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

Introduction
Cellular plastics are widely used in products for packaging, building, housing, industry and transport, in various
applications. The burning behaviour of cellular plastics is a concern for the fire safety of these products. This
International Standard gives a method for the determination of the burning behaviour of cellular plastics using
a small flame source.
The burning behaviour of cellular plastics is influenced by the test specimen orientation (vertical or horizontal).
This method of test evaluates specimens which are oriented horizontally.
The method described is also intended as a pre-selection test for materials used for components of devices
and appliances. The final acceptance of the material would be dependent upon its use in complete equipment
that conforms with the standards applicable to such equipment.
It should be noted that the test results obtained by the test specified in this International Standard alone cannot
represent all the aspects of the fire hazard of cellular plastics in end-use conditions.

Cellular plastics β€” Determination of horizontal burning
characteristics of small specimens subjected to a small flame
1 Scope
1.1 This International Standard specifies a small-scale laboratory screening procedure for comparing the
relative burning characteristics of horizontally oriented, small cellular plastic specimens having a density less
βˆ’3
than 250 kgβ‹…m determined in accordance with ISO 845, when exposed to a small-flame ignition source.
[2]
NOTE Another International Standard exists covering flexible cellular plastic and cellular rubber: ISO 3582 .
1.2 This method of test is intended for quality assurance and limited product evaluation of cellular plastic
materials under controlled laboratory conditions, and is not intended to assess the fire behaviour of e.g. building
materials or furnishings under actual fire conditions.
1.3 The optional classification system described in Annex A is intended for the pre-selection of cellular plastic
materials for products, including the determination of the ranges of material parameters that give the same
classification (see 6.1).
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced document
(including any amendments) applies.

ISO 13943, Fire safety β€” Vocabulary
3 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO 13943 and the following apply.
3.1
afterflame time
length of time for which a material continues to flame, under specified test conditions, after the ignition source
has been removed
3.2
afterglow time
length of time for which a material continues to glow, under specified test conditions, after the ignition source
has been removed and/or extinguishment of flame
3.3
extended application of test results
process of predicting a test result, on the basis of one or more existing test results obtained by the same test,
for a product for which a property and/or the intended end-use application(s) are subject to variation
4 Significance of test
4.1 Tests conducted on a material under the conditions specified can be of considerable value when comparing
the horizontal burning characteristics of different materials, controlling manufacturing processes or assessing
any changes in formulation or treatment prior to use.
4.2 Assessment of fire hazard requires consideration of factors such as fuel contribution, intensity of burning
(rate of heat release) and products of combustion, as well as environmental factors such as intensity of source,
orientation of exposed material and ventilation conditions.
4.3 Horizontal burning characteristics, as measured by this test procedure, might be affected by factors such
as density, any anisotropy of the cellular material, its melting characteristics, its colour and its thickness.
4.4 Certain materials might shrink from the applied flame without igniting. In this event, the test results are not
valid, and additional test specimens will be required to obtain 10 valid test results. If this proves impossible due
to non-ignition of all the specimens, then this test is not suitable for these materials.
4.5 The horizontal burning characteristics of some cellular plastic materials might change with time, and tests
are therefore conducted before and after heat ageing.
5 Apparatus
5.1 Laboratory fume hood, having an inside volume of at least 0,5 m . The chamber shall permit observation
of tests in progress and shall be draught free whilst allowing normal thermal circulation of air past the test
specimen during burning. The inside surfaces of the chamber shall be of a dark colour. When a light meter,
facing towards the rear of the chamber, is positioned in place of the test specimen, the recorded light level shall
be less than 20 lux.
For safety and convenience, this enclosure (which can be completely closed) shall be fitted with an extraction
device, such as an exhaust fan, to remove products of combustion that might be toxic. The extraction device
shall be turned off during the test and turned on again immediately after the test to remove the fire effluents. A
positive closing damper might be needed.
NOTE The amount of oxygen available to support combustion is naturally important for the conduct of these flame
tests. For tests conducted by this method when burning times are protracted, chamber sizes greater than 0,5 m might be
needed to provide reproducible results.
5.2 P/PF2 laboratory burner, as specified in ISO 10093, having a barrel length of (100 Β± 10) mm and an
internal diameter of (9,5 Β± 0,3) mm. The barrel shall not be equipped with an end attachment, such as a stabilizer.
5.3 Burner wing top, having an opening of internal length (48 Β± 1) mm and internal width (1,3 Β± 0,05) mm
(see Figure 1).
To ensure the wing top opening is uniform in width, a (1,3 Β± 0,05) mm steel wire or spacer may be slid along its length.
5.4 Support gauze, approximately 215 mm long by 75 mm wide, having 13 mm of its length bent to form
a right angle at one end as shown in Figure 2. It shall consist of (6,4 Β± 0,5) mm mesh gauze constructed of
(0,85 Β± 0,10) mm diameter stainless steel or low carbon steel wire. A different support gauze is necessary for
each specimen unless means are provided to burn off any residue from a prior test.
5.5 Support-gauze holder, consisting of two laboratory ring stands with clamps adjustable to the desired
angles and heights. The support-gauze holder shall be constructed from aluminium or steel and shall satisfy the
following conditions:
β€” the long axis of the gauze is maintained to within 1Β° of the horizontal;
2 Β© ISO 2012 – All rights reserved

β€” the nearest end of the specimen is (13 Β± 1) mm above the burner wing top (see Figures 3 and 4);
β€” the space both above and below the specimen is not obstructed;
β€” a means is provided for positioning the burner in the correct location relative to the specimen, preferably
with a sliding mechanism and a stop to allow fast movement of the burner flame towards and away from
the specimen;
β€” the gauze is equidistant from the front and back, and from both sides, of the test chamber, and is
(175 Β± 25) mm above the cotton indicator base-board (see Figure 3).
5.6 Two timing devices, which can be read to within 1 s or less.
5.7 Measuring scale, graduated in millimetres, to measure the length, width and thickness of the test specimen.
5.8 Gas supply, supplying technical-grade methane gas with a purity of at least 98 % and having a heat
βˆ’3
content of (37 Β± 1) MJβ‹…m , with regulator and meter to ensure uniform gas flow.
βˆ’3
Other gas mixtures having a heat content of approximately (37 Β± 1) MJβ‹…m or propane having a heat content
βˆ’3
of (94 Β± 2) MJβ‹…m have been shown to provide similar results when using the procedure of Clause 8. In cases
of dispute, however, technical-grade methane shall be used.
5.9 Manometer and gas flow meter, calibrated for the gas used and capable of reading the values
shown in Table 1.
5.10 Cotton indicator, consisting of a pad of dry, absorbent 100 % cotton measuring approximately 150 mm
long, 75 mm wide and 6 mm thick and having a mass of approximately 0,16 g.
5.11 Desiccator, containing anhydrous calcium chloride or another drying agent which can be maintained at
(23 Β± 2) Β°C and gives a relative humidity not exceeding 20 %.
5.12 Conditioning room or chamber, capable of being maintained at (23 Β± 2) Β°C and a relative humidity
of (50 Β± 5) %.
5.13 Air-circulating oven, giving a minimum of five air-changes per hour, and capable of being maintained at
(70 Β± 2) Β°C or another agreed temperature.
5.14 Dial-gauge micrometer, for measuring the specimen thickness, with a 650 mm pressure foot exerting
a pressure of (0,175 Β± 0,035) kPa.
5.15 Cotton indicator base-board, measuring approximately 215 mm long and 75 mm wide and having a
height such that the distance between the support gauze and the top of the base-board is (175 Β± 25) mm.
The cotton indicator base-board shall be made of non-combustible board having a dry density of
βˆ’3
(850 Β± 200) kgβ‹…m . It shall not be made of metal.
