23、 (EN 13732:2013) has been prepared by Technical Committee CEN/TC 153 “Machinery intended for use with foodstuffs and feed”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement,

24、at the latest by January 2014, and conflicting national standards shall be withdrawn at the latest by January 2014. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying a

25、ny or all such patent rights. This document supersedes EN 13732:2002+A2:2009. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s)

26、, see informative Annex ZA, which is an integral part of this document. The main changes compared to the previous edition are the following ones: a) specification of the scope: 1) pre-cooled milk is taken into account; 2) other energy than electrical energy as well as the pressure aspect of vacuum t

27、anks are excluded; b) updating of normative references; c) specification of the electrical requirements (5.3 was revised and Annexes B and C were added); d) addition of subclause 7.2 “Warning signs”; e) specification of the noise test code; f) editorial modifications. According to the CEN-CENELEC In

28、ternal Regulations, the national standards organizations 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,

29、 Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 13732:2013EN 13732:2013 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100. The mac

30、hinery concerned and the extent to which hazards, hazardous situations and events 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 precedenc

31、e over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. BS EN 13732:2013EN 13732:2013 (E) 6 1 Scope 1.1 This European Standard specifies requirements for design, performance, safety and hygiene of refrigerated

32、bulk milk coolers and the related methods of test. This standard deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farms, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Cla

33、use 4). It applies to refrigerated bulk milk tanks with air cooled condensing units and automatic control intended for installation on farms or at milk collecting points. It applies to tanks for two milkings (24 h), four milkings (48 h) and six milkings (72 h), in which the cooling takes place total

34、ly (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. Performance requirements in 5.5.1.2.1 and 5.5.1.2.2 do not apply to tanks in combination with instant cooling or in association with a continuous system of milking (e.g. milking with robot). 1.2 This European Standar

35、d does not cover: mobile tanks; tanks intended to be tilted for drainage; equipment for delivering the milk to the tank; equipment for pre-cooling or instant cooling of the milk; the hazards due to the use of other energy than electrical energy; pression aspect of vacuum tanks. 1.3 Noise is not cons

36、idered to be a significant hazard, but a relevant one for bulk milk coolers. This standard therefore includes information in 7.1 and in Annex A concerning the manufacturers declaration of the noise emission level of the cooler. 1.4 This standard does not cover the calibration requirements for the ta

37、nk to be used as a system for payment purpose. 1.5 This standard is not applicable to bulk milk coolers on farms which are manufactured before the date of its publication as an EN.
