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.
ISO340 was prepared by Technical Committee ISO/TC41, Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts.
This third edition cancels and replaces the second edition (ISO 340:1988), which has been technically revised
by standardization using a single fuel source and a standardized burner having carefully controlled dimensions
within a universally available design. Greater attention has been paid to the measures to be taken in conducting
the test to ensure the safety of the personnel involved.

Introduction
At the 16th meeting of ISO/TC41/SC3 held in Nara, Japan, it was agreed that in addition to changes which were
necessary to allow the selection of test pieces from steel cord conveyor belts, this International Standard should
be revised in order to improve the reproducibility of the test method.
This revision has attempted this by:
a) standardizing the specification of the burner;
b) standardizing the orientation of the test piece with respect to the heat source;
c) measuring the heat energy impinging on the test piece.
In preparing this International Standard, reference has also been made to ISO/TR 10353:1992.

characteristics — Requirements and test method
CAUTION — This method of test is not designed to assess the fire hazard of any given product. The
results may help in the assessment of ignition hazard but should not be used in isolation as evidence
that a product or material is safe.
1Scope
This International Standard specifies a method for assessing, on a small scale, the reaction of a conveyor belt
to an ignition flame source. It is applicable to conveyor belts having a textile carcass as well as steel cord
conveyor belts.
