Food processing machinery - Baguette slicers - Safety and hygiene requirements
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.
