BS EN 1114-1:2011EN 1114-1:2011 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and event
27、s are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been design
28、ed and built according to the provisions of this type C standard. BS EN 1114-1:2011EN 1114-1:2011 (E) 6 1 Scope This European Standard specifies all significant hazards, hazardous situations and events relevant to all types of screw extruders for plastics and rubber, when they are used as intended a
29、nd under conditions of misuse which are foreseeable by the manufacturer (see Clause 4). This European Standard additionally covers the following feeding systems: hoppers; single roller feed; double roller feed; crammer feeder; and the following ancillary equipment which form part of or are attached
30、to the extruder: screen changers; melt/gear pumps; melt pipes and adaptors; static mixers; extruder head that give initial shape to the extruded material. NOTE Metering devices are not covered by this standard. This European Standard does not deal with hazards caused by the processing of materials a
31、nd which may lead to a risk of fire or release of health hazardous materials. An extruder conforming to this document is not regarded as a pressure vessel as defined in the Pressure Equipment Directive 97/23/EC. Extruders usually do not produce explosive atmospheres. Where materials are processed, w
32、hich may cause an explosive atmosphere, the Directive 94/9/EC on the Equipment intended for use in Potentially Explosive Atmospheres (ATEX) should be applied. Explosion hazards are not dealt with in this document. This European Standard is not applicable to extruders which are manufactured before th
33、e date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the application of this document.
