Description of BS EN 13870:2005+A1:2010 2010

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 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.

1.2 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).

1.3 Machine construction

Chop cutting machines are constructed of a machine frame, a feed trough with an automatic forward feed device, a blade housing, a blade, a removal unit, associated drives, electrical, hydraulic and pneumatic components, depending on machine type.

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.

Although it should be advised against, the standard, taking into account practice, deals with the hazards due to cleaning with pressurised water.
