The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this document. When pr
26、ovisions 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
27、. BS EN 12331:2015EN 12331:2015 (E) 6 1 Scope 1.1 This European Standard specifies requirements for the design and manufacture of mincing machines (see Figures 1a and 1b) used in a stationary position. The machines covered by this European Standard are used for size reduction of fresh or frozen meat
28、, meat products and fish (hereinafter referred to as product) by cutting in a set of cutting tools. Mincing machines for domestic uses are not included in this European Standard. Filling mincers are covered by EN 12463 “Food processing machinery Filling machines and auxiliary machines Safety and hyg
29、iene requirements”. This European Standard applies only to machines that are manufactured after the date of issue of this European Standard. Mincing machines in connection with using a hold-to-run foot switch are not covered by this European Standard. This European Standard covers: mincing machines
30、used in shops and preparation rooms; mincing machines used in kitchens where sausages are prepared; mincing machines used industrially; accessories. The extent to which hazards are covered, is indicated in this European Standard. For other hazards which are not covered by this European Standard, mac
31、hinery should comply with EN ISO 12100:2010 where applicable. This European Standard is not dealing with specific requirements for the control of mincing machines with foot switch. 1.2 This European Standard covers the following types: mincing machine with feed tray, feed intake and pusher, diameter
32、 52 mm on feed intake (see Figure 3); mincing machine with feed tray, feed intake, restrictor plate and pusher, diameter 52 mm on feed intake (see Figure 4); mincing machine with feed intake hopper and cover, screw conveyor, with 1)or without mixing screw in feed intake hopper (see Figure 5); mincin
33、g machine with feed intake hopper, with or without cover, screw conveyor, with1)or without mixing screw in the feed intake hopper, with loading device (continuously or discontinuously). Mincing machines comprise a machine base, a worm casing with a worm, a feed tray (with feed intake) or a feed inta
34、ke hopper, a screw conveyor (and sometimes an additional mixing screw in the feed intake hopper), a set of cutting tools, a lock nut, a loading device, a drive motor and depending on machine type electrical, hydraulic and pneumatic components. They will also have various safeguarding devices as exam
35、ples in Clause 5. 1) In this case, EN 13570 should be taken into consideration.

37、extraction claw, an ejector or extractor, a protective hood over the discharge outlet, a cover over the inlet opening of the feed intake hopper, a transport carriage for the lock nut, the set of cutting tools, the worm and the screw conveyor, a lifting device for the lock nut, the set of cutting too
38、ls, the worm and the screw conveyor, a loading device. 1.3 Intended use The product is fed manually or by means of the loading device into the mincing machine. The product is fed to the worm either by means of a pusher or a screw conveyor and size reduced in the set of cutting tools. It is not inten
39、ded that mincing machines are cleaned with pressurized water. However, it is to be foreseen that it is difficult to guarantee that this method will never be used in practice. In order to deal with this eventuality, the requirements of 5.3.4 should apply. BS EN 12331:2015EN 12331:2015 (E) 8 This Euro
40、pean Standard specifies all significant hazards, hazardous situations and events relevant to mincing machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the hazards which can ari
41、se during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
