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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: w w w . i s o .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 41 Pulleys and belts (including veebelts),
Subcommittee SC 3, Conveyor belts.
This second edition cancels and replaces the first edition (ISO 15236-3:2007), of which it constitutes a
minor revision with the following changes:
— the references have been updated;
— Table 3 has been expanded to include belt widths from 1 800 to 3 200.

INTERNATIONAL STANDARD ISO 15236-3:2017(E)
Steel cord conveyor belts —
Part 3:
Special safety requirements for belts for use in
underground installations
1 Scope
This document specifies the performance and constructional requirements applicable to conveyor
belts for underground mining having steel cords in the longitudinal direction as reinforcement. The
requirements for design and construction apply to the design of single belts, as well as the design of
complete type series such as those covered in ISO 15236-2.
Steel cord belts in accordance with this document are intended for use underground in coal mines and
in other applications where the highest demands for safety against fire and explosion hazards have to
be complied with.
NOTE At present, the requirements can only be met by the use of compounds based on chloroprene rubber
for the covers, as well as for the bonding rubber.
