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, commissioning, 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.
