National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN
5、/TC 153 “Food processing machinery Safety and hygiene specifications” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-18-03 AA Aufschnittschneidemaschinen
6、of Section Nahrungsmittelmaschinen. Representatives of manufacturers and users of slicing machines, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Di
7、rective”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the
8、European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 and in the bibliography of the EN have been publis
9、hed as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to in this standard there are no national standards available unless they have been published as DIN ISO standards with the same number. Amendments This standard differs from DIN EN
10、 1974:1999-09 as follows: a) Normative references have been updated. b) In subclause 5.1.1, the interlocking devices shall now comply with EN 1088 and the control system with EN ISO 13849-1. c) In subclause 5.1.1, the requirements for fixed guards have been revised. d) In clause 7, information relat
11、ing to marking (7.4) and sound pressure level (7.2.1) has been revised. e) Annex ZB (informative) “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC” has been added.

DIN EN 1974:2010-05 EN 1974:1998+A1:2009 (E) 4 Introduction !This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situation
29、s 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 over the provisions of the other standards, for machines
30、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 formulated.“ 1 Scope 1.1 This European Standard specifi
31、es 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 types of slicing machines are intended to be used in sh
32、ops, 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 significant hazards at such machines, as identified by risk ass
33、essment (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 cleaning, dismantling of removable parts and changing the bl
34、ade. 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 significant hazards for these machines. 1.2 This Standar
35、d 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 blade guard, a blade sharpener, a gauge plate (a guard
36、 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, DIN EN 1974:2010-05 EN 1974:1998+A1:2009 (E) 5 Discharge conveyor. This Standard applies to machines which a
37、re 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 the application of this document.

44、ade 3.1.3 gravity feed slicer a slicer in which the product to be cut is fed to the blade by gravity. The product holder is inclined to the horizontal plane 3.1.4 blade guard a fixed annular ring mounted around the edge of that part of the blade which is not used for the cutting operation 3.1.5 blad
45、e cover a removable cover for the blade which covers the side of the blade adjacent to the carriage which is not used for the cutting operation 3.1.6 gauge plate a reference plate parallel to the blade against which the product is fed to the blade. The plate can be moved so that the desired thicknes
46、s of slice is achieved. 3.1.7 slice thickness control a control device by which the position of the gauge plate can be set in order to give the desired slice thickness 3.1.8 guard plate a plate similar to a gauge plate fitted to machines with automatic product feeding. It is approximately parallel t
47、o the blade and protects the space located between the blade and the extreme front of the stroke of the product holder. 3.1.9 blade sharpener a device equipped with suitable abrasive wheels used to sharpen the blade edge. It may be an integral part of the slicer or may be applied to the machine only
48、 during the sharpening operation. 3.1.10 product holder a support for the product to be sliced. Some different kinds of holder are used for sausages, ham, fresh meat etc. The product holder can be equipped with a pusher or a feed carriage and/or a clamping device. 3.1.11 carriage a support for the product holder which allows the longitudinal movement of the produc
