European foreword
This document (EN 12012-4:2019/prA1:2021) has been prepared by Technical Committee CEN/TC 145
“Plastics and rubber machines”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document is an Amendment to EN 12012-4:2019.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
In comparison with the previous edition, the following technical and editorial modifications have been
made:
— European Foreword: dash added;
— Scope: editorial modification and dash added;
— Normative references: a reference date updated;
— 4.2.1: updated normative references;
— 4.2.3: updated normative reference;
— 4.6.1.3: modified text;
— 4.6.1.4: modified text;
— 4.7.2: modified text;
— 4.7.3: updated normative reference;
— 6.2.1: modified text;
— 6.3.2: modified text;
— Table Annex ZA: modified text.

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
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;
 agglomerators moved by pneumatic and/or hydraulic energy.
