BS EN 1672-1:2014EN 1672-1:2014 (E) 6 Introduction Food processing machines are used extensively in Europe, in domestic, cateri

29、ng and industrial applications. They present many health and safety hazards and have the potential to cause serious injury. At the time of publication of this European Standard there exist about 50 European C-standards for all kinds of food processing machinery. Yet, some food processing machines ar

30、e so specific and their variety is so large that it is not possible to sufficiently cover all types by machine-specific standards. EN 1672-1 therefore addresses those food processing machines that are not covered by one of the machine-specific standards that are listed in Annex C. The extent to whic

31、h hazards are covered by this document is indicated in the Scope and Clause 4. BS EN 1672-1:2014EN 1672-1:2014 (E) 7 1 Scope This European Standard deals with the significant hazards, hazardous situations and events relevant to commercial and industrial food processing machines as defined in Clause

32、3 when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with the significant hazards, hazardous situations and events that occur during transport, assembly and installation, commissioning, setti

33、ng, teaching, programming, process changeover, operation, cleaning, fault finding and maintenance. This European Standard deals with those risks which occur commonly in food processing machines and for which common technical requirements can be set which can be applied at all (or most) machines whic

34、h have that particular hazard. Exclusions: This European Standard is not applicable to the following machines: food processing machines intended for domestic use; food processing machines covered by the machine-specific standards listed in Annex C; packaging machines; machines used in the agricultur

35、al and animal rearing sectors. This European Standard does not deal with the hygiene risks to the consumer of the food product handled in the food processing machine. These risks are dealt with in EN 1672-2:2005+A1:2009. This European Standard is not applicable to food processing machines that were

36、manufactured before the date of its publication as a European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
