Where interlocking removable covers or lids are used, this interlocking shall be achieved according to 3.25.4 and 3.25.5 of EN ISO 12100-1:2003, 5.3.2.3 b) of EN ISO 12100-2:2003 and EN 1088:1995." For machines with hinged covers, the distance the cover may be opened whilst the machine is running, measured at the opposite side of the hinge, shall be no more than 45 mm. The stopping time shall be less than 4 s when the machine is running empty. 5.2.1.2.3 Type 3 Covers are generally hinged to the main body of the machine because of their weight. Some covers may be also removable to facilitate their use. !Covers shall be associated with an interlocking device in accordance with 3.25.4 and 3.25.5 of
EN ISO 12100-1:2003 and 5.3.2.3 b) of EN ISO 12100-2:2003." With non-removable covers, the interlocking device shall comply with 6.2.1 of EN 1088:1995. With completely removable covers, the interlock shall comply with EN 1088 (i.e. there shall be two interlock switches one operating in a positive mode and the other one in a negative mode). Where the application of this principle of positive mechanical action is not easily reconcilable with the other requirements for this kind of machine, e.g. hygiene, index of protection (IP), prevention of defeat and safety distances, the absence of a positive mechanical action of the cover on the position detector shall be balanced/compensated so as to achieve an equal level of safety e.g. by applying the principle illustrated in informative annex C. Nevertheless in all cases where a single mechanically actuated position detector is used, it shall comply with 6.2.1.2 of EN 1088:1995. !The safety distances from the upper edge of the aperture to the upper blade of the tool shall comply with
Table 4 and 4.2.4.3 of EN ISO 13857:2008." The stopping time shall be less than 4 s when the machine is running empty. If the bowl is removable, an interlocking device shall prevent the machine from starting with bowl incorrectly fitted. 5.2.1.3 Zone 3 !Access to the danger zone shall be prevented by a fixed guard complying with 5.3.2.2 of
EN ISO 12100-2:2003 and EN 953." Those requirements are applicable to the three types. 5.2.1.4 Zone 4 The bowl shall be tilted only by a voluntary action of the operator. The requirements shall be the same when the bowl is tilted back to its working position. When the tilting is power operated, the movement of the machine shall be controlled with a hold to run control situated out of the danger zone. The bowl shall remain stable in all positions when it stops. SIST EN 12852:2002+A1:2010
EN 12852:2001+A1:2010 (E) 16 5.2.1.5 Zone 5 The shape and fixing of the blades shall prevent accidental blade ejection. The connection between the cutter blades and their support shall be ensured by a positive mechanical means taking account of the direction, of centrifugal force. Relying on frictional connection alone is not sufficient. 5.2.2 Stability The machine shall be stable when used in accordance with the manufacturer's intended use. The machine shall be preferably designed to be stable and shall meet the tests specified in table 1 of clause 6. If the machine cannot comply with the tests of table 1, clause 6, it shall be fixed and the instruction handbook shall indicate the value of forces at fixing points. A machine fitted with 3 castors shall have at least 1 castor (or set of castors) fitted with a locking device. A machine fitted with 4 castors shall have at least 2 castors (or sets of castors) fitted with a locking device. 5.2.3 Incorrect assembly and fitting The design of the machine shall ensure that removable parts which provide safeguards in accordance with this standard are in the correct position before the machine can be set in motion. In addition, means of assembly and proper adjustment in good conditions shall be provided in the instruction handbook. If it can lead to a hazardous situation, incorrect assembly and fitting of the cutting device shall be prevented by design (e.g. by use of mechanically interlinked components). 5.2.4 Handling, cleaning and storage of cutting devices The manufacturer shall provide suitable instructions for the safe handling, cleaning and storage of the cutting devices. 5.3 !Electrical hazards 5.3.1 General Electrical equipment, for example switches, that may be exposed to water, e.g. during cleaning, shall be protected to an appropriate IP rating according to EN 60529 and EN 60204-1. The electrical equipment shall comply with EN 60204-1:2006 and with the requirements from 5.3.2 to 5.3.7. 5.3.2 Safety requirements related to electromagnetic phenomena The machines shall have sufficient immunity to electromagnetic disturbances to enable them to operate safely as intended and not fail to danger when exposed to the levels and types of disturbances intended by the manufacturer. The manufacturer of the machines shall design, install and wire the equipment and sub-assemblies taking into account the recommendations of the suppliers of these sub-assemblies. 5.3.3 Protection against electric shock The electrical equipment shall comply with Clause 6 of EN 60204-1:2006.
