Conveyor belts - Specification for rubber- or plastics-covered conveyor belts of textile construction for underground mining (ISO 22721:2007)
ISO 22721:2007 specifies requirements for rubber- or plastics-covered conveyor belting of textile construction for underground mining on flat or troughed idlers. It is not applicable to light conveyor belts as described in ISO 21183‑1. ISO 22721:2007 does not include requirements for plastics covers.
Fördergurte - Anforderungen an Textilfördergurte mit Gummi- oder Kunststoff-Deckplatten für Anwendungen unter Tage (ISO 22721:2007)
Diese Internationale Norm legt Anforderungen an Textilfördergurte mit Gummi- oder Kunststoff-Deckplatten für Anwendungen unter Tage auf geraden oder gemuldeten Rollen fest. Sie gilt nicht für leichte Fördergurte nach ISO 21183-1.
Diese Internationale Norm enthält keine Anforderungen an Kunststoffabdeckungen. Diese müssen zwischen dem Hersteller und dem Käufer unter Berücksichtigung der Art des zu verwendenden Kunststoffs vereinbart werden.
Punkte, die nicht Anforderungen dieser Internationalen Norm darstellen, die aber zwischen Hersteller und Käufer vereinbart werden sollten, sind im informativen Anhang A enthalten.
In Anhang B sind Einzelheiten enthalten, die vom Käufer der Förderanlage zusammen mit einer Anfrage zur Verfügung gestellt werden sollten.
Die Fähigkeit eines Gurtes richtungsstabil zu laufen, kann nicht beurteilt werden, solange der Gurt nicht eingebaut ist. Diesbezügliche Anforderungen sind deshalb nicht Teil des Anwendungsbereiches dieser Internationalen Norm, allerdings werden in Anhang C Empfehlungen für die seitliche Drift gegeben.

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 22721 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 41, Pulleys and belts (including veebelts), Subcommittee SC 3, Conveyor belts,
in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

INTERNATIONAL STANDARD ISO 22721:2007(E)
Conveyor belts — Specification for rubber- or plastics-covered
conveyor belts of textile construction for underground mining
WARNING — Users of this International Standard should be aware that relevant electrical and
flammability safety requirements are given in EN 14973, which specifies safety classes for belts
intended for use in underground installations. When contracts are entered into for the purchase of
belts for use in underground mining, compliance with both this International Standard and the
relevant class in EN 14973 should be specified. Attention is drawn to local regulations for safety which
might be in place where the belts are to be used.
1 Scope
This International Standard specifies requirements for rubber- or plastics-covered conveyor belting of textile
construction for underground mining on flat or troughed idlers. It is not applicable to light conveyor belts as
described in ISO 21183-1.
This International Standard does not include requirements for plastics covers. These will need to be agreed
upon by the manufacturer and purchaser, taking into account the type of plastics to be used.
Related items that are not requirements of this International Standard, but which it is recommended be agreed
upon by the manufacturer and purchaser, are included in Annex A.
Details recommended to be supplied by the purchaser of belting with an enquiry are given in Annex B.
The ability of a belt to run straight cannot be assessed until the belt is installed. Requirements for this are,
therefore, outside the scope of this International Standard; nevertheless, recommendations for lateral drift are
given in Annex C.
