This document deals with all significant hazards, hazardous situations and events which are relevant to: - bridge sawing machines; - bridge sawing and milling machines; - numerical control bridge sawing/milling machines. These machines are designed to saw and mill natural stone and engineered/agglomerated stone as defined by EN 14618:2009, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This document deals with the foreseeable lifetime of the machinery including the phases of transport, assembly, dismantling, disabling and scrapping. This document also applies to machines fitted with the following facilities/devices: - mechanical, pneumatic, hydraulic or vacuum workpiece clamping; - automatic tool change; - loading and unloading conveyor system; - tilting and/or rotating head axis; - rotating workpiece support(s); - tilting workpiece support(s) when loading; - lathe unit; - undercut grooving unit; - axes operating in accordance with an NC work programme. This document does not apply to: - machines intended for operation in a potentially explosive atmosphere; - machines operating in severe environmental conditions (e.g. extreme temperatures, corrosive environment); - machines intended for outdoor operation; - machines which are manufactured before the date of their publication as EN.

This document applies to stationary surface-finishing machines with stationary work piece (see 3.1) or with moving work piece (see 3.2) which are used to grind or polish horizontal surfaces of slabs, strips or tiles of natural stone and engineered stone (e.g. agglomerated stone) as defined by EN 14618:2009. This document deals with all significant hazards, hazardous situations and events relevant to surface-finishing machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. This document deals with the foreseeable lifetime of the machinery including the phases of transport, assembly, dismantling, disabling and scrapping. This document does not deal with: - hand-held grinding machines; - machines intended for operation in a potentially explosive atmosphere; - operation in severe environmental conditions (e.g. extreme temperatures, corrosive environment); - machines intended for outdoor operation. This document is not applicable to machinery which is manufactured before the date of publication of this document by CEN.
