EN 12921-4:2005

Machines for surface cleaning and pretreatment of industrial items using liquids or vapours - Part 4: Safety of machines using halogenated solvents

This European Standard specifies the significant hazards of machines for surface cleaning and pre-treatment - in the following called "cleaning machines" - of industrial items using halogenated solvents, either pure or as a mixture.
This European Standard applies together with EN 12921-1:2005. Both parts together cover all significant hazards relevant for cleaning machines of industrial items using liquids or vapours, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). The specific requirements specified in Part 4 take precedence over the respective requirements in EN 12921-1:2005.
This European Standard applies together with EN 12921-3 in case of release of flammable vapours from the cleaning liquids.
This European Standard does not apply to machinery and related equipment excluded from the scope of EN 12921-1:2005.
This European Standard is not applicable to cleaning machines which are manufactured before the publication of this European Standard by CEN.

Maschinen zur Oberflächenreinigung und -vorbehandlung von industriellen Produkten mittels Flüssigkeiten oder Dampfphasen - Teil 4: Sicherheit von Maschinen, in denen halogenierte Lösemittel verwendet werden

Diese Europäische Norm behandelt signifikante Gefährdungen von Maschinen zur Oberflächenreinigung
und -vorbehandlung � im Folgenden "Reinigungsanlagen" genannt � von industriellen Produkten, in denen
halogenierte Lösemittel (rein oder als Gemisch) verwendet werden.
Diese Europäische Norm gilt nur in Verbindung mit EN 12921-1:2005. Zusammen decken beide Teile alle
signifikanten Gefährdungen für Reinigungsanlagen für industrielle Produkte in denen Flüssigkeiten oder
Dampfphasen verwendet werden, wenn sie bestimmungsgemäß und unter den vom Hersteller vorgesehenen
Bedingungen verwendet werden (siehe Abschnitt 4). Die spezifischen Anforderungen in diesem Teil haben
Vorrang vor vergleichbaren Vorschriften in EN 12921-1:2005.
Bei einem Freisetzen von brennbaren Dämpfen aus der Reinigungsflüssigkeit muss diese Europäische Norm
zusammen mit EN 12921-3:2005 angewendet werden.
Diese Europäische Norm gilt nicht für Maschinen und deren Ausrüstung, die durch den Anwendungsbereich
der EN 12921-1:2005 ausgeschlossen sind.
Diese Europäische Norm gilt nicht für Reinigungsanlagen, die vor Veröffentlichung dieser Europäische Norm
durch CEN hergestellt wurden.

Machines de nettoyage et de prétraitement de pièces industrielles utilisant des liquides ou des vapeurs - Partie 4: Sécurité des machines utilisant des solvants halogénés

Cette norme s'applique aux machines, installations et équipements annexes destinés à être utilisés pour le nettoyage et le prétraitement de pièces industrielles par des procédés utilisant des solvants halogénés, purs ou en mélange. Si un ou plusieurs solvants halogénés sont mélangés avec un ou plusieurs solvants inflammables, EN 12921-4 s'applique. Les machines peuvent utiliser différentes techniques de nettoyage telles que l'immersion dans le liquide, la condensation de vapeur, la pulvérisation de liquide et des combinaisons de ces techniques.
