Fördergurte für die Verwendung unter Tage - Elektrische und brandtechnische Sicherheitsanforderungen

Diese Europäische Norm legt elektrische und brandtechnische Sicherheitsanforderungen an Fördergurte für den Einsatz unter Tage bei entflammbarer und nicht entflammbarer Atmosphäre fest.
Fördergurte, die unter diese Europäische Norm fallen, sind vorgesehen für den Gebrauch in Förderanlagen beim Einsatz in entflammbaren Atmosphären (Bergwerken). Der Gurt ist ein Teil der Fördereinrichtung, die eine Ausrüstung nach Gruppe I, Kategorie M2 darstellt, wie in EN 13463-1:2009, 3.2.2 definiert.
Diese Europäische Norm ist nicht auf die in EN 873 beschriebenen leichten Fördergurte anwendbar und auch nicht auf Fördergurte, die vor dem Datum der Veröffentlichung dieses Dokuments durch CEN hergestellt wurden.
Diese Europäische Norm behandelt die in A.1 aufgeführten signifikanten Gefahren.
Aufmerksamkeit wird auf die Anhänge ZA und ZB gelenkt.
ANMERKUNG Tabelle 2 gibt eine Zusammenfassung der Anforderungen dieser Europäischen Norm.

Courroies transporteuses pour usage dans les installations souterraines - Prescriptions de sécurité électrique et protection contre l'inflammation

La présente Norme Européenne spécifie des prescriptions en matière de sécurité électrique et de protection contre l’inflammation, pour les courroies transporteuses destinées à être utilisées dans des installations souterraines, en atmosphères inflammables ou non inflammables.
Les courroies transporteuses couvertes par la présente Norme européenne et destinées à être utilisées en atmosphères inflammables sont destinées aux installations de convoyeur par bandes (machines dans les mines). La courroie est un composant ou une partie d’un équipement, qui peut être incorporé dans le convoyeur, qui est lui-même un équipement du Groupe 1, Catégorie M2, tel que défini en 3.2.2 de l'EN 13463 1:2009.
La présente Norme européenne n’est pas applicable aux courroies transporteuses légères telles que décrites dans l'EN ISO 21183 1:2006, ni aux courroies transporteuses qui ont été fabriquées avant la date de publication du présent document par le CEN.
La présente Norme européenne traite des phénomènes dangereux significatifs détaillés en A.1.
L’attention est attirée sur l’Annexe ZA et l'Annexe ZB.
NOTE   Un résumé des prescriptions de la présente Norme européenne est donné au Tableau 2. Ceci est destiné à une consultation rapide uniquement.

Naprave za kontinuirni transport - Trakovi tračnih transporterjev za podzemno vgradnjo - Električne in požarnovarnostne zahteve

Ta evropski standard določa električne in požarnovarnostne zahteve za trakove tračnih transporterjev, namenjenih za uporabo pri podzemnih vgradnjah, v prisotnosti vnetljivih ali nevnetljivih atmosfer.
Trakovi tračnih transporterjev, ki jih pokriva ta evropski standard in so namenjeni za uporabo v vnetljivih atmosferah, so namenjeni za uporabo v inštalacijah trakov tračnih transporterjev (stroji v rudnikih). Trak je komponenta ali del opreme, ki ga je mogoče vgraditi v tračni transporter, ki je oprema skupine I, kategorije M2, kot je opredeljeno v točki 3.2.2 v standardu EN 13463-1:2009.
Ta evropski standard ne velja za lahke trakove tračnih transporterjev, kot je opisano v standardu EN ISO 21183-1:2006, niti za trakove tračnih transporterjev, izdelane pred datumom objave tega dokumenta s strani združenja CEN.
Ta evropski standard obravnava večje nevarnosti, opredeljene pod točko A.1. Posebna pozornost je namenjena dodatkoma ZA in ZB. OPOMBA V preglednici 2 je podan povzetek zahtev tega evropskega standarda. To je namenjeno samo za hitri pregled.
