Standard test method for assessing the ignition propensity of cigarettes (ISO 12863:2022)

This document specifies a test method for testing the capability of a cigarette, positioned on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus potentially cause ignition of bedding or upholstered furniture. This document is only applicable to factory-made cigarettes that burn along the length of a tobacco column.
This is a performance-based document; it does not prescribe any design features of the cigarette that can lead to improved or degraded performance in the test method. The output of this method has been correlated with the potential for cigarettes to ignite upholstered furniture.

Normprüfverfahren zur Beurteilung der Zündneigung von Zigaretten (ISO 12863:2022)

Dieses Dokument legt ein Prüfverfahren für die Prüfung der Fähigkeit einer Zigarette fest, auf einem von drei Normsubstraten entweder zu verlöschen oder ausreichend Wärme zu entwickeln, um den Abbrand fort¬zusetzen und dadurch möglicherweise die Entzündung von Bettwäsche oder gepolsterten Möbeln hervor¬zurufen. Dieses Dokument gilt nur für fabrikmäßig hergestellte Zigaretten, die entlang der Länge eines Tabak¬strangs abbrennen.
Es handelt sich um ein leistungsbezogenes Dokument, das keine Gestaltungscharakteristika der Zigarette vorschreibt, die zu einer Verbesserung oder Verschlechterung der Testergebnisse im Prüfverfahren führen können. Das Ergebnis dieses Verfahrens ist mit der Neigung von Zigaretten, Polstermöbel zu entzünden, korreliert worden.
WARNUNG — Dieses Dokument ist mit dem Umgang mit brennbaren Werkstoffen verbunden, die einer Zündquelle ausgesetzt sind. Die brennenden Werkstoffe emittieren giftige Verbrennungs¬produkte. Der Anwender muss geeignete Sicherheitsmaßnahmen treffen, um Verbrennungen und das Einatmen von Verbrennungsprodukten zu verhindern. Der Anwender muss sicherstellen, dass alle Flammen erloschen sind, bevor die Prüfmaterialien entsorgt werden.

Méthode d'essai normalisée pour évaluer le potentiel incendiaire des cigarettes (ISO 12863:2022)

Le présent document spécifie une méthode d’essai pour évaluer la capacité d’une cigarette, positionnée sur un des trois substrats normalisés, à s’éteindre ou à générer suffisamment de chaleur pour continuer à se consumer et, par conséquent, à potentiellement mettre le feu à la literie ou aux meubles rembourrés. Le présent document s’applique aux cigarettes manufacturées se consumant sur la longueur d’une colonne de tabac.
Il s’agit d’un document fondé sur les performances; il ne décrit pas les caractéristiques de conception de la cigarette susceptibles d’aboutir à des performances supérieures ou inférieures selon la méthode d’essai. Le résultat de cette méthode a été corrélé avec le potentiel des cigarettes à incendier les meubles rembourrés.

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.

This document is based, with permission from ASTM International, on ASTM International E2187,

Standard Test Method for Measuring the Ignition Strength of Cigarettes, copyright ASTM International.

Standard test method for assessing the ignition propensity
of cigarettes

WARNING — This document involves the use of combustible materials that are exposed to

ignition sources. The burning materials emit toxic combustion products. The user shall take

proper precautions to avoid thermal injury and inhalation of combustion products. The user

shall ensure that all burning has ceased before safely discarding test materials.

1 Scope

This document specifies a test method for testing the capability of a cigarette, positioned on one of

three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus

potentially cause ignition of bedding or upholstered furniture. This document is only applicable to

factory-made cigarettes that burn along the length of a tobacco column.

This is a performance-based document; it does not prescribe any design features of the cigarette that

can lead to improved or degraded performance in the test method. The output of this method has been

correlated with the potential for cigarettes to ignite upholstered furniture.

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 2022 – All rights reserved
---------------------- Page: 14 ----------------------
SIST EN ISO 12863:2022
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

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

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

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.

The International Organization for Standardization (ISO) draw attention to the fact that it is claimed

that compliance with this document may involve the use of a patent.

ISO take no position concerning the evidence, validity and scope of this patent right.

The holder of this patent right has assured ISO that he/she is willing to negotiate licences under

reasonable and non-discriminatory terms and conditions with applicants throughout the world. In

this respect, the statement of the holder of this patent right is registered with ISO. Information may be

obtained from the patent database available at www .iso .org/ patents.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights other than those in the patent database. ISO shall not be held responsible for identifying

any or all such patent rights.

DRAFT INTERNATIONAL STANDARD ISO/DIS 12863:2021(E)
Standard test method for assessing the ignition propensity
of cigarettes

WARNING — This International Standard involves the use of combustible materials that are

exposed to ignition sources. The burning materials emit toxic combustion products. The user

shall take proper precautions to avoid thermal injury and inhalation of combustion products.

The user shall ensure that all burning has ceased before safely discarding test materials.

1 Scope

This International Standard provides a standard assessment of the capability of a cigarette, positioned

on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning,

and thus potentially cause ignition of bedding or upholstered furniture. This International Standard

is applicable to factory-made cigarettes that burn along the length of a tobacco column. This is a

performance-based standard; it does not prescribe any design features of the cigarette that might

lead to improved or degraded performance in the test method. The output of this method has been

correlated with the potential for cigarettes to ignite upholstered furniture.

3.5
test
set of 40 determinations
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 nominally

the length of the tobacco column, as defined in this International Standard. Forty determinations

(comprising a test) are 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 description

An apparatus consists of a holder for the filter paper substrate, a metal rim to compress the layers

of filter paper, a clear enclosure to protect the test specimens from air currents, and associated

accessories, as defined in this clause. The materials of construction shall meet occupational health and

safety requirements. The apparatus shall be placed under a fume hood to minimize the exposure of

personnel to combustion products. Technical drawings of the test chamber are provided in Annex A.

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.

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 needed

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 convenient 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 are provided in Annex A.

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 are provided in Annex A.

5.5 Metal rim

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 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 are provided in Annex A. 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 below 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 nominally 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.
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 might 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

A 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 International Standard or

ASTM E2187 .

NOTE The frequency of performance verification is determined by the quality control program implemented

by the laboratory and also determined by any requirements imposed by e.g. 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
