24、 the need of a standard covering both safety and the hazards to food hygiene. This European Standard is a type C standard as stated in EN ISO 12100.“ The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. When
25、 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 standar

BS EN 12852:2001+A1:2010EN 12852:2001+A1:2010 (E) 5 1 Scope 1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of food processors and blenders. It applies to food processors and blenders having a bowl which is stationary while the food is being
27、 processed. The total volume of the bowl is less than or equal to 150 l. The machines covered by this standard are intended to carry out various types of operations such as: mincing, mixing, blending, whipping, using a large number of products and raw materials, and which are used in food and cateri
28、ng industries such as restaurants, hotels, coffee shops and pubs. !This European Standard specifies all significant hazards, hazardous situations and events relevant to food processors and blenders, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the
29、 manufacturer (see Clause 4). This European Standard deals with the hazards which can arise during commissioning, operation, cleaning, removal of food blockages, feeding, changing the tools, maintenance and decommissioning of the machine.“ 1.2 This standard does not apply to: domestic machines; mach
30、inery dedicated to food industrial processing (e.g. pet food, cannery industry, industrial meat processing). Small machines called “shakers“ which are dedicated to blending liquid, with an impellor, usually driven from above are excluded. !deleted text“ !1.3 This European Standard is not applicable
31、to food processors and blenders which are manufactured before the date of its publication as EN.“ BS EN 12852:2001+A1:2010EN 12852:2001+A1:2010 (E) 6 2 !Normative references The following referenced documents are indispensable for the application of this document.
