Safety of Machinery - Safety requirements for cold flat rolling mills

This European Standard specifies the safety requirements for cold rolling mills for flat products (coiled or as heavy plates) as defined in 3.1.
This European Standard deals with significant hazards, hazardous situations and events relevant to cold rolling mills for flat products. It deals not only with circumstances where the machinery is used as intended, but also includes other conditions foreseen by the manufacturer, such as foreseeable faults, malfunctions or misuse (see clauses 4 and 5).
This European standard applies to: Machinery and equipment used for the manufacturing of metal cold rolled flat products from the material entry station (1), through the forming stations (2), to the exit (3) (see Figure 1).
The following equipment is outside the scope of this European Standard:
- furnaces in accordance with EN 746-1, EN 746-2 and EN 746-3;
- pickling plants according to EN 15061;
- strip processing lines according to EN 15061;
- abrasive blasting plants according to EN 1248;
- roll shop equipment;
- hook conveyors according to EN 619;
- storage equipment (e. g., high-bay warehouses);
- cranes, fork lifts, trucks and railway trucks and other vehicles.
This European Standard is not applicable to cold rolling mills for flat products, manufactured before the date of publication of this standard by CEN.

Diese Europäische Norm gilt für: Anlagen und Ausrüstung zur Herstellung von kaltgewalzten Flach¬erzeug-nissen aus Metall, vom Material-Einlaufteil (1) durch die Walzstationen (2) zum Auslauf (3) (siehe Bild 1).
Die folgende Ausrüstung ist vom Anwendungsbereich dieser Europäischen Norm ausgenommen:
   Öfen in Übereinstimmung mit EN 746-1, EN 746-2 und EN 746-3;
   Beizanlagen in Übereinstimmung mit EN 15061;
   Bandbehandlungsanlagen in Übereinstimmung mit EN 15061;
   Strahlanlagen in Übereinstimmung mit EN 1248;
   Ausrüstung der Walzenwerkstatt;
   Hakenbahnen in Übereinstimmung mit EN 619;
   Lagerausrüstung (z. B. Hochregallager);
   Krane, Gabelstapler, Transportwagen, Güterwagen und andere Fahrzeuge.
Diese Europäische Norm gilt nicht für Kaltflachwalzwerke, die vor dem Datum der Veröffentlichung dieser Norm durch das CEN hergestellt wurden.

Sécurité des machines - Prescriptions de sécurité relatives aux laminoirs à froid pour produits plats

La présente Norme européenne spécifie les prescriptions générales de sécurité pour les laminoirs à froid pour
produits plats (roulés ou tôles lourdes) comme défini en 3.1.
La présente Norme européenne traite des phénomènes dangereux significatifs, des situations et événements
dangereux associés aux laminoirs à froid pour produits plats. Elle ne prend pas seulement en compte les
conditions liées à l’utilisation normale de la machine mais elle inclut aussi d’autres conditions prévues par le
fabricant, comme les défauts, les dysfonctionnements ou le mauvais usage prévisible (voir Articles 4 et 5).
La présente Norme européenne s’applique aux : installations et équipements utilisés pour la fabrication de
produits métalliques plats laminés à froid depuis le poste d’alimentation en matière jusqu’à l’entrée (1) vers la
sortie (3) en passant par les postes de formage (2) (voir Figure 1).

EN 15094:2008 (E) 6 Foreword This document (EN 15094:2008) has been prepared by Technical Committee CEN/TC 322 “Equipment for making and shaping of metals”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by April 2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA and B, which is an integral part of this document. This European Standard has been elaborated by CEN/TC 322/WG 3, comprising experts from: Denmark, Germany, Italy, Sweden and the United Kingdom. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 15094:2008 (E) 7 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard. 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. Where for clarity an example of a preventative measure is given in the text, this should not be considered as the only possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent level of safety is achieved. This European Standard assumes that the equipment is operated and maintained by trained personnel.
