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.

This document stipulates the safety requirements for use of legs and rams as intended by the manufacturer or the manufacturer's authorized representative. These include legs, support rams and rams, including the mechanical extensions, the inner valves and safety devices, seals, the hydraulic connections, (up to the 1st hose line or to the valve of design B, see Part 3) and their lifting points but excluding protective pipes and gaiters, external valves and hydraulic and electrohydraulic control systems. NOTE Some components are discussed in other parts of this standard series. This document applies for legs, support rams, and cylinders that are used at ambient temperatures between –10 °C and 60 °C. This document identifies and takes account of: - possible hazards which may be caused by the operation of legs, support rams and rams; - the hazardous areas and the operating conditions that can cause any type of hazard; - the situations that can result in hazards that cause an injury or impair health; - dangers that can be caused through mine gas and/or flammable dusts. This document describes methods for reducing these hazards. Clause 4 contains a list of the hazards discussed. This document does not specify any additional requirements for: - specially corrosive environments; - risks associated with manufacturing, transport, and decommissioning; - earthquake. This standard is applicable to all legs, support rams and rams placed on the market for the first time and which are manufactured after the date on which this standard was published.

This document specifies the safety requirements for hydraulic and electro hydraulic control devices, including hydraulic valves and their control elements, valve combinations, control systems, pipes and hose assemblies, fittings, shut-off devices, measuring devices, filters, built-in pressure limiting and check valves in legs and rams and water spraying and dust suppression valves, as well emergency stop, start warning, locking- and control unit when used as specified by the manufacturer or his authorized representative. Excluded are pressure generators, and internal valves of legs and rams (e.g. leg bottom valves, see EN 1804-2). NOTE Some components are dealt with in other parts of this standard. This document applies to hydraulic and electro hydraulic control devices at ambient temperatures from -10 °C to 60 °C. This document identifies and takes into account: - possible hazards which may be caused by the operation of hydraulic and electro hydraulic control devices; - areas and operating conditions which may create such hazards; - hazardous situations which may cause injury or may be damaging to health; - hazards which may be caused by firedamp and/or combustible dusts. This document describes methods for the reduction of these hazards. A list of significant hazards covered appears in Clause 4. This document does not specify any additional requirements for: - use in particularly corrosive environments; - hazards occurring during construction, transportation, decommissioning; - earthquakes. This document is applicable to all hydraulic and electro hydraulic control unit placed on the market for the first time and which are manufactured after the date on which this standard was published.

This document stipulates the safety requirements for the use of support units intended by the manufacturer or the manufacturer's authorized representative. Examples of support units are: frame supports, chock supports, shield supports, paired frames and push-pull support systems including the components of advancing and anchoring devices which provide support functions. This document excludes fixing elements on the conveyor, coal-winning equipment, power set legs and rams, valves, hydraulic and electro-hydraulic control units, lighting and signalling facilities and other ancillary equipment. COMMENT Some components are discussed in other parts of this series of standards. This document applies for support units that are used at ambient temperatures between -10 °C and 60 °C. This document also applies to support components and support accessories which are provided if the support unit is fitted with stowing equipment. This document identifies and takes account of: - the hazards that can possibly be induced through operation of the support units; - the hazardous areas and the operating conditions that can cause any type of hazard; - the situations that can result in hazards that cause an injury or impair health; - dangers that can be caused through mine gas and/or flammable dusts. This document describes methods for reducing these hazards. Clause 4 contains a list of the hazards discussed. This document does not specify any additional requirements for: - a particularly corrosive environment; - risks associated with manufacturing, transport and decommissioning; - earthquake. This document applies for all support units that have been placed on the market for the first time after the issue date of this standard.
