Machine tools - Safety - Electro Discharge Machines

1.1This standard specifies technical safety requirements and measures, applicable to EDM equipment and EDM system (e.g. for spark erosion-sinking, spark erosion-wire cutting), to be adopted by persons undertaking the design, construction, installation and/or supply of such equipment. This standard also includes information to be provided by the manufacturer to the user.
1.2 The design requirements of this standard shall not apply to arc eroding and electro chemical machining equipment.
1.3 This standard takes account of the intended use in normal workshop environment and non explosive atmospheres including installation, setting, maintenance, repair and dismantling for removal or disposal of EDM equipment.
1.4 This standard also applies to auxiliary devices essential for EDM processing.
1.5 This standard deals with specific hazards defined in clause 4, Table 1, and the measures of prevention in clause 5, Table 2.
1.6 This standard applies to machines built after its date of issue.
NOTE  Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.

Anwendungsbereich
1.1 Diese Norm legt technische Sicherheitsanforderungen und -maßnahmen für die EDM-Einrichtung und
die EDM-Anlage (z. B. Senkerodieren oder Drahterodieren) fest, die von Konstrukteuren, Herstellern, Inbetrieb-nehmern
und/oder Lieferanten von diesen Einrichtungen anzuwenden sind. Diese Norm enthält auch
Informationen, die dem Anwender durch den Hersteller zur Verfügung gestellt werden müssen.
1.2 Diese Norm gilt nicht für Maschinen zur Lichtbogenerosion oder elektrochemischen Bearbeitung.
1.3 Die in dieser Norm enthaltenen Anforderungen beziehen die bestimmungsgemäße Verwendung unter
üblichen Werkstattbedingungen in nicht explosionsfähiger Atmosphäre einschließlich Installation, Einrichten,
Wartung, Reparatur und Demontage zur Standortänderung oder Entsorgung von EDM-Einrichtungen mit ein.
1.4 Diese Norm gilt auch für Zusatzeinrichtungen, die für die EDM-Bearbeitung erforderlich sind.
1.5 Diese Norm behandelt spezifische Gefährdungen, die in Abschnitt 4, Tabelle 1, und die Schutzmaß-nahmen,
die in Abschnitt 5, Tabelle 2, aufgelistet sind.
1.6 Diese Norm gilt für Maschinen, die nach dem Erscheinungsdatum der Norm hergestellt werden.
ANMERKUNG Die Richtlinie 94/9/EG bezüglich Geräte und Schutzsysteme zur bestimmungsgemäßen Verwendung in
explosionsgefährdeten Bereichen kann bei Maschinen oder Bauteilen nach dieser Europäischen Norm zur Anwendung
kommen. Die vorliegende Norm ist nicht als Mittel zum Nachweis der Übereinstimmung mit den grundlegenden Gesund-heits-
und Sicherheitsanforderungen der Richtlinie 94/9/EG vorgesehen.
