Safety requirements for superabrasive products

This document applies to superabrasives products containing natural or synthetic diamond or cBN (cubic boron nitride). It includes precision grinding and cutting-off wheels, non-precision cutting-off wheels, diamond wires, mounted points and other superabrasive products for non-precision grinding. It also applies to reconditioned superabrasive cutting-off wheels.
This document specifies requirements and/or measures for the removal or reduction of hazards resulting from the design and application of the superabrasive products.
This document contains also procedures and tests for verification of the compliance with the requirements as well as safety information for use, which will be made available to the user by the manufacturer.
This document does not apply to bonded abrasive products, coated abrasive products, rotating dressing tools, truers or any non-rotating superabrasive products.

Dies beinhaltet Präzisionsschleif- und  trennschleif-scheiben, Trennschleifscheiben zur Bearbeitung von Naturstein und zum Einsatz im Hoch- und Tiefbau, Sägeseile, Schleifstifte und andere Schleifwerkzeuge mit Diamant oder Bornitrid zum Schleifen von Naturstein und zum Einsatz im Hoch- und Tiefbau. Es gilt auch für wiederbelegte Trennschleifscheiben mit Diamant oder Bornitrid.
Dieses Dokument legt Anforderungen und/oder Maßnahmen zur Beseitigung oder Verringerung von Gefährdungen fest, die von der Gestaltung und Anwendung der Schleifwerkzeuge mit Diamant oder Bornitrid herrühren.
Dieses Dokument umfasst auch Verfahren und Prüfungen zur Feststellung der Übereinstimmung mit den Anforderungen sowie Benutzerinformationen, die der Hersteller dem Anwender zur Verfügung stellt.
Dieses Dokument gilt nicht für Schleifkörper aus gebundenem Schleifmittel, Schleifmittel auf Unterlagen, rotierende Abrichtwerkzeuge, Handfeilen und andere nicht rotierende Schleifwerkzeuge mit Diamant oder Bornitrid.

Prescriptions de sécurité pour les produits superabrasifs

Le présent document s'applique uniquement aux produits superabrasifs contenant du diamant naturel ou synthétique ou du cBN (nitrure de bore cubique). Il comprend les meules et meules à tronçonner de précision, meules à tronçonner ordinaires, câbles diamantés, meules sur tige et autres produits superabrasifs pour meulage ordinaire. Il s'applique également aux meules à tronçonner superabrasives reconditionnées.
Le présent document spécifie les prescriptions et/ou mesures pour la suppression ou la réduction des phénomènes dangereux résultant de la conception et de l'utilisation des produits superabrasifs.
Le présent document contient également les procédures et essais pour la vérification de la conformité aux prescriptions ainsi que les informations de sécurité pour l'utilisation qui seront mises à la disposition de l'utilisateur par le fabricant.
Le présent document ne s'applique pas aux produits abrasifs agglomérés, produits abrasifs appliqués, outils à dresser rotatifs, outils à dresser, ni aux produits superabrasifs non rotatifs.

Varnostne zahteve za superabrazive

Ta evropski standard se uporablja le za superabrazive, ki vsebujejo naravne ali sintetične diamante ali kubne borove nitride (cBN). Vključuje plošče za precizno brušenje in rezanje, neprecizne plošče za rezanje, diamantne žice, nameščene konice in druge superabrazive za neprecizno brušenje. Prav tako se uporablja za superabrazivne obnovljene plošče za rezanje.
Ta evropski standard določa zahteve in/ali ukrepe za odpravo ali zmanjševanje nevarnosti, ki so posledica načrtovanja in uporabe superabrazivov.
Ta evropski standard vključuje tudi postopke in preskuse za preverjanje skladnosti z zahtevami in varnostnimi informacijami za uporabo, ki jih mora proizvajalec priskrbeti uporabniku.
Obravnavane nevarnosti so naveden v točki 4.
Ta evropski standard se ne uporablja za vezane abrazive, prevlečene abrazive, rotacijsko orodje za brušenje, brusilce niti za katere koli druge nerotacijske superabrazive.
