Food processing machinery - Chop cutting machines - Safety and hygiene requirements
This document covers chop cutting machines and accessories. The extent, to which hazards are covered, is indicated in this document. This document specifies requirements for design and manufacture of chop cutting machines. The machines covered by this document are used for continuous portioning of fresh, smoked or frozen meat with and without bones or of similar products by separation by means of a blade. This document deals with all significant hazards, hazardous situations and events relevant to machines, appliances and machinery, when they are used !as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4)". This document deals with the hazards which can arise during commissioning, operation, maintenance and decommissioning of the machine. The document is not dealing with the specific hazards of loading devices. This document is not applicable to chop cutting machines which are manufactured before the date of publication of this document by CEN.

1 Scope This document covers chop cutting machines and accessories. The extent, to which hazards are covered, is indicated in this document. 1.1 This document specifies requirements for design and manufacture of chop cutting machines. The machines covered by this document are used for continuous portioning of fresh, smoked or frozen meat with and without bones or of similar products by separation by means of a blade. This document deals with all significant hazards, hazardous situations and events relevant to machines, appliances and machinery, when they are used !as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4)". This document deals with the hazards which can arise during commissioning, operation, maintenance and de-commissioning of the machine. The document is not dealing with the specific hazards of loading devices. This document is not applicable to chop cutting machines which are manufactured before the date of publication of this document by CEN. 1.2 This document covers the following types of machines: chop cutting machines with a discharge chute (Figure 1); chop cutting machines with a discharge trough (Figure 2).

Chop cutting machines in the scope of this document may be equipped with: a feed conveyor belt in longitudinal- and lateral axis; a removal conveyor belt; a transfer trolley for the blade. 1.4 Intended use The intended use (as defined in EN 12100-1:2003, 3.22) of chop cutting machines as dealt with in this document is described in 1.1. The material to be cut is fed either manually or by means of a loading device into the feed trough. The material to be cut is fed to the blade by means of the automatic forward feed device. The product falls via the discharge chute into a trolley or into a discharge trough which may be equipped with a removal conveyor belt. SIST EN 13870:2005+A1:2010

In addition, they 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). !For hazards which are to be reduced by the application of the type B-standards such as EN 614-1, EN 953, EN 1005-3, EN 1088, EN 1672-2, EN 60204-1, EN 60529, EN ISO 12100, EN ISO 13849-1 and
EN ISO 13857, the manufacturer shall carry out a risk assessment to establish the requirements of the type
B-standard. This specific risk assessment shall be 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 machine the manufacturer shall include in the Information for use a reference to these means, 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 work, the manufacturer shall include in the Information for use details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 General Chop cutting machines shall be designed and constructed in accordance with Annex C and the conditions mentioned below. SIST EN 13870:2005+A1:2010
EN 13870:2005+A1:2010 (E) 17 The guards shall comply with EN 953. !Unless otherwise stipulated in other sub-clauses, the interlocking systems of guards shall comply with 4.2.1 of EN 1088:1995 (interlocking without guard locking) and the safety related components of the control system shall present at least a performance level “c” of EN ISO 13849-1:2008." The interlocking devices shall be incorporated in the machine housing and correspond to 5.7 of EN 1088:1995. NOTE This is required to: fulfil hygienic requirements; protect against mechanical damages; protect against the effects of cleaning and disinfecting materials; protect against the effects of cleaning fluids (water); protect against tampering by simple methods. !Fixing systems for fixed guards or for demountable parts of the machine casing (i.e. designed as fixed guards) shall remain attached to the guards or to the machine when the guards are removed." 5.2.2 Measures on Chop cutting machines with discharge chute Zone 1 Access between returning forward feed device, drive mechanism and housing As far as crushing hazards cannot be eliminated by design, the access shall be prevented by guarding. Taking into account the specific technical constraints (high loading frequencies), the guard(cover), if movable, can be designed as a control guard according to !EN ISO 12100-1:2003, 3.25.6". If it is necessary to dismantle guards frequently for changing the process or for cleaning, they shall be movable and interlocked. Zone 2 Access to the blade in cutting area of feed trough Access into the danger zones in the cutting area shall be prevented by a cover over the feed trough (see 5.2). Movable guards shall be interlocked with dangerous movements. For requirements relating to the interlocking system of the cover with the sickle blade drive, see 5.2.4. The movable cover may also be designed as a control guard according to !EN 12100-2:2003, 3.25.6". Neverthel
