1 Scope This European Standard specifies safety and hygiene requirements for the design and manufacture of baguette slicers used in catering by adults, taking account of installation, cleaning, operating, maintenance and decommissioning. The intended use of these machines is to cut baguette and similar types of long bread sticks, into slices. This European Standard covers requirements for the safe operation of the machine including: loading, cutting, unloading, cleaning, crumb removal and maintenance. These machines have a crescent blade fixed to a shaft, with a rotating movement and vertical manual loading. These machines are intended to be installed on a table, a specific support or an integral stand. The following machines are excluded from the scope of this European Standard:  frame cutter machines with multiple blades1);  machines with rotary crescent (sickle) or circular blade fixed to a shaft with oscillating movement and horizontal manual loading1);  experimental and testing machines under development by the manufacturer;  domestic appliances. This European Standard deals with all significant hazards, hazardous situations and events relevant to baguette slicers, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). Noise is not considered to be a significant hazard. A noise test code is given in Annex A. This European Standard does not deal with noise reduction. This European Standard is not applicable to baguette slicers which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Hazards of cutting or severing. Zone 2: Access to cutting side of blade and other moving parts of the machine through discharge area and crumb tray.
Hazards of cutting or severing, drawing in and shearing. Zone 3: Access to all moving parts (e.g. drive mechanisms) through other sides of the machine.
Hazards of shearing, drawing in.

Figure 3 — Dimension of the cross-section of the chute opening 5.2.1.1.2 Safeguarding by distance If the distance between the edge of the infeed chute and the blade is < 850 mm, then the following requirements apply:  distance between the blade and the upper edge of the infeed chute shall be ≥ 550 mm (see Figure 5);  machine shall be supplied with an integral stand so that the distance from the floor to the upper edge of the infeed chute is ≥ 1 500 mm (see Figure 4). If the machine is not supplied with such integral stand, a permanent warning sign (see Figure 5) indicating the minimum height of the upper edge of the infeed chute (1 500 mm) shall be fixed to the machine and be clearly visible. In that case, the instruction handbook shall also state explicitly the required height of the upper edge of the infeed chute (see 7.1) The characters of the warning sign shall be at least 5 mm high and the sign shall be at least 40 mm high and 35 mm wide.

The value of 230 mm is measured from the actuating point at the interlocking system (see Figure 7); SIST EN 14655:2005
