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. It is intended to revise this standard to align with changes in legislation and the availability of other European Standards in preparation. SIST EN 15027:2008

1 Scope The global description “wall saw and wire saw equipment” contains two differing types of machines for use in the construction industry, and both used to make cuts on walls, ceilings and floors composed of mineral construction materials and/or composite materials. The many different cutting tasks and choice of operating method determine the type of machine to be used for each application. The machines may therefore be split into the following two principal classifications:  Wall saws – exclusively rail guided – transportable.  Wire saws – transportable. The machines are intended for the use of diamond tools. The types of cutting tools used in conjunction with the machines as described above fall within the design and use parameters supplied by the manufacturer. Cutting debry generated by the cutting action is removed from the cutting joint by a medium such as water directed to the cutting tool. Machines covered by this standard may be powered by: electric motor, IC engine, electro-hydraulic drive and IC engine-hydraulic drive. This European Standard deals with all significant hazards, hazardous situations and events relevant to wall saws and wire saws machinery, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards generated by the cutting process work cycle. For special applications, for example, when working in potentially explosive atmospheres, additional safety requirements is necessary which are not covered by this standard.
This European Standard does not apply for wire saws intended for quarrying and stationary machining of natural stone as covered by prEN 15163. This European Standard applies primarily to machines which are manufactured after the date of approval by CEN of this standard. 2 Normative references The following referenced documents are indispensable for the application of this document.

5.2 Mechanical hazards 5.2.1 General As components and parts have to be manually handled, all accessible parts, the cutting tool excepted, shall be free of sharp edges and burrs which could generate hazards when setting up, using, handling and maintaining the machine. Burrs from, for example, manufacturing, casting and welding shall be eliminated, sharp edges shall be smoothed. 5.2.2 Protection against moving parts 5.2.2.1 Moving parts not involved in the working process Rotating transmission parts, for example, couplings and drive shafts shall be provided with fixed guards to prevent contact. Guards shall comply with EN 953:1997 and in particular with Clauses 5, 6 and 7. Fixed guards shall be used and be held in position either by welding or mounting them in such a way that they can only be opened or removed only with the aid of tools or keys. Guards shall comply with the provisions of EN 294:1992 on safety distances. When daily access is required for service or maintenance purposes instead of fixed guards, movable guards (see EN ISO 12100-2:2003, 5.3.2.3 a), may be fitted. They shall fulfil the following requirements:  they shall remain fixed to the machine when open;  they shall be fitted with a system holding them in the open position. NOTE The system may be of – for example – a locking, latching, own-weight or spring loaded type. 5.2.2.2 Moving parts involved in the working process 5.2.2.2.1 General
The guards for the protection against contact with the tool and its driving and guiding devices shall be so designed and robust enough to resist strains resulting from an accidental projection of fragments of the cutting tool. Brittleness of the guard material shall be taken into account. Permanent plastic deformation of the guard resulting from stress shall be allowed. Requirements for the strength of cutting-off wheel and wire guards are specified in Annex B. The existence of a device stopping the cutting-off wheel is not necessary, when the absence or the opening of the guard creates a projection of water, which prevents an intended use of the machine. SIST EN 15027:2008

Only for flush cutting the guard may have a open side (lateral) or a special design in order to allow a cut close to adjacent surface (see operator's instructions in 7.3.2.3). In that case fixing screws and similar devices shall be designed countersunk in the flange or cutting tool. 5.2.2.2.3 Wire saws The drive, tensioning (feed) and storage system of the wire saw except of the external wire guiding devices shall be covered with fixed guards to avoid inadvertent contact. This/these guard(s) shall have sufficient strength to protect against ejection of fragments of the tool. When designing the guard system it shall take into account that the machine will be remotely controlled by the operator. The distance from the unprotected moving tool to the remote control shall allow that the operator can operate the machine outside the dangerous area described in the instruction manual (see 7.3.2.3).
The mounting and dismounting of the guard system shall need an intentional manual action. For removable guard systems, keyless fixation of the guard may be applied as an alternative to a key operated system. 5.2.3 Stability The machines shall be designed and constructed so that they are sufficiently stable under the intended operating conditions. Machines shall be equipped with fixing devices which shall allow a rigid and safe mounting in relation to the material to be cut. Nuts and screws intended to adjust the mountings in position shall need intentional action to loosen. 5.2.4 Transport and handling The movable parts of the machine shall be either lockable or removable to avoid risk of shearing, crushing, unlocking or falling down e. g. during handling or carrying. NOTE For technical requirements relating to transport and lifting of machines see 5.5.5 of EN ISO 12100-2:2003, Annex A.
