Introduction
This European Standard is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards for machines
that have been designed and built according to the provisions of this type C standard.
1 Scope
This European Standard applies for stationary and on a rail system moveable circular block saws, consecu-
tively called machines, designed to saw natural stone blocks, as e.g. granite and other natural stone-like ma-
terials.
This European Standard deals with all significant hazards, hazardous situations and events relevant to circular
block saws, when they are used as intended and under conditions of misuse which are reasonably foresee-
able by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical meas-
ures to eliminate or reduce risks which can arise from these significant hazards.
This European Standard does not deal with:
 machines which are intended for operation in a potentially explosive atmosphere;
 upstream and downstream conveying elements for transporting the workpieces.
This European Standard does not deal with the following:
 operation in severe environmental conditions (e. g. extreme temperatures, corrosive environment);
 supply by electrical networks with voltages, frequencies, tolerances, etc different from those of public
suppliers;
 hazards due to errors in the software;
 cordless remote controls.
This European Standard does not cover machine operation in environments where electromagnetic distur-
bances are outside the range of those specified in EN 50082-2.
This European Standard does not deal with significant hazards associated with noise.
This European Standard is not applicable to machinery which are manufactured before the date of publication
of this document by CEN.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1 apply.
3.1
circular block saw
circular block saws are machines mounted on a base or alternatively movable on a track system, which are
operated on a certain place and mainly used to cut natural stone blocks
 with a stationary block circular saw, the infeed results from a horizontal support at the bridge which is
fixed on a basement, while the adjustment of the workpiece is done by means of a stone block trolley;
 with a movable block circular saw, the infeed results from a horizontal support at the bridge which can be
adjusted to different saw positions by means of running gears and a track system. The work piece is sta-
tionary;
 the main drive of a block circular saw results from an electric motor
3.2
types of circular block saws
block circular saws which are classified in three types characterised below:
 type 1: machine with stationary bridge and movable support with cutting-off wheel. The adjustment of
the workpiece is done by means of a block trolley;
 type 2: machine with adjustable bridge, movable support with cutting-off wheel and stationary work-
piece;
 type 3: combination from Type 1 and Type 2, where e. g. the infeed results from a movable block trolley
whereas the bridge is stationary
