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 standar
28、d 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 ma-chines that have been designed and built according to the provisions of this type C standard.

29、008 (E) 6 1 Scope This standard applies to monoblade or multiblade gang saws, as defined in 3.1, for cutting marble, granite, other types of natural stone, artificial or natural conglomerates and similar materials. This standard does not deal with noise as a significant hazard. This standard deals w
30、ith all significant hazards, hazardous situations and events relevant to gang saw ma-chines, 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-sioni
31、ng, use and maintenance. This document is not applicable to gang saws which are manufactured before the date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the application of this document.

42、 machines for cutting of marble, granite, other types of natural stone, artificial and natural conglomerates as well as similar materials, hereafter referred to as gang saws, are classified according to the material to be cut and the number of blades. A further classification is based on the technol
43、ogy used to position the block in rela-tion to the blades which may be done by a fixed carriage with the descent of the blades or a mobile rising car-riage with blades at fixed height. Following these principles, the machines in the scope are classified and described in 3.1.1 to 3.1.3 3.1.1 granite
44、and hard stone gang saw (see Figure 1) machine for cutting blocks of granite or hard stones into slabs. The machine consists of 4 upright columns connected to one another which support a vertically and horizon-tally moving blade-carrying structure. This structure moves vertically (descent movement)
45、by a screw system positioned in the columns and horizontally by a system composed of a flywheel connected by a rod with the blade-carrying structure. While operating both directions together, the structure creates a swinging movement of the blade carriage. A mobile railed carriage moves the granite
46、block into position under the blade carriage. A system of pipes with nozzles above the blades provides a mixture of water, lime and abrasive steel shot which acts as the cutting tool between the blade and the granite block and additionally ensures the cooling of the blades DIN EN 15162:2008-10 EN 15

This structure moves vertically (descent movement) by a screw system positioned in the columns and horizontally by a system composed of a flywheel connected by a rod with the blade-carrying structure. While operating both directions
49、together, the structure creates a rectilinear move-ment of the blade carriage (see Figure 2). In some machines, the vertical movement is carried out by raising the block and keeping the blade carriage at a set height (see Figure 3). A mobile railed carriage moves the block into position under the blade carriage. The cutting of the stone is performed by the diamond bits of the blades. A system of pipes with nozzles above ensures the cooling of the blades Figure 2 Marbl
