Conveyor belts - Specification for rubber- or plastics-covered conveyor belts of textile construction for underground mining (ISO 22721:2023)
This document specifies requirements for rubber- or plastics-covered conveyor belting of textile construction for use in underground mines and disposed on flat or troughed idlers. It is not applicable to light conveyor belts as described in ISO 21183-1.
This document does not include requirements for plastics covers. These are 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 document, 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 document; nevertheless, recommendations for lateral drift are given in Annex C.
Attention is drawn to local regulations for safety which might be in place where the belts are to be used.
Fördergurte - Anforderungen an Textilfördergurte mit Gummi- oder Kunststoff-Deckplatten für Anwendungen unter Tage (ISO 22721:2023)
Dieses Dokument legt Anforderungen an Textilfördergurte mit Gummi- oder Kunststoff-Deckplatten für Anwendungen unter Tage auf geraden oder gemuldeten Rollen fest. Es ist nicht anwendbar für leichte Fördergurte nach ISO 21183 1.
Dieses Dokument enthält keine Anforderungen an Kunststoffabdeckungen. Diese werden zwischen dem Hersteller und dem Käufer unter Berücksichtigung der Art des zu verwendenden Kunststoffs vereinbart.
Verwandte Punkte, die keine Anforderungen dieses Dokuments darstellen, die aber zwischen Hersteller und Käufer vereinbart werden sollten, sind in Anhang A enthalten.
In Anhang B sind Einzelheiten enthalten, die der Käufer der Gurte zusammen mit einer Anfrage angeben sollte.
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 dieses Dokuments, sind jedoch in Anhang C als Empfehlungen für die seitliche Drift aufgeführt.
Es wird auf lokale Sicherheitsvorschriften hingewiesen, die dort vorhanden sind, wo die Gurte verwendet werden.
Courroies transporteuses - Spécification pour courroies transporteuses à structure textile recouvertes de caoutchouc ou de plastique, pour utilisation dans les mines souterraines (ISO 22721:2023)
Le présent document spécifie les exigences relatives aux courroies transporteuses à structure textile recouvertes de caoutchouc ou de plastique pour utilisation dans les mines souterraines et disposées sur rouleaux plats ou en auge. Il ne s'applique pas aux courroies transporteuses légères décrites dans l'ISO 21183-1.
Le présent document n'inclut pas les exigences relatives aux revêtements plastiques. Ceux-ci font l'objet d'un accord entre le fabricant et l'acheteur, en tenant compte du type de plastique à utiliser.
Les points associés qui ne sont pas des exigences du présent document, mais dont il est recommandé qu'ils soient convenus par le fabricant et l'acheteur, sont inclus dans l'Annexe A.
Les renseignements qu'il est recommandé à l'acheteur d'une courroie de fournir avec une commande sont donnés à l'Annexe B.
La capacité d'une courroie à avoir une course rectiligne ne peut être évaluée qu'une fois la courroie installée. Les exigences en la matière sont, par conséquent, hors du domaine d'application du présent document; néanmoins, des recommandations concernant la dérive latérale sont donnés à l'Annexe C.
L'attention est attirée sur les réglementations locales en matière de sécurité qui peuvent exister là où les courroies doivent être utilisées.
Naprave za kontinuirni transport - Trakovi tračnih transportejev - Zahteve za tračne transportne trakove z gumeno ali plastično oblogo ter tekstilnim vložkom za podzemno rudarstvo (ISO 22721:2023)
Ta dokument določa zahteve za tračne transportne trakove z gumeno ali plastično oblogo ter tekstilnim vložkom za uporabo v podzemnem rudarstvu na ravnih ali koritastih tleh. Ne uporablja se za lahke trakove tračnih transporterjev iz standarda ISO 21183-1. Dokument ne vključuje zahtev za plastične obloge. O tem se dogovorita proizvajalec in kupec ob upoštevanju vrste plastike, ki bo uporabljena. Povezani elementi, ki niso zajeti v zahtevah tega dokumenta, vendar je priporočljivo, da se o njih dogovorita proizvajalec in kupec, so zajeti v dodatku A. Podrobnosti, za katere je priporočljivo, da jih kupec trakov priloži poizvedbi, so podane v dodatku B. Zmožnost traku, da deluje v ravni liniji, je mogoče oceniti šele po njegovi namestitvi. Zahteve v zvezi s tem zato ne spadajo na področje uporabe tega dokumenta; ne glede na to so v dodatku C podana priporočila za prečni odmik.
Opozoriti je treba na lokalne predpise glede varnosti, ki lahko veljajo na mestu uporabe trakov.

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 document 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).
