(Main)Safety of machinery - Safety requirements for pressure metal diecasting units
Safety of machinery - Safety requirements for pressure metal diecasting units
This European Standard specifies the safety requirements for pressure metal diecasting units.
It applies to pressure diecasting machines and to the interfaces with the following ancillary equipment:
die,
melting, holding and dosing furnaces (see EN 746-1),
metal feeding equipment,
inserting and removal devices,
spraying appliances,
heat exchanger for the die.
This ancillary equipment itself is not covered.
Additional risks arising from the material being cast are not covered.
This standard does not apply to low pressure diecasting machines and/or gravity diecasting machines.
This standard deals with all significant hazards, hazardous situations and events relevant to pressure diecasting machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). It provides the requirements to be met by the manufacturer to ensure the safety of persons and property during transport, commissioning, use, de-commissioning and maintenance periods, as well as in the event of foreseeable failures or malfunctions that may occur in the equipment.
This document is not applicable to pressure metal diecasting units/machinery which are manufactured before the date of its publication as EN.
Sicherheit von Maschinen - Sicherheitsanforderungen an Metall-Druckgießanlagen
Diese Europäische Norm legt die Sicherheitsanforderungen für Metall-Druckgießanlagen fest.
Sie gilt für Druckgießmaschinen und Übergangsstellen zu folgenden Zusatzeinrichtungen:
- Druckgießform,
- Schmelz, Warmhalte- und Dosieröfen (siehe EN 746-1),
- Metallzuführeinrichtung,
- Einlege- und Entnahmegeräte,
- Sprühvorrichtungen,
- Wärmetauscher für die Druckgießform.Diese Zusatzeinrichtungen an sich sind nicht abgedeckt.
Weitere Risiken, die aus dem gegossenen Material resultieren, sind nicht abgedeckt.
Diese Norm gilt nicht für Niederdruck-Kokillengießmaschinen und/oder Schwerkraft-Kokillengießmaschinen.
Diese Norm enthält alle relevanten signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungs¬ereignisse für Druckgießmaschinen, vorausgesetzt, dass diese bestimmungsgemäß verwendet werden, sowie für vernünftigerweise durch den Hersteller vorhersehbaren Fehlgebrauch (siehe Abschnitt 4). Diese Norm enthält die vom Hersteller zu erfüllenden Anforderungen, um die Sicherheit von Personen und Gegenständen während des Transports, der Inbetriebnahme, des Betriebs, der Außerbetriebnahme und der Instandhaltung sowohl im Fall von vorhersehbaren Fehlern als auch bei Fehlfunktionen sicherzustellen, die in den Ausrüs¬tungen auftreten können.
Diese Norm gilt nicht für Metall-Druckgießanlagen/-maschinen, die vor dem Erscheinungstermin dieser Norm als EN hergestellt worden sind.
Sécurité des machines - Prescriptions de sécurité pour les chantiers de moulage des métaux sous pression
La présente Norme européenne spécifie les prescriptions de sécurité relatives aux chantiers de moulage des métaux sous pression.
Elle s'applique aux machines à couler sous pression et aux interfaces avec les équipements auxiliaires suivants :
- le moule ;
- les fours de fusion, de maintien et de dosage (voir EN 746-1) ;
- les dispositifs d'alimentation en métal ;
- les dispositifs d'amenée ou d'extraction ;
- les dispositifs de poteyage ;
- l’échangeur de chaleur du moule.
Ces équipements auxiliaires ne sont pas couverts.
Les risques additionnels provenant du matériau en cours de coulée ne sont pas couverts.
La présente norme ne s'applique pas aux chantiers de moulage à basse pression et/ou par gravité.
La présente norme traite tous les phénomènes dangereux, situations et évènements dangereux significatifs spécifiques aux chantiers de moulage sous pression, lorsqu’ils sont utilisés dans les conditions normales prévues et dans des conditions anormales telles que le constructeur a pu raisonnablement les prévoir (voir Article 4). Elle définit les prescriptions auxquelles doit satisfaire le fabricant pour assurer la sécurité des personnes et des biens pendant la construction, le transport, la mise en service, l'utilisation, la mise hors service et la maintenance, ainsi que dans le cas de pannes ou de défauts de fonctionnement prévisibles, susceptibles d'affecter le matériel.
Le présent document ne s’applique pas aux chantiers/machines de moulage des métaux sous pression qui sont fabriqués avant la date de publication de ce document par le CEN.
