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 3.
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 International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 13927 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 4,

Introduction
Fire is a complex phenomenon: its behaviour and its effects depend upon a number of interrelated factors. The
behaviour of materials and products depends upon the characteristics of the fire, the method of use of the materials
and the environment in which they are exposed (see also ISO/TR 6585 and ISO/IEC 13943).
A test such as is specified in this International Standard deals only with a simple representation of a particular
aspect of the potential fire situation, typified by a radiant heat source, and it cannot alone provide any direct
guidance on behaviour or safety in fire. A test of this type may, however, be used for comparative purposes or to
ensure the existence of a certain quality of performance (in this case heat release from a composite material or an
assembly) considered to have a bearing on fire performance generally. It would be wrong to attach any other
meaning to performance in this test.
The attention of all users of this test is drawn to the warnings that immediately precede clause 10.

Plastics — Simple heat release test using a conical radiant heater
and a thermopile detector
1 Scope
This International Standard specifies a method suitable for production control or product development purposes, for
assessing the heat release rate of essentially flat products exposed in the horizontal orientation to controlled levels
of radiant heating with an external igniter. The heat release rate is determined by use of a thermopile instead of the
more accurate oxygen consumption techniques. The time to ignition (sustained flaming) is also measured in this
test. Test specimen mass loss may optionally also be measured.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

5Principle
The heat release rate is assessed by measurement of the output of a thermopile located in a chimney situated
above a burning test specimen that is subjected to a known heat flux from a conical heater. The output (in mV) is
2
converted into heat release rate per unit area (in kW/m ) by use of a calibration graph obtained previously by
burning methane gas of known calorific value in the same apparatus. The specimen mass loss rate during the test
can also be measured by continuously recording the specimen load cell output.
6 Apparatus
6.1 General
The test apparatus shall consist essentially of the following components: a cone-shaped radiant heater, a chimney
housing a thermopile, a load cell, a specimen holder and a fume extraction system. A schematic representation of
the assembly is given in Figure 1. The individual components are described below.
NOTE Untoleranced dimensions are recommended values but should be followed closely.

6.2 Cone-shaped radiant electrical heater
The active element of the heater shall consist of an electrical heater rod, capable of delivering 5 000 W at the
operating voltage, tightly wound into the shape of a truncated cone (see Figure 2). The heater shall be encased on
the outside with a double-walled stainless-steel cone, filled between the walls with a refractory blanket of nominal
3
thickness 13 mm and nominal density 100 kg/m . The heat flux from the heater shall be maintained at a preset
level by controlling the average temperature of three type K sheathed stainless-steel thermocouples, symmetrically
disposed and in contact with, but not welded to, the heater element (see Figure 2). 1,0 mm to 1,6 mm outside
diameter sheathed (unearthed) thermocouples with an unexposed hot junction may be used. The heater shall be
2
capable of producing heat fluxes on the surface of the specimen of up to 100 kW/m . The heat flux shall be uniform
within the central 50 mm � 50 mm area of the exposed specimen surface, to within �2%.
The cone heater may be provided with a removable radiation shield to protect the specimen from heat immediately
prior to the start of the test.
6.3 Heat flux controller
The heat flux control system shall maintain the average temperature of the heater element steady to within � 2 °C.

6.4 Thermopile and housing
A circular cross-section chimney 600 mm long and 115 mm internal diameter constructed from 1-mm-thick
stainless steel shall be used to house the thermopile. This shall be fixed on top of the top-plate of the cone heater.
The axis of the chimney shall coincide with the axis of the cone heater. The thermopile shall consist of four 1,6 mm
outside diameter type K sheathed thermocouples. The thermocouples shall be housed within the chimney at a
height of 550 mm above the cone top-plate and the chimney penetration points shall be equally distributed about
the circumference of the chimney. The tips of the thermocouples shall be fixed 17 mm from the centreline of the
chimney.
6.5 Specimen holder
The specimen holder is shown in Figure 3.
The specimen holder shall have the shape of a square pan with an opening of 106 mm � 106 mm at the top, and a
depth of 25 mm. The holder shall be constructed from stainless steel with a thickness of 2,15 mm � 0,25 mm. It
shall include a handle to facilitate insertion and removal, and a mechanism to ensure central location of the
specimen under the heater and proper alignment with the weighing device. The distance between the bottom
surface of the cone heater and the top of the specimen shall be adjusted to be 25 mm except when testing
dimensionally unstable materials in which case the distance shall be adjusted to 60 mm � 1 mm. All tests shall be
conducted with the retainer frame shown in Figure 4. Details of specimen and specimen holder preparation are
givenin8.3.

6.6 Fume extraction system
The apparatus shall be used under a hood or in a fume cupboard, with adequate ventilation to remove safely
combustion products from the laboratory.
6.7 Ignition circuit
Specimen ignition shall be accomplished by a spark plug powered by a 10 kV transformer or a 10 kV spark
generator capable of continuous sparking. The spark electrodes shall have a gap of 3 mm. If a transformer is used
it shall be of a type specifically designed for spark ignition use. The transformer shall have an isolated (unearthed)
secondary to minimize interference with the data-transmission lines. The electrode length and location of the spark
plug shall be such that the spark gap is located 13 mm above the centre of the specimen in the horizontal
orientation.
6.8 Ignition timer
The timer shall be capable of recording elapsed time to the nearest second and accurate to within 1 s in 1 h.
6.9 Heat flux meter
The heat flux meter shall be of the Schmidt-Boelter (thermopile) type with a design range of up to about
2
100 kW/m . The target receiving radiation, and possibly to a small extent convection, shall be flat, circular, of
approximately 12,5 mm in diameter and coated with a durable matt-black finish. The target shall be water-cooled
but care shall be taken that this does not cause water condensation on the target surface of the meter.
Radiation shall not pass through any window before reaching the target. The instrument shall be robust, simple to
set up and use, and stable in calibration. The instr
