Steel cord conveyor belts - Part 3: Special safety requirements for belts for use in underground installations (ISO/DIS 15236-3:2025)

ISO 15236-3:2017 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.

Courroies transporteuses à câbles d'acier — Partie 3: Exigences de sécurité particulières aux courroies utilisées dans des installations souterraines (ISO/DIS 15236-3:2025)

ISO 15236-3:2017 spécifie les exigences relatives aux performances et à la construction applicables aux courroies transporteuses à câbles d'acier, placés dans le sens longitudinal en tant qu'armature, pour utilisation dans les mines souterraines. Les exigences de conception et de construction s'appliquent à la conception des courroies simples ainsi qu'à la conception des séries de courroies de type complet, telles que couvertes par l'ISO 15236‑2.
Les courroies à câbles d'acier conformes au présent document sont prévues pour des usages souterrains dans les houillères et autres applications où des demandes plus exigeantes de sécurité contre les risques d'incendie et d'explosion sont à respecter.
NOTE Actuellement, seule l'utilisation de mélanges à base de caoutchouc chloroprène pour les revêtements et pour la gomme de liaison permet de satisfaire aux exigences.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
