Dryers and ovens, in which flammable substances are released - Safety requirements
This European Standard deals with all significant hazards, hazardous situations and hazardous events relevant to ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials.
The specific significant risks related to the use of this machinery with foodstuff and pharmaceutical products are not dealt with in this European Standard.
This European Standard is only applicable to machines which are used as intended and under the conditions which are foreseeable as malfunction by the manufacturer (see Clause 4).
For ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials, in which the concentration of these flammable substances shall not, under no circumstances, exceed 3 % of the LEL, EN 746-1 and EN 746-2 may be applied instead of this European Standard.
This European Standard is not applicable to:
— ovens for hardening metals;
— enamelling plants;
— portable heating systems for drying (for instance infrared radiant heaters, hot-air blowers, blow-dryers);
— solvent recovery plants;
— distillation and/or refraction plants;
— textile dry-cleaning systems.
This European Standard is not applicable to machinery manufactured before the date of its publication as EN.
Trockner und Öfen, in denen brennbare Stoffe freigesetzt werden - Sicherheitsanforderungen
Diese Norm behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse von Öfen und Trocknern in denen brennbare Stoffe durch Verdampfen aus und Aushärten von Beschich-tungsstoffen freigesetzt werden.
ANMERKUNG Für Trockner und Öfen, in denen z.B. Schleifscheiben, Trennscheiben, behandeltes Holz, pharmazeutische Produkte oder Nahrungsmittel getrocknet oder Keramik entbindert wird, können zusätzliche Anforderungen gelten.
Diese Norm gilt ausschließlich für Maschinen, die bestimmungsgemäß und unter Bedingungen, die vom Hersteller als Fehlanwendung vernünftigerweise vorhersehbar sind, verwendet werden (siehe Abschnitt 4).
Diese Norm gilt nicht für:
- Öfen und Trockner, in denen brennbare Stoffe durch Verdampfen aus und Aushärten von Beschich-tungsstoffen freigesetzt werden, in denen die Konzentration dieser brennbaren Stoffe unter keinen Umständen 3 % der UEG überschreitet;
ANMERKUNG 1 Für diese Maschinen sind EN 746 1 und EN 746 2 anzuwenden.
- kombinierte Spritz und Trocknungskabinen;
ANMERKUNG 2 Für kombinierte Spritz- und Trocknungskabinen ist EN 13355 anzuwenden.
- Öfen zum Härten von Metallen;
- Sinteröfen;
- Emaillieranlagen;
- ortsbewegliche Heizeinrichtungen zum Trocknen (z. B. Infrarot-Heizstrahler, Heißluft-Gebläse, Fön);
- Lösemittel Rückgewinnungsanlagen;
- Destillier- und/oder Refraktionsanlagen;
- Textilreinigungsmaschinen.
Diese Norm gilt nicht für Maschinen, die vor Veröffentlichung als EN hergestellt wurden.
Séchoirs et fours dans lesquels se dégagent des substances inflammables - Prescriptions de sécurité
La présente Norme européenne traite tous les phénomènes dangereux, situations dangereuses et événements dangereux significatifs qui sont pertinents pour les fours et séchoirs dans lesquels des substances inflammables sont dégagées par l’évaporation et le durcissement de produits de revêtement.
Les risques spécifiques significatifs liés à l'utilisation de ces machines avec des denrées alimentaires et des produits pharmaceutiques ne sont pas traités dans la présente Norme européenne.
La présente Norme européenne n’est applicable qu’aux machines utilisées normalement et aux machines faisant l’objet d’un mauvais usage raisonnablement prévisible par le fabricant (voir Article 4).
Pour les fours et séchoirs dans lesquels des substances inflammables sont dégagées par l’évaporation et le durcissement de produits de revêtement et dans lesquels la concentration de ces substances inflammables ne doit, en aucun cas, dépasser 3 % de la limite inférieure d’explosivité (LIE), l'EN 746-1 et l'EN 746-2 peuvent être appliquées au lieu de la présente Norme européenne.
La présente Norme européenne ne s'applique pas aux :
fours pour la trempe des métaux ;
installations d’émaillage ;
systèmes de chauffage portatifs utilisés pour le séchage (par exemple, radiants à rayonnement infrarouge, soufflantes d’air chaud, séchoirs soufflants) ;
installations de récupération de solvants ;
installations de distillation et/ou de réfraction ;
systèmes de nettoyage à sec de textiles.
La présente Norme européenne ne s'applique pas aux machines fabriquées avant sa date de publication en tant que norme EN.
Sušilniki in peči, v katerih se sproščajo vnetljive snovi - Varnostne zahteve
