Plastics and rubber machines - Size reduction machines - Part 4: Safety requirements for agglomerators

This document deals with all significant hazards, hazardous situations and events relevant to agglomerators for the modification of plastic scraps in its form, size and flow characteristics, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A). The hazards have been identified taking into account all phases of the machine life cycle according to EN ISO 12100:2010, 5.4.
Machines considered in this document begin at the outer edge of the feed opening and end at the outer edge of the discharge opening.
This document does not deal with:
-   hazards due to emissions by processing materials that could be hazardous to health;
-   hazards caused by ignition of flammable residues in material to be processed;
-   requirements for exhaust ventilation systems.
This document is not applicable to agglomerators manufactured before the date of its publication.

-   die Performance Level/Sicherheits-Integritäts-Level von sicherheitsbezogenen Teilen des Steuerungssystems sind nach EN ISO 13849-1:2015 / EN 62061:2005, EN 62061:2005/A1:2013, EN 62061:2005/A2:2015 festgelegt worden;
-   die Gefährdungen in Zusammenhang mit dem Herausschleudern von Teilen oder Materialien aus der Agglomeratorkammer sind herausgenommen worden, weil zuverlässige und gut konstruierte Kammern jetzt den Stand der Technik darstellen (es ist lange nicht mehr über den Bruch einer Kammer berichtet worden);
-   Beschickungsöffnungen mit großen Abmessungen sind berücksichtigt;
-   Anforderungen für bewegliche Teile des Austragssystems sind ergänzt;
-   der Anhang zur Lärmmessung ist überarbeitet worden."

Ajouter le premier tiret suivant au 7ème alinéa : "
-   la suppression du domaine d’application des agglomérateurs dont les organes de service sont actionnés par de l'énergie pneumatique et/ou hydraulique ;"
pour lire : "
Par rapport à l’EN 12012-4:2006+A1:2008, les principales modifications concernent :
-   la suppression du domaine d’application des agglomérateurs dont les organes de service sont actionnés par de l'énergie pneumatique et/ou hydraulique ;
-   la prise en compte de la révision des normes de type A et de type B ;
-   le transfert de la liste des phénomènes dangereux en annexe informative ;
-   la spécification des niveaux de performances/des niveaux d'intégrité de sécurité des parties des systèmes de commande liées à la sécurité, suivant l'EN ISO 13849 1:2015 / l'EN 62061:2005, l'EN 62061:2005/A1:2013, l'EN 62061:2005/A2:2015 ;
-   la suppression des risques liés à l'éjection de pièces ou de matière de la chambre d'agglomération car des chambres fiables et bien conçues représentent maintenant l'état de l'art (aucune projection et aucune chambre cassée n'ont été signalées depuis longtemps) ;
-   la prise en compte des ouvertures d'alimentation de grandes dimensions ;
-   l’adjonction des exigences des parties mobiles des systèmes d'évacuation ;
-   la révision de l'annexe sur le mesurage du bruit.".

1 Modification to the European foreword
th
Add the first dash to the 7 paragraph: "
—  the agglomerators with actuators moved by pneumatic and/or hydraulic energy have been excluded
from the Scope;"
to read: "
The main changes compared to the EN 12012-4:2006+A1:2008 are:
— the agglomerators with actuators moved by pneumatic and/or hydraulic energy have been excluded
from the Scope;
— the revision of type-A and type-B standards have been considered;
— the list of significant hazards has been moved to an informative annex;
— the performance levels/safety integrity levels of safety related parts of control systems have been
specified in accordance with EN ISO 13849-1:2015 / EN 62061:2005, EN 62061:2005/A1:2013,
EN 62061:2005/A2:2015;
— the hazards related to the ejection of parts or materials from the agglomerator chamber have been
removed because reliable and well-designed chambers represent now the state of the art (no
projections and no broken chamber have been reported for a long time);
— feed openings of big dimensions are considered;
— requirements for moving parts of discharge systems are added;
— the annex for noise measurement has been revised.".
2 Modification to the Scope
In the third paragraph, third dash, make editorial modification and add an additional last dash: "
—  agglomerators moved by pneumatic and/or hydraulic energy."
to read: "
This document deals with all significant hazards, hazardous situations and events relevant to
