• Tên tiếng Anh / Title in English: Plastics and rubber machines - Reaction moulding machines - Part 1: Safety requirements for metering and mixing units
• Phạm vi áp dụng / Scope of standard: This European Standard specifies the essential safety requirements for compression moulding machines and transfer moulding machines for the moulding of plastics and/or rubber with a closing movement more than 6 mm. In this document a compression moulding machine or transfer moulding machine as described above is designated by the term “press” (see 3.1). This document deals with all significant hazards, hazardous situations and events relevant to presses, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). The safety requirements are specified for the additional hazards arising from: - shuttle/turn tables used for loading/unloading and/or cooling, - magnetic clamping systems. For other ancillary equipment, as defined in 3.7, that is not part of the press, only the requirements for the interaction between presses and ancillary equipment, especially loading and unloading devices are specified. The following machines or units are excluded: - pneumatic presses for plastic and rubber; - injection moulding machines (see EN 201:2009); - tyre curing machines (see prEN 16474); - presses for curing inner tubes and curing bags; - hydraulic presses for the cold working of metals as covered by EN 693:2001+A2:2011; - mechanical presses for the cold working of metals as covered by EN 692:2005+A1:2009; - pneumatic presses for the cold working of metals as covered by EN 13736:2003+A1:2009; - thermoforming machines (see EN 12409:2008+A1:2011); - reaction injection moulding (RIM) machines (see EN 1612 1:1997+A1:2008); - the extruder of the carousel machine(see EN 1114 1:2011). This standard does not cover: - hazards caused by the processing of materials which may lead to a risk of explosion, see 7.2.2; - the requirements of Directive 94/9/CE concerning equipment and protective systems intended for use in potentially explosive atmospheres; - requirements for the design of exhaust ventilation systems, see 5.3.5 and 7.2.8. This document is not applicable to presses manufactured before the date of its publication as EN.
