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.

Le présent document traite de tous les phénomènes dangereux, situations et événements dangereux significatifs pertinents pour des agglomérateurs utilisés pour la modification de la forme, de la taille et des caractéristiques d'écoulement des déchets de matières plastiques, lorsqu’ils sont utilisés normalement et dans des conditions de mauvais usage raisonnablement prévisible par le fabricant (voir l'Annexe A). Les phénomènes dangereux ont été identifiés en prenant en compte toutes les phases du cycle de vie de la machine, conformément à l'EN ISO 12100:2010, 5.4.
Les machines prises en compte dans le présent document commencent au bord extérieur de l'ouverture d'alimentation et se terminent au bord extérieur de l'ouverture d'évacuation.
Le présent document ne traite pas :
-   des phénomènes dangereux engendrés par les émissions dues à la transformation des matières qui pourraient être dangereuses pour la santé ;
-   des phénomènes dangereux engendrés par l'inflammation de résidus inflammables dans les matières à traiter ;
-   des exigences relatives aux systèmes d'aspiration ;
-   des agglomérateurs actionnés par de l'énergie pneumatique et/ou hydraulique.
Le présent document n’est pas applicable aux agglomérateurs fabriqués avant sa date de publication.

European foreword
This document (EN 12012-4:2019+A1:2021) has been prepared by Technical Committee CEN/TC 145
“Plastics and rubber machines”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2022, and conflicting national standards shall be
withdrawn at the latest by April 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes !EN 12012-4:2019".
The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
The main changes compared to the EN 12012-4:2006+A1:2008 are:
— 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 agglomerators with actuators moved by pneumatic and/or hydraulic energy have been
excluded from the Scope;"
— the annex for noise measurement has been revised.
!In comparison with the original version EN 12012-4:2019, the following technical and editorial
modifications have been made by amendment EN 12012-4:2019/A1:2021:
