1 Scope
This European Standard specifies requirements for the design and manufacturing of
circular saw machines (see Figures 1 and 2).
The machines covered by this European Standard are used to cut bone and meat.
The circular saw machines covered by this European Standard do not include circular
saw machines for processing of wood and similar materials and the requirements of
EN 1870‑1 do not apply.
Circular saw machines for domestic use are not included in this European Standard.
This European Standard applies only to machines which are manufactured after the date
of issue of this European Standard.
This European Standard covers the following types of machines:
Circular saw machines with a feed table and a fixed product pusher
-
— The distance "A" from the floor to the top surface of the feed table is from 800 mm to 1050 mm. The saw blade diameter is between 350 mm and 400 mm (see Figure 1).
-
— Circular saw machines installed in a cutting line (e.g. conveyor belt or roller conveyor), e.g. with a protective component which can be lifted on the feed and discharge side. The saw blade diameter is between 350 mm and 400 mm (see Figure 2).

Circular saw machines comprise a machine base, a fixed, foldable feed table, a product pusher, a protective hood which can be lifted, a saw blade, a drive and electrical components, depending on machine type.
Circular saw machines with a machine base can be wheel-mounted (see Figure 1).

This European Standard deals with all significant hazards, hazardous situations and
events relevant to circular saw machines, when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause
4).
This European Standard deals with the hazards which can arise during commissioning,
operation, cleaning, use, maintenance and decommissioning of the machine.
On floor-type circular saw machines (see Figure 3) the product to be cut is placed by hand onto the feed table and pushed against the cutting zone of the saw blade by means of the product pusher and sawed.
On circular saw machines which are installed in a cutting line (see Figure 4) the product to be cut is pushed by hand via the conveyor belt or roller conveyor
against the cutting zone of the saw blade and sawed.
