Relationship between this European Standard and the Essential Requirements of EU Directive 98/37/EC.20 Bibliography.21

1 Scope This European Standard specifies the essential safety requirements applicable to the design and construction of agglomerators used to densify plastic scrap, reducing its size and/or volume. The limits of the agglomerator are as follows:  the outer edge of the feed opening, or outer edge of the fixed feed device (e.g. hopper) or the interface between the feed system (e.g. conveyor) and the agglomerator chamber and  the outer edge of the discharge opening of the agglomerator chamber or the interface between the agglomerator chamber and the discharge system. Only the significant hazards listed in Clause 4 and dealt with in Clause 5 are subject to this European Standard. This European Standard does not deal with hazards caused by processing materials (such as Expanded Polystyrene (EPS) and Polyurethane (PU) foam) which, when heated, may lead to a risk of fire and release of toxic gases. This European Standard does not deal with hazards caused by upstream and/or downstream equipment. This European Standard is not applicable to agglomerators manufactured before the date of its approval as EN. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The material is cut or kneaded, mixed, heated by friction and, thus, densified, if required by using water. Feeding the scrap can be by hand or by feed system 3.2 opening in the agglomerator chamber opening designed and constructed for feeding the material, discharging the material, inspecting the process inside the agglomerator chamber and/or maintaining the blades
3.3 blade cutting/kneading tool, that can be fixed or rotating and is used to cut/knead and heat by friction the material being processed 3.4 feed system power operated equipment (conveyor belts, nip roll feeders, feed screws etc.) used to feed the agglomerator

EN 1088:1995 such that the guard remains closed and locked until all motion of the blade has ceased. Safety related parts of the control system shall be according to category 3 of EN 954-1:1996. If the fixed feed device or feed system, or the part of the agglomerator chamber containing the feed opening, or the discharge system, is capable of being moved out of position and the resulting access to the agglomerator chamber does not comply with the safety distances for upper and lower limbs described in
EN 294:1992, Tables 3 or 4 and EN 811:1996, then it shall act as an interlocking guard with guard locking in accordance with EN 953:1997, 3.6 and EN 1088:1995 such that it remains locked in position until all motion of the blade has ceased. Safety related parts of the control system shall be according to category 3 of
EN 954-1:1996. To avoid any motion of movable parts during the changing or adjusting of blades, appropriate devices and/or tools shall be provided. See 7.1.3, 7.1.4, 7.1.5, 7.1.6 and 7.1.7. 5.2.2 Feed material that is not pre-cut If a power operated feed device is fitted to an agglomerator processing continuous films, fibres, strands or similar materials likely to cause entanglement, mechanically actuated sensitive protective equipment (e.g. pressure sensitive mat), in accordance with 3.26.5 of EN 12100-1:2003 shall be provided at the feed opening
