Machines for surface cleaning and pre-treatment of industrial items using liquids or vapours - Part 3: Safety of machines using flammable cleaning liquids
This European Standard deals with the significant hazards of machines for surface cleaning and pre-treatment - in the following called "cleaning machines" - of industrial items using flammable cleaning liquids or a mixture of cleaning liquids, even in emulsion form, which can potentially create, even temporarily, a condition of flammability.
This European Standard applies in combination with EN 12921-1. 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 this European Standard take precedence over the respective requirements of EN 12921-1.
To the extent of this document the terms combustible materials and flammable substance and explosive are equivalently used.
NOTE 1 The condition of flammability can be generated only when molecules of the fluid are in intimate contact with oxygen from the air. Ignition is possible when: the fluid generates a concentration of vapour in air, or: the flammable fluid is present as a suspension of fine droplets in air (aerosol).
NOTE 2 In practice, fires and explosions differ by the size and intensity of the reaction, and by the instantaneous effects on the environment.
This European Standard does not apply to machinery and related equipment excluded from the scope of
EN 12921-1.
This European Standard is not applicable to cleaning machines of industrial items using flammable cleaning liquids which are manufactured before the publication of this European Standard by CEN.

Diese Europäische Norm behandelt signifikante Gefährdungen von Maschinen zur Oberflächenreinigung und -vorbehandlung - im Folgenden Reinigungsanlagen genannt - von industriellen Produkten, in denen brennbare Reinigungsflüssigkeiten oder ein Gemisch aus Reinigungsflüssigkeiten verwendet werden, auch in Form von Emulsionen, durch die möglicherweise, auch nur zeitweise, ein brennbarer Zustand erreicht werden kann.
Diese Europäische Norm ist in Verbindung mit EN 12921-1:2005 anzuwenden. 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 in dieser Europäischen Norm beschriebenen spezifischen Anforderungen gelten vor den entsprechenden Anforderungen von EN 12921-1:2005.
Im Sinne dieser Europäische Norm werden die Begriffe brennbar und explosionsfähig äquivalent verwendet.
ANMERKUNG 1 Eine Flüssigkeit kann nur bei engem Kontakt ihrer Moleküle mit Luftsauerstoff brennen. Eine Zündung ist möglich, wenn sich Dampf aus der Flüssigkeit in der Luft anreichert oder die brennbare Flüssigkeit als feine Verteilung kleiner Tröpfchen in der Luft vorliegt (Aerosole).
ANMERKUNG 2 In der Praxis unterscheiden sich Brände und Explosionen in Ausmaß und Intensität der Reaktion und durch die momentanen Auswirkungen auf die Umwelt.
Diese Europäische Norm gilt nicht für Maschinen und deren Ausrüstung, die vom Anwendungsbereich der EN 12921-1:2005 ausgeschlossen sind.
Diese Europäische Norm gilt nicht für Reinigungsanlagen von industriellen Produkten, in denen brennbare Flüssigkeiten verwendet werden, die vor Veröffentlichung dieser EN durch CEN hergestellt wurden.
Machines de nettoyage et de prétraitement de pièces industrielles utilisant des liquides ou des vapeurs - Partie 3: Sécurité des machines utilisant des liquides de nettoyage inflammables
La présente Norme européenne ne traite que des phénomènes dangereux significatifs des machines de nettoyage et de pré-traitement — appelées dans la suite du texte «machines de nettoyage» — de pièces industrielles utilisant des liquides de nettoyage inflammables ou des mélanges de liquides de nettoyage, même sous la forme d’émulsion, susceptibles de créer, même temporairement, des conditions favorables à l’inflammation.
La présente Norme européenne s'applique conjointement avec l’EN 12921-1. L’ensemble de ces deux parties couvre de tous les phénomènes dangereux significatifs communs aux machines utilisant des liquides ou des vapeurs, lorsqu’elles sont utilisées comme prévu et dans les conditions prévues par le fabricant (voir Article 4). Les prescriptions particulières spécifiées dans la présente Norme européenne prévalent sur les prescripions correspondantes de l’EN 12921-1.
Dans le présent document, «matériau combustible» est également appelée «substance inflammable» ou «explosible».
NOTE 1 Les conditions d’inflammabilité ne peuvent être générées que lorsque des molécules de fluide sont intimement en contact avec l’oxygène de l’air. L’inflammation est possible lorsque : le fluide génère une concentration de vapeur dans l’air ou le fluide inflammable est en suspension sous forme de fine gouttelettes dans l’air (aérosols).
NOTE 2 En pratique, les explosions et les incendies diffèrent par la taille et l’intensité de la réaction et par les effets instantanés sur l’environnement.
La présente Norme européenne ne s'applique pas aux machines et équipements annexes exclus du domaine d'application de l’EN 12921-1.
La présente Norme européenne ne s'applique pas aux machines de nettoyage de pièces industrielles utilisant des liquides de nettoyage inflammables fabriquées avant la publication de la présente Norme européenne par le CEN.
