Introduction
This document 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 document.
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 to diamond wire saws being used in quarries as well as in processing plants
for cutting marble, granite and other stones out of a mass of rocks in a quarry or of blocks having been al-
ready extracted. The machines can be either stationary or travelling on rails during operation.
Diamond wire saws in the scope have an electric main motor. This standard deals with machines working in
one main axis as well as in several axes. Furthermore, this standard does not deal with problems caused by
an irregular structure of the stones to be cut.
Diamond wire saws are intended to be used with diamond cutting wires also referred to as tools in this stan-
dard.
For transportable machines, this standard deals only with machines using coated wire tools.
This standard deals with all significant hazards, hazardous situations and events relevant to diamond wire
saws, 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 during transport, commis-
sioning, use and maintenance.
This standard does not deal with noise as a significant hazard.
This European Standard does not deal with:
 operation under extreme ambient conditions (outside the limits defined in EN 60204-1);
 upstream and downstream conveying elements for transporting the work-pieces.
This document is not applicable to machines which are manufactured before the date of its publication as EN.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100-1 and the following apply.
3.1
diamond wire saw
machinery for cutting marble, granite and other natural stones from stone deposits or already extracted stone
into blocks and slabs using a suitable diamond wire as tool. During the cutting operation, the tool can be
cooled by water. In that case, the water also serves for the suppression of dust emission during the cutting
operation.
The diamond wire saws in the scope have an electric motor as main drive.
Different types of diamond wire saws:
 transportable diamond wire saws (mining of natural stone) (see Figure 1);
 travelling diamond wire saws (see Figure 2);
 stationary diamond wire saws with block trolley (see Figure 3);
 stationary diamond wire saws without block trolley (Figure 4);
 diamond wire saws for contour (two and more axes) (see Figure 5);
 multi-wire saws (see Figure 6).
