Foundry Machinery - Safety requirements for abrasive blasting equipment

This standard specifies requirements to be met by the manufacturer of abrasive blasting equipment for the foreseeable significant hazards due to design, construction and installation, during commissioning, operation, maintenance and decommissioning of the equipment which employ either centrifugal force or compressed air as a means of accelerating abrasive to achieve the desired result.
Abrasive blasting equipment covers:
- centrifugal blasting machines;
- air blasting machines;
- loading, conveying and unloading systems for the workpieces.
See Annex A for more details.
This standard covers all foreseeable significant hazards which could be encountered during the lifetime of the machine as listed in clause 5.
This standard does not apply to:
- mobile centrifugal blasting equipment;
- mobile air blasting equipment;
- wet blasting equipment;
- the general works compressed air supply system.

Gießereimaschinen - Sicherheitsanforderungen für Strahlanlagen

Diese Norm beschreibt die vom Hersteller von Strahlanlagen zu beachtenden Anforderungen für die vor-hersehbaren
signifikanten Gefährdungen aufgrund Konstruktion, Errichtung und Einbau, bei Inbetrieb-nahme,
Betrieb, Wartung und Außerbetriebnahme der Anlagen, die entweder Zentrifugalkraft oder Druck-luft
als Hilfsmittel zur Beschleunigung des Strahlmittels nutzen, um das gewünschte Ergebnis zu errei-chen.
Strahlanlagen umfassen:
¿ Schleuderstrahlmaschinen;
¿ Druckluftstrahlmaschinen;
¿ Belade-, Transport- und Entladesysteme für die zu strahlenden Teile.
Für weitere Einzelheiten siehe Anhang A.
Diese Norm erfasst alle vorhersehbaren signifikanten Gefährdungen, die im Verlauf der Lebensdauer der
Maschine auftreten können, wie im Abschnitt 5 aufgeführt.
Diese Norm gilt nicht für:
¿ mobile Schleuderstrahlgeräte;
¿ mobile Druckluftstrahlgeräte;
¿ Nass-Strahlgeräte;
¿ das allgemeine Druckluftzufuhrsystem für das Werk.

Machines de fonderie - Prescriptions de sécurité pour équipements de grenaillage

Domaine d'application
La présente norme spécifie les prescriptions, auxquelles le fabricant doit satisfaire, relatives aux phénomènes dangereux significatifs prévisibles dus à la conception, à la construction et à l'installation, à la mise en service, au fonctionnement, à la maintenance et à la mise hors service des équipements qui utilisent la force centrifuge ou l'air comprimé comme moyen d'accélérer la grenaille pour obtenir le résultat désiré.
