BS EN 1974:1998+A1:2009EN 1974:1998+A1:2009 (E) 4 Introduction !This document is a type C standard as stated in EN ISO 12100. The machinery concerne
24、d and the extent to which hazards, hazardous situations and hazardous 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 precedence ove
25、r the provisions of the other standards, for machines that have been designed and built to the provision of this type C standard. Complementary to the hygiene requirements common to all food processing machines, specific requirements for cleanability and sanitation of the machines in the scope are f
26、ormulated.“ 1 Scope 1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of slicing machines which are fitted with power driven circular cutting blade of more than 150 mm in diameter, with a reciprocating feed carriage and are transportable. These t
27、ypes of slicing machines are intended to be used in shops, restaurants, supermarkets, canteens etc. Industrial slicers are excluded. They are normally used in meat and sausage processing plants; they are not intended to be transportable and are permanently placed in position. It covers all significa
28、nt hazards at such machines, as identified by risk assessment (see EN 1050), which are listed in 4 of this Standard. It applies when such machines are operated under the intended use as defined in !3.22 and 5.2 of EN ISO 12100-1:2003“ and stated in the instruction handbook (see 7.2), included cleani
29、ng, dismantling of removable parts and changing the blade. NOTE If the machine is not used under the above conditions, the manufacturer should, when informed of such a situation, check by a new risk analysis that the preventative measures remain valid. Noise and vibration are not considered to be si
30、gnificant hazards for these machines. 1.2 This Standard covers the following types of slicing machines: Horizontal feed slicers (manual see figure 1 or automatic see figure 13 - ); Gravity feed slicers (manual see figure 2 or automatic). Slicing machines consist of a base, a blade, a blade cover, a
31、blade guard, a blade sharpener, a gauge plate (a guard plate for automatic slicers), a product holder, a reciprocating carriage, a product pusher and electrical control components. Slicing machines can be equipped with: Clamping device, Stacker, BS EN 1974:1998+A1:2009EN 1974:1998+A1:2009 (E) 5 Disc
32、harge conveyor. This Standard applies to machines which are manufactured after the date of issue of this Standard. !NOTE Nevertheless the manufacturers should minimise as much as possible noise and vibration emissions.“ 2 Normative references !The following referenced documents are indispensable for
