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.

INTERNATIONAL STANDARD ISO 1182:2010(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.
