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 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 over 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 formulated." 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 types 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 significant 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 cleaning, 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 significant 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 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.

Fixing systems of fixed guards shall remain attached to these parts or to the machine when the parts are removed." 5.1.2 Blade protection 5.1.2.1 The blade shall be provided with suitable protection which covers all the cutting edge of the blade which is not necessarily exposed to enable the product to be cut. 5.1.2.2 Blade protection consists of: a) A blade guard, b) A gauge plate or a guard plate, c) A product holder, d) A blade sharpener (if integrated) And may also include on some machines a blade cover and a blade removing device. 5.1.2.3 The blade guard shall project at least 1 mm from the cutting edge of the blade (see figures 3 and 4). When a force of 50 N is applied from any position to the blade guard the guard shall not be deflected to such an extent that the blade guard projects less than 1 mm from the cutting edge of the blade. The blade guard shall be non-removable (see figures 3 and 4). 5.1.2.4 If no blade cover is fitted (as shown in figure 3) the gap between the blade guard and the cutting edge of the blade shall not exceed 6 mm. When a blade cover is fitted without interlocking device as shown in figure 4 b, the gap between the guard blade and the cutting edge of the blade shall not exceed 6 mm. When a blade cover is fitted as shown in figure 4a, the gap between the blade guard and the cutting edge of the blade shall not exceed 12 mm and the blade cover shall be interlocked with the motor driving the blade so that the motor cannot run when the cover is removed. 5.1.2.5 The gauge plate in the zero position shall be overlapped by the blade guard at the upper and lower edges for at least 10 mm. The gap between the gauge plate and the blade shall not exceed 6 mm when the gauge plate is in the zero position (see figure 5). The machine shall not be capable of cutting slices more than 40 mm thick. 5.1.2.6 When the slice thickness control is set to zero the gauge plate shall overlap the cutting edge of the blade by at least 1 mm in order to give protection to the part of the blade used for cutting. When a force of 50N is applied from any position to the gauge plate when the slice thickness control is set to zero, the gauge plate shall not be deflected to such an extent that the cutting edge of the blade is covered for less than 1 mm (see figure 6). In the bottom area the blade guard shall be designed in a way, that the distance to the slice support is not more than 6 mm (see figure 6). 5.1.2.7 The machines may be equipped with a slice support (see figure 6) which acts as a part of the blade guard. The slice support can be adjustable and shall satisfy the same overlapping criteria as in 5.1.2.3 and 5.1.2.6 above. SIST EN 1974:2000+A1:2010
EN 1974:1998+A1:2009 (E) 11 5.1.2.8 The segment of unprotected blade used for slicing shall be no more than 60û above the horizontal centre line of the blade (see figure 6). 5.1.2.9 The gauge plate and slice support shall be fixed to the machine in such a way that they cannot be removed from the machine without the use of tools. 5.1.3 Requirements for blade sharpeners 5.1.3.1 The construction of the blade sharpener shall not allow the blade to be sharpened any longer when the gap between the blade and the blade guard exceeds 12 mm in the case of machines fitted with a blade cover as shown in figure 4a, and, in any other case, when the gap exceeds 6 mm (see figure 8b). 5.1.3.2 Blade sharpener integral with the machine 5.1.3.2.1 The blade sharpener shall be made in such a way that during the normal use of the machine it ensures a continuous cover over the blade in the same manner as the blade guard or the blade cover. 5.1.3.2.2 In the sharpening position that part of the blade which is exposed shall not exceed a distance of 6 mm on each side of the abrasive wheels used for grinding (see figure 7). 5.1.3.2.3 When the blade sharpener has been removed (e.g. for servicing), the residual risk of the exposed part of the blade shall be mentioned in the instruction handbook. 5.1.3.3 Separate blade sharpener 5.1.3.3.1 The blade sharpener shall, when fixed to the gauge plate or to the product holder, have attached to it a suitable guard to cover all the part of the blade adjacent to the product holder normally used for slicing the product. Any gap between the abrasive wheels used for grinding and any fixed guard shall not exceed 6 mm (see figure 8a). 5.1.3.3.2 The blade sharpener shall be suitably marked to indicate the machine with which it is to be used. The Instruction Manual shall state that a blade sharpener shall only be used with the machine for which it was provided. 5.1.4 Product holder 5.1.4.1 The product holder shall be equipped with a thumb guard so that it covers all parts of the blade not otherwise protected. When the carriage is at the backward stroke, the cutting edge of the blade shall be covered completely by the thumb guard and shall overlap at least 10 mm. The gap between the thumb guard and the cutting edge shall not exceed 6 mm (see figure 6). 5.1.4.2 The finger guard shall be fixed to the product holder and shall be non-removable. The height of the finger guard shall be the same as the height of the cutting part of the blade and extend at least 150 mm from the blade (see figures 1 and 2). The radius at the corner of the finger guard shall not exceed 30 mm. 5.1.4.3 It shall not be possible to remove or to lift the product holder unless the gauge plate or guard plate is in the zero position. It shall not be possible to adjust the gauge plate or guard plate when the product holder has been removed or lifted from the carriage. 5.1.5 Additional requirements depending on the configuration of the slicer 5.1.5.1 Product holder with clamping device SIST EN 1974:2000+A1:2010

When no such guards are fitted the edge of the handle on the carriage of the machine shall be at least 80 mm from the plane of the blade. The handle shall also be fitted with a plate which extends at least 30 mm from the handle to ensure that a thumb cannot reach the blade (see figure 9).
