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 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 rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1182 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation
and growth.
This fifth edition cancels and replaces the fourth edition (ISO 1182:2002), which has been technically
revised.

Introduction
This fire test has been developed for use by those responsible for the selection of construction products
which, whilst not completely inert, produce only a very limited amount of heat and flame when exposed
to temperatures of approximately 750 °C.
The limitation of the field of application to testing homogeneous products and substantial components
of non-homogeneous products was introduced because of problems in defining specifications for the
specimens. The design of the specimen of non-homogeneous products strongly influences the test
results, which is the reason non-homogeneous products cannot be tested to this International Standard.

DRAFT INTERNATIONAL STANDARD ISO/DIS 1182:2019(E)
Reaction to fire tests for products — Non-combustibility test
SAFETY PRECAUTIONS — The attention of all persons concerned with managing and carrying
out this test is drawn to the fact that fire testing can be hazardous and that there is a possibility
that toxic, harmful smoke and gases can be evolved during the test. Operational hazards can
also arise during the testing of specimens and the disposal of test residues.
An assessment of all potential hazards and risks to health should be made and safety precautions
should be identified and provided. Written safety instructions should be issued. Appropriate
training should be given to relevant personnel. Laboratory personnel should ensure that they
follow written safety instructions at all times.
1 Scope
This International Standard specifies a method of test for determining the non-combustibility
performance, under specified conditions, of homogeneous products and substantial components of
non-homogeneous products.
Information on the precision of the test method is given in Annex A.

rod moving freely within a vertical guide fitted to the side of the furnace.
The specimen holder for loose fill materials shall be cylindrical and of the same outer dimensions as the

inserted in this plane to indicate the dimensions, i.e. the distances to the furnace wall and the specimen
surface, but are not located in this plane. The position of the furnace thermocouples in relation to each
other and to the surface thermocouple can be seen in the lower drawing of Figure 2. The correct position

5.2.2 The layers shall occupy a horizontal position in the specimen holder and shall be held together
firmly, without significant compression, by means of two fine steel wires, of maximum diameter 0,5 mm,
to prevent air gaps between layers. The specimens of loose fill materials shall be representative in

5.2.3 Where adhesives or other liquid-applied products are used in thicknesses where they can be
classified as substantial components, the following procedure shall be used.
5.2.3.1 An initial single solid test specimen shall be cast in a plastic tube of the correct or appropriate
diameter. This initial specimen shall be tested.
NOTE Some corrections for shrinkage can be required to give the required test specimen diameter (trial and
error determines this).
5.2.3.2 If this initial test specimen behaves normally in the test, the remaining test specimens shall be
made by this method and tested.
5.2.3.3 If the initial test specimen shows abnormal behaviour (such as spalling or explosive releases
due to air pockets), the method of specimen preparation, as described in 5.2.3.4, shall be applied.
5.2.3.4 If the method of casting solid test specimens is not applicable, all five test specimens shall be
built up from discs cut from sheets of the liquid-based adhesive (or other liquid applied product) cast at
the maximum expected in-use thickness.
5.2.3.5 When the test specimens of this type are prepared with a hole on the central axis for measuring
the temperature inside the test specimen (see Annex C), flammable gas can develop inside the hole
and result in flaming. When testing liquid-based adhesives or other liquid-applied products, the tests
in accordance with this International Standard should be performed without any additional optional
