EN 12854:2003 (E) 4 Introduction The use of beam mixers generates various mechanical and other hazards. Their extensive use justifies the need of a standard covering both safety and the hazards of food hygiene arising from machine design, complementary to EN 1672-2 which states general hygiene requirements for food processing machines. This standard is a harmonised standard which provides one means of conformity with the essential safety and hygiene requirements of the Machinery Directive and associated EFTA Regulations. This European standard is a type C standard as stated in EN 1070:1998. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. 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 designed and built according to the provisions of this type C standard. EN 12854:2003 (E) 5 1 Scope 1.1 This European standard specifies the safety and hygiene requirements for the design and manufacture of beam mixers. Beam mixers are used in the catering industry for the preparation of mixture or emulsion, directly in the cooking pan, such as for : puree, mayonnaise, sauces, soups, compotes. It applies to the design, installation, operation and maintenance of such machines when they are used to operate under the intended conditions of use as defined in 3.12 of EN 292-1:1991 and stated in the instruction handbook (see 7.1), including cleaning, and changing the tools. 1.2 This European standard does not apply to: ? domestic machines; ? portable hand-held blenders and whisks which are covered by a specific standard (see EN 12853:2001). 1.3 This standard covers significant hazards at such machines, as identified by risk assessment (see EN 1050:1996), which are listed in clause 4 of this standard. 1.4 This European standard does not deal with the vibration hazard. 1.5 This European standard applies primarily to the machines which are manufactured after its date of issue. EN 12854:2003 (E) 6 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment of revision.
