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 11925-2 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire
initiation and growth.
This third edition cancels and replaces the second edition (ISO 11925-2:2002), which has been technically
revised.
ISO 11925 consists of the following parts, under the general title Reaction to fire tests — Ignitability of
products subjected to direct impingement of flame:
1)
⎯ Part 1: Guidance on ignitability [Technical Report]
⎯ Part 2: Single-flame source test
1)
⎯ Part 3: Multi-source test
1) The main title of ISO 11925 has been changed since these parts were first published, originally referring to the
ignitability of building products only. It is intended that these parts be aligned with the new main title at their next revision.

Introduction
This fire test method has been developed to define reaction to the fire performance of products. The method
specifies a test for determining the ignitability of products by direct small-flame impingement under zero
impressed irradiance using vertically oriented test specimens.
Although the method is designed to assess ignitability, this is addressed by measuring the spread of a small
flame up the vertical surface of a specimen following application of a small (match-sized) flame to either the
surface or edge of a specimen for either 15 s or 30 s. The determination of the production of flaming droplets
depends on whether or not the filter paper placed beneath the specimen ignites.

Single-flame source test
WARNING — 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 and/or 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
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.
