This European Standard shall be given the statu

30、s of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2018 and conflicting national standards shall be withdrawn at the latest by July 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of

31、patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12013:2000+A1:2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports

32、 essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. The main changes with respect to the previous edition are as follows: modification of the structure; list of significant hazards is moved into an i

33、nformative annex; clarification that internal mixers for production and for laboratory applications are dealt with; tandem mixers (combination of two internal mixers) are added; technical developments in safeguards are taken into account; revised type-A and type-B standards are taken into account; t

34、he performance levels of safety related parts of control systems are specified in accordance with EN ISO 13849-1:2015; normative annex on noise measurement and declaration for laboratory internal mixers is added. According to the CEN-CENELEC Internal Regulations, the national standards organizations

35、 of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, N

36、etherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 12013:2018EN 12013:2018 (E) 5 Introduction This document is a type-C standard as stated in EN ISO 12100:2010. This document is of relevance, in particular, for

37、the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance etc.) Others can be affected by the level of mac

38、hinery safety achieved with the means of the document by the above-mentioned stakeholder groups: machine users/employers (small, medium and large enterprises); machine users/employees (e.g. trade unions, organizations for people with special needs); service providers, e.g. for maintenance (small, me

39、dium and large enterprises); consumers (in case of machinery intended for use by consumers). The above-mentioned stakeholder groups have been given the possibility to participate at the drafting process of this document. The machinery concerned and the extent to which hazards, hazardous situations o

40、r hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are stated in type-A or type-B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for mac

41、hines that have been designed and built according to the requirements of this type-C standard. BS EN 12013:2018EN 12013:2018 (E) 6 1 Scope This European Standard deals with all significant hazards, hazardous situations or hazardous events relevant to the design and construction of internal mixers du

42、ring all phases of the machine life cycle (see EN ISO 12100:2010, 5.4), irrespective of their size and of the control modes of the feeding door and discharge door, for production and laboratory applications, when the machines are used as intended and under the conditions of misuse which are reasonab

43、ly foreseeable by the manufacturer (see Annex A). An internal mixer for production and a tandem mixer with manual feeding begins at the feeding door and ends at the lower edge of the material discharge opening. An internal mixer for production and a tandem mixer with automatic feeding begins at the

44、conveyor, which is an integral part of the machine, and ends at the lower edge of the material discharge opening. A laboratory internal mixer begins at the feeding door and ends at the material container, which is an integral part of the mixer. With regard to noise emission measurement and declarati

45、on, only laboratory mixers are covered. Explosion hazards are not dealt with in this document. NOTE Internal mixers usually do not produce explosive atmospheres. Where materials are processed, which may cause an explosive atmosphere, the Directive 2014/34/EU on the Equipment and protective systems i

46、ntended for use in potentially explosive atmospheres (ATEX) can be applied. Exhaust systems are not covered. This European Standard is not applicable to internal mixers manufactured before the date of its publication. 2 Normative references The following documents, in whole or in part, are normative
