Plastics and rubber machines - Internal mixers - Safety requirements
This European Standard deals with all significant hazards, hazardous situations or hazardous events relevant to the design and construction of internal mixers during all phases of the machine life cycle (see EN ISO 12100:2010, 5.4), irrespective of their size and of the control modes of the feeding door and discharge door, for production and laboratory applications, when the machines are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
An internal mixer for production and a tandem mixer with manual feeding begins at the feeding door and ends at the lower edge of the material discharge opening.
An internal mixer for production and a tandem mixer with automatic feeding begins at the conveyor, which is an integral part of the machine, and ends at the lower edge of the material discharge opening.
A laboratory internal mixer begins at the feeding door and ends at the material container, which is an integral part of the mixer.
With regard to noise emission measurement and declaration, only laboratory mixers are covered.
Explosion hazards are not dealt with in this document.
NOTE Internal mixers usually do not produce explosive atmospheres. Where materials are processed, which may cause an explosive atmosphere, the Directive 2014/34/EU on the Equipment and protective systems intended for use in potentially explosive atmospheres (ATEX) can be applied.
Exhaust systems are not covered.
This European Standard is not applicable to internal mixers manufactured before the date of its publication.
Kunststoff- und Gummimaschinen - Innenmischer - Sicherheitsanforderungen
Diese Europäische Norm behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefähr-dungsereignisse, die für die Konstruktion und den Bau von Innenmischern in sämtlichen Phasen der Lebensdauer der Maschine (siehe EN ISO 12100:2010, 5.4) relevant sind, unabhängig von ihrer Größe und von den Steuerungsarten für die Beschickungsklappe und die Entleerungsklappe, wenn die Maschinen bestimmungsgemäß und unter Bedingungen, die vom Hersteller als Fehlanwendung vernünftigerweise vorhersehbar sind, verwendet werden (siehe Anhang A).
Ein Innenmischer für die Produktion und ein Tandemmischer mit manueller Beschickung beginnt an der Beschickungsklappe und endet an der unteren Kante der Materialentleerungsöffnung.
Ein Innenmischer für die Produktion und ein Tandemmischer mit automatischer Beschickung beginnt am Förderband, das integraler Bestandteil der Maschine ist, und endet an der unteren Kante der Materialentleerungsöffnung.
Ein Labor-Innenmischer beginnt an der Beschickungsklappe und endet am Materialbehälter, der integraler Bestandteil der Maschine ist.
Was die Messung und Erklärung der Lärmemission betrifft, so sind nur Labor-Innenmischer behandelt.
Gefährdungen durch Explosion werden nicht in diesem Dokument behandelt.
ANMERKUNG Innenmischer bilden in der Regel keine explosionsgefährdeten Atmosphären. Werden Materialien verarbeitet, die eine explosionsfähige Atmosphäre verursachen können, kann die Richtlinie 2014/34/EU für Geräte und Schutzsysteme zur bestimmungsgemäßen Verwendung in explosionsgefährdeten Bereichen (ATEX) angewendet werden.
Absaugsysteme werden nicht behandelt.
Diese Europäische Norm gilt nicht für Innenmischer, die vor dem Datum ihrer Veröffentlichung hergestellt wurden.
Machines pour les matières plastiques et le caoutchouc - Mélangeurs internes - Prescritions de sécurité
La présente Norme européenne traite de tous les phénomènes dangereux, situations et événements dangereux significatifs pertinents pour la conception et la fabrication des mélangeurs internes au cours de toutes les phases du cycle de vie des machines (voir l'EN ISO 12100:2010, 5.4), quels que soient leurs dimensions et les modes de commande de la porte de chargement et de la porte de déchargement, pour des applications de production et de laboratoire, lorsque ces machines sont utilisées normalement et en cas de mauvais usage raisonnablement prévisible par le fabricant (voir Annexe A).
Un mélangeur interne pour la production et un mélangeur tandem à chargement manuel commencent à la porte de chargement et se terminent au bord inférieur de l'ouverture de déchargement des matériaux.
Un mélangeur interne pour la production et un mélangeur tandem à chargement automatique commencent au convoyeur, qui est une partie intégrale de la machine, et se terminent au bord inférieur de l'ouverture de déchargement des matériaux.
Un mélangeur interne de laboratoire commence à la porte de chargement et se termine au conteneur de matériaux, qui est une partie intégrale du mélangeur.
En ce qui concerne le mesurage et la déclaration des émissions de bruit, seuls les mélangeurs de laboratoire sont couverts.
Le présent document ne traite pas des risques d'explosion.
NOTE En général les mélangeurs internes ne génèrent pas d'atmosphères explosibles. Lorsque les matériaux travaillés peuvent engendrer une atmosphère explosible, la directive 2014/34/UE pour les appareils et les systèmes de protection destinés à être utilisés en atmosphères explosibles (ATEX) peut-être appliquée.
Les systèmes d'aspiration ne sont pas couverts.
La présente Norme européenne ne s'applique pas aux mélangeurs internes fabriqués avant sa date de publication comme Norme européenne.
Stroji za predelavo gume in plastike - Notranji mešalniki - Varnostne zahteve
Ta evropski standard opisuje vsa večja tveganja, nevarne situacije ali nevarne dogodke v zvezi z načrtovanjem in izdelavo notranjih mešalnikov za uporabo v proizvodnji in laboratorijih, kadar se uporabljajo v skladu z svojim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določi proizvajalec (glej dodatek A).
Notranji mešalnik sega od odprtin za polnjenje do odprtine za izmet.
Notranji mešalniki običajno ne proizvajajo eksplozivnih atmosfer. Če se obdelujejo materiali, ki lahko ustvarijo eksplozivno atmosfero, je treba uporabiti Direktivo 94/9/ES v zvezi z opremo in zaščitnimi sistemi, namenjenimi za uporabo v potencialno eksplozivnih atmosferah (ATEX). Ta dokument ne zajema nevarnosti eksplozije.
Varnostne zahteve za načrtovanje izpušnih sistemov in pomožne opreme niso zajete. Varnostne zahteve za interakcijo med notranjimi mešalniki in pomožno opremo so zajete.
Ta evropski standard se ne uporablja za notranje mešalnike, izdelane pred objavo tega standarda.
