EN 12851:2005+A1:2010 (E) 4 Introduction The use of attachments involves various mechanical hazards and the attachments themselves need to meet food hygiene requirements. A catering attachment is a mechanical device which takes its motive power from a unit which is not part of the attachment. Some attachments are dedicated to a particular motive power source from the same manufacturers; others are designed to be used on a range of machines and power units from any manufacturer. !Their extensive use in numerous countries justifies 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 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and 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 according to the provisions of this type C standard.

EN 12851:2005+A1:2010 (E) 5 1 Scope 1.1 This European Standard specifies the safety and hygiene requirements for the design and manufacture of the following catering attachments intended to be connected to an auxiliary drive hub of machines used in catering (mainly but not exclusively planetary mixers) and to be used in the commercial and institutional catering industry: vegetable cutters and cheese graters; worm type attachments: fruit squeezers; meat mincers; pasta extruders; coffee grinder; strip cutters; planetary mixers and whippers; potato-mashers. 1.2 This European Standard deals with all significant hazards, hazardous situations and events relevant to catering attachments, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. It deals with the hazards due to the use, the maintenance, the cleaning, removal of jammed food, feeding and changing the tool (see Clause 4). 1.3 This European Standard is not applicable to: catering attachments which are exclusively part of the equipment of the machines they are intended for (as optional or standard equipment); the driving machines for which the attachments are intended (but the standard deals with the interface of the attachments with these machines); attachments including electrical equipment. 1.4 Noise is not dealt with in this European Standard. 1.5 This European Standard is not applicable to catering attachments which are manufactured before the date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the application of this document.

The main components of this part can be: 1) for vegetable cutting attachments and cheese grater (see Figure 1): a housing (5) into which a cutting device is inserted, the cutting device can be a blade (9) with or without a grid (3); a cover (4) incorporating the product feed device which is fixed to the housing; a feed device which may be a feed hopper (6) with pusher device (1) and/or plunger device (2); disc, cylinder or cone fitted with cutting/grating device of variable size (11) (the vegetable cutting attachment can be equipped with such tools), for cheese graters. Food product is loaded into the feed device and held against to the cutting device by manual pressure on the pusher or plunger. When the food is cut, it falls from the housing via the delivery chute (10) into a receptacle which is not part of the machine. SIST EN 12851:2006+A1:2010

In addition, the machine shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant, which are not dealt with by this document (e. g. sharp edges).’ NOTE For hazards which are to be reduced by the application of type B standard such as !EN ISO 13857", EN 614-1, EN 61310-1 and EN ISO 12100, the manufacturer should carry out a risk assessment to establish the requirements of the standard which are to be applied. This specific risk assessment is part of the general risk assessment of the machine. Where the means of reducing the risk is by the physical arrangement or positioning of the installed machine, the manufacturer shall include in the instruction handbook a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification. Where the means of reducing the risk is by a safe system of working the machinery, the manufacturer shall include in the instruction handbook details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 Vegetable cutters and cheese graters 5.2.1.1 Safeguards against access through feed chute and hopper Access to the cutting/grating tool through each of the feed chutes and hoppers shall be prevented or the risk of access reduced by one of the following measures: 5.2.1.1.1 Mechanical interlocking between the rotation of the tool and opening of devices which shall allow access to the tool (e. g. pusher devices) by a device integrated in the attachment (e. g. clutch system) for stopping the movement in case of opening of the feed hopper within 4 s. 5.2.1.1.2 A mechanically interlocked shutter plate which shall be brought in the position preventing the access to the blade at the base of the hopper, before the hinged pusher can be opened for permitting loading (see example in Figure 6). It shall only be possible to open the shutter plate for processing of the product when the pusher is again entering the hopper. SIST EN 12851:2006+A1:2010

A permanent sign shall be affixed to the attachment for reminding that the cutter depth shall not be higher than 8 mm; a cutter diameter (D) of maximum 230 mm; a feed inlet circumscribed diameter (d) of maximum 150 mm; the provision of a pusher device that descends by gravity for covering the feed inlet and that is shaped to the contours of the hoppers with a maximum clearance of 4 mm.

" Figure 8 — Safety signs 5.2.1.2 Safeguards against access to the danger zone by opening up of the cover The safety objective shall be to prevent access to the blade whilst it is still moving. This can be achieved by one of the following solutions: solution similar to 5.2.1.1.1; limiting the severity of the risk as set out in the firsts two indents of 5.2.1.1.3 and the following: either a tool shall be required for the cover removal;
or the design shall impose the operator to adopt a safe system at work and prevent impulsive opening of the cover, e. g. by requiring the use of both hands for the opening (see an example in Figure 9). The information for use shall include a warning about the dangers of removing the cover before the machine is at stand still. SIST EN 12851:2006+A1:2010

Figure 9 — Use of both hand for opening the cover 5.2.1.3 Measures against access through the discharge opening The risk shall be reduced by design. For rotating disc machines this could be achieved by contouring the underside of the cutter device or ejector plate such that the only contact would be with a smooth surface or one which would tend to deflect the fingers away from the area of the blade or other hazard (see Figure 10). The ejector shall have a radiused end to eliminate any trap between it and the machine casing. For cheese grater with cylindrical or conical grating device, the internal part shall be without sharp edges and the distance between the grating device and the housing shall be d ≤ 4 mm (see Figure 1b).
