigarettes manufactured for sale. The sampling procedure shall be consistent with one of the methods
for sampling, i.e. at the point of sale or at the factory, described in ISO 8243.
7.2.2 Care in handling and storage
Cigarette test specimens shall be protected from physical or environmental damage while in handling
and storage. It is important that the specimens are not crushed or deformed in any manner. Measures
shall be taken to ensure that the specimens are not contaminated while in storage and they shall be

protected from degradation by insects. If the specimens are to be stored by the testing laboratory for
more than one week, they shall be placed in a freezer at 0 °C to −20 °C reserved for the sole protection of
cigarette specimens to minimize the risk of contamination, deformation or degradation.
7.2.3 Markings
Prior to testing, cigarette test specimens shall be marked, using a soft graphite pencil or other marking
device, (5 ± 1) mm and (15 ± 1) mm from the end of the cigarette that will be lit. These marks are used
to establish the start (see 9.6) and completion (see 9.11) of a uniform pre-burn period, respectively.
Therefore, the marks shall be placed such that they are visible during the test procedure, such as on the
cigarette paper seam. Neither the marking of the cigarette nor the mark itself shall distort the cigarette
or puncture the cigarette paper.
7.3 Filter paper
7.3.1 General description
The substrates shall consist of nominal 150 mm diameter circles cellulosic filter paper as specified in
Table G.1. Substrates are formed by placing multiple layers of filter paper into the holder assembly, then
placing the metal rim on top to ensure good contact between the layers.
2)
NOTE The outcome of a determination is sensitive to the properties of the substrate. Whatman No. 2 is the
filter paper with which virtually all prior cigarette ignition propensity data have been developed. It was used as
the reference substrate in the previous editions of this document.
7.3.2 Paper mass requirements
7.3.2.1 Conditioned filter paper
For paper from a manufacturer's batch to be used in testing, the mean mass and standard deviation of
five sets of 15 sheets of the conditioned filter paper shall be determined by weighing five samples of
15 sheets, each sample being from a different box from the manufacturer's batch. The mean mass of the
five samples shall be (26,1 ± 0,5) g. The standard deviation of the five sample masses shall be no more
than 0,3 g.
7.3.2.2 Dried filter paper
For paper from a manufacturer's batch to be used in testing, the mean mass and standard deviation of
five sets of 15 sheets of the dried filter paper shall be determined by weighing five samples of 15 sheets,
each sample being from a different box from the manufacturer's batch. Each set of 15 sheets shall have
been stored at (60 ± 2) °C for at least 16 h, placed in a sealed plastic bag upon removal from the oven,
cooled to (23 ± 3) °C, and weighed within 3 min of opening the bag. The mean mass of the five samples
shall be (24,7 ± 0,5) g. The standard deviation of the five sample masses shall be no more than 0,3 g.
7.3.3 Paper orientation
Determinations shall be conducted with the rough sides of all paper sheets facing up.
8 Conditioning
8.1 Cigarettes
Cigarettes shall be conditioned at the relative humidity and temperature conditions in 5.2.2 for at
least 24 h prior to testing. The cigarettes shall be placed in a clean, open container, with the number of

cigarettes being sufficiently small as to enable free air access to the specimens, for example, a maximum
of 20 cigarettes in a 250 ml polyethylene or glass beaker.
8.2 Filter paper
Boxes of filter paper shall be conditioned at the relative humidity and temperature conditions in 5.2.2
for at least one week prior to testing. The top of each 100-sheet box of filter paper shall be removed prior
to being placed in the conditioning room or box. The top opening of the box shall not be obstructed. The
paper sheets need not be removed from the box. Alternatively, sets of no more than 15 sheets of filter
paper shall be conditioned at a relative humidity of (55 ± 5) % and a temperature of (23 ± 3) °C for at
least 8 h prior to testing. These filter paper sets shall have been removed from the box and shall be
stored with at least 1 mm spacing between the sets to enable free access of air to the specimens.
9 Test procedure
9.1 Turn on the exhaust system prior to beginning testing to ensure stable removal of test combustion
products.
9.2 Ensure that the substrate holder is in the test chamber at the geometric centre of its bottom.
Cover the chimney on the test chamber.
9.3 If the relative humidity and temperature in the test room cannot be maintained within the
specified ranges, the filter papers and cigarettes shall be sealed in plastic bags in the conditioning room
and transported. Care shall be taken to ensure that test materials are protected from physical damage
during transport and prior to use.
9.4 Immediately before testing, place the required number of filter papers in the appropriate
orientation on the substrate holder and place the metal rim on top. Discard filter papers that will not lie
flat. Ensure that the rough sides of all filter papers are facing up.
If the number of filter papers in the substrate has been pre-determined as one of the three substrates
described in Clause 4, testing shall be conducted with the required substrate. If the number of filter
papers has not been pre-decided, select the number of filter papers using the procedure in Annex C.
9.5 Place the cigarette holder on the floor of the chamber, just forward of the centre of the substrate
holder.
9.6 Without delay, remove a cigarette from the conditioned space. Insert the unmarked end of the
cigarette into the cigarette ignition system and hold it in a horizontal position. Turn on the air draw.
Hold the ignition flame or hot wire coil just in front of the marked end of the cigarette for as long as
is necessary to achieve uniform ignition without passing the 5 mm mark. During the ignition process,
the cigarette shall be rotated as needed to obtain an approximately symmetrical burn, avoiding
deformation of the cigarette during the process.
If the operator is performing concurrent determinations in multiple test chambers, the operator shall
not light a third cigarette until each of the first two cigarettes has been placed on its respective set of
filter papers. No more than two cigarettes shall be in the pre-burn stage at any time.
This provision need not be followed by an individual test operator if that operator has demonstrated
that lifting the restriction does not introduce error that significantly changes either the measured
ignition strength or the uncertainty of that measurement. This determination shall be the responsibility
of the testing laboratory.
9.7 Holding the cigarette vertically, lit end up, transport the cigarette to the test chamber.
ISO 12863:2022(E)
NOTE It has been found that holding a 600 ml beaker over the lit cigarette is helpful in mitigating the
likelihood of a foreign object or room air current impacting the cigarette during transport and thus leading to the
need to terminate the determination.
9.8 Place the lit cigarette, in a horizontal position with the cigarette paper seam up, in the cigarette
holder.
9.9 Simultaneously close the door and remove the chimney cover.
9.10 If the cigarette self-extinguishes while in the cigarette holder, terminate the determination and
record the results as a self-extinguishment, noting that this occurred in the holder. This attempt shall
count as a valid determination. The test operator shall be permitted to re-use this set of sheets of filter
paper. However, if the room is not at the standard conditioning temperature and humidity (see 5.2.2),
the paper shall be reconditioned in a constant humidity box (see 5.2.3).
9.11 When the cigarette has burned to the 15 mm mark, simultaneously cover the chimney and open
the chamber door, gently remove the cigarette from the holder and move the holder to the front corner
of the test chamber and ensure that the holder is located where it will not interfere with the remainder
of the test operation.
9.12 Gently lay the cigarette with the ash still attached onto the top of the filter papers so that the non-
ignited end is placed between the appropriately sized cigarette anti-roll parallel metal pins (according
to 5.6 and Annex A). The mouth end shall be in contact with the metal rim. The cigarette paper seam
shall be turned up. Do not drop the cigarette onto the filter papers and do not press the lit end into
the papers. If the ash falls off during any part of the transport or positioning process, terminate the
determination and begin again; do not count the attempt.
9.13 Without delay, simultaneously remove the chimney cover and gently close the door.
9.14 Observe the burning cigarette. The smoke plume near the cigarette shall remain undisturbed. If
it does not, the chamber and exhaust system shall be re-checked (see 6.2). If the chamber and exhaust
system are in accordance with
