Machine tools - Safety - Sawing machines for cold metal
1.1 This standard specifies the safety requirements and measures to be adopted by persons undertaking the design, construction and supply (including installation, setting–up, maintenance, and repair) of machines whose primary intended use is for sawing cold metal (ferrous and non-ferrous), or material partly of cold metal, by means of a saw blade.
1.2 This standard takes into account the intended use, reasonably foreseeable misuse, machine setting and blade fitting, maintenance and cleaning, and their effects on the safety of operators and other exposed persons. It presumes access to the machine from all directions at floor level and addresses both normal operation and unexpected or unintended starting.
1.3 This standard applies to the ancillary devices which form an integral part of the machine. Where such devices are not an integral part of the machine, the designer, manufacturer or supplier of the installation should take into account their intended use, and should make provision for the safe linking of such devices with the machine.
1.4 This standard applies to (metal) sawing machines which are manufactured after the date of publication by CEN of this standard.

1.1 La présente norme précise les !prescriptions" de sécurité et les mesures qui doivent être prises par les personnes réalisant la conception, la construction et la fourniture (y compris l’installation, le montage, la maintenance et la réparation) des machines, destinées principalement au sciage des métaux à froid (ferreux et non-ferreux) ou des matériaux constitués partiellement de métaux à froid, au moyen d’une lame de scie.
1.2 La présente norme tient compte de l’utilisation normale, du mauvais usage raisonnablement prévisible, du réglage des machines et de la fixation de la lame, de l’entretien et du nettoyage, ainsi que de leurs effets sur la sécurité des opérateurs et des autres personnes exposées. Elle présume de l’accès à la machine dans toutes les directions au niveau du sol et traite à la fois du fonctionnement normal et d’une mise en marche inattendue ou intempestive.
1.3 La présente norme s’applique aux dispositifs auxiliaires qui font partie intégrante de la machine. Lorsque ces dispositifs ne font pas partie intégrante de la machine, il convient que le concepteur, le fabricant ou le fournisseur de l’installation tiennent compte de leur utilisation normale, et prévoient la liaison en toute sécurité de ces dispositifs avec la machine.
1.4 La présente norme s’applique aux machines à scier (les métaux) fabriquées après la date de publication de la présente norme par le CEN.
Obdelovalni stroji - Varnost - Žage za hladne kovine
Ta standard določa varnostne zahteve in ukrepe, ki jih morajo uporabljati osebe, ki se ukvarjajo z načrtovanjem, gradnjo in dobavo (vključno z namestitvijo, postavitvijo, vzdrževanjem in popravilom) strojev, katerih primarni namen uporabe je žaganje hladnih kovin (železove skupine in barvne), ali materiala delno iz hladne kovine, z uporabo rezila žage. Ta standard upošteva nameravano uporabo, razumno predvidljivo napačno uporabo, nastavitev stroja in montažo rezila, vzdrževanje in čiščenje, njihov učinek na varnost upravljavcev in drugih izpostavljenih oseb. Predpostavlja dostop do stroja z vseh strani na ravni tal in obravnava tako normalno delovanje kot nepredviden ali nenameravan zagon. Ta standard se uporablja za pomožne naprave, ki predstavljajo sestavni del stroja. Kjer takšne naprave niso sestavni del stroja, mora načrtovalec, izdelovalec ali dobavitelj celotne naprave upoštevati njihov namen uporabe in mora zagotoviti, da so takšne naprave varno povezane s strojem. Ta standard se uporablja za (kovinske) stroje za žaganje, ki so bili izdelani po datumu, ko je CEN objavil ta standard.

- saw blade retraction
- unclamp work material 3.6 automatic machine machine in which the power-operated elements perform continuous or repeat cycles, the first cycle initiated by a control system start from the operator until either an automatically-determined condition is achieved, or a stop signal is given by the operator NOTE A typical cycle can be:
-
feeding of work material
- clamping of work material
- feeding of saw blade through work material
- saw blade retraction
- unclamping of work piece
- unloading of work piece
- unclamping of work material
- repeat above cycle until stop signal 3.7 back jaw feed (hitch feed) power-operated work material feeding device having a carriage-mounted vice which grips the work material at any point along its length and traverses it to the sawing position, the required work material length is determined by the stroke of the feed carriage 3.8 push feed power-operated work material feeding device pushing on the tail end of the work material to advance it to a position or length stop which determines the required work material length 3.9 roller feed power-operated work material feeding device in which the work material is fed by a roller or rollers, such devices can incorporate work piece gripping and length measuring systems 3.10
Kinds of sawing processes 3.10.1 profile and contour cutting work material is pushed either by hand or under power through the saw blade, following a path which is not parallel to the plane of the saw blade, profile and contour cutting uses a vertical band-sawing machine, fixed saw frame, contour cutting type 3.10.2 mitre-sawing work material is cut out of square to the longitudinal axis 3.11 work area danger zone through which the saw blade traverses to process the work material and includes the work material holding mechanism (where applicable) 3.12

The safety requirements and/or protective measures and information for use contained in clauses 5 and 7 are based on the risk assessment and deal with the identified hazards by either eliminating them or reducing the effects of the risks they generate. 4.2 The risk assessment assumes foreseeable access from all directions, as well as unexpected start–up. Risks to both the operators and other persons who can have access to the hazard zones are identified, taking into account hazards which can occur under various conditions (e.g. commissioning, set–up, production, maintenance, repair, decommissioning) during the life of the machine. The assessment includes an analysis of the effect of failure in the control system. 4.3
In addition, the user of this standard (i.e. the designer, manufacturer, supplier) shall validate that the risk assessment is complete for the machine under consideration with particular attention to: the intended use of the machine including maintenance, setting and cleaning, and its reasonably foreseeable misuse; the identification of the significant hazards associated with the machine.
