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 1716 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 1716:2002), which has been technically
revised.

Reaction to fire tests for products — Determination of the gross
heat of combustion (calorific value)
WARNING — The attention of all persons concerned with managing and carrying out this test is drawn
to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful
gases may be evolved during the test. Operational hazards may also arise during the testing of
specimens, such as the possibility of an explosion, and during the disposal of test residues.
WARNING — An assessment of all the potential hazards and risks to health shou
