Bibliography

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
