Ta evropski standard obravnava pomembne nevarnosti, nevarne situacije in dogodke v zvezi z vročimi valjarnami za dolge izdelke. Ukvarja se z okoliščinami, v katerih se stroji namensko uporabljajo, ter tudi z drugimi pogoji, ki jih je predvidel proizvajalec, kot so predvidene okvare, napake ali nepravilna uporaba.
Ta evropski standard se uporablja za: stroje in opremo, ki se uporablja za izdelovanje kovinskih valjanih dolgih izdelkov od dovoda materialov, prek valjarniških stojal do izhoda, skupaj z območjem za pripravo.
Izključena je naslednja oprema:
– peči v skladu s skupino EN 746;
– stroji za zvezno litje jekla v skladu s standardom EN 14753;
– tekoči trakovi s kljukami v skladu s standardom EN 619;
– vrtljiva oprema za obrate;

EN 15949:2012 (E) 5 Foreword This document (EN 15949:2012) has been prepared by Technical Committee CEN/TC 322 “Equipment for making and shaping of metals - Safety requirements”, 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of an identical text or by endorsement, at the latest by August 2012, and conflicting national standards shall be withdrawn at the latest by August 2012. 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 EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. 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, Croatia, 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, Turkey and the United Kingdom.

EN 15949:2012 (E) 6 Introduction This document is a type C standard as stated in EN ISO 12100:2010. The equipment 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. SIST EN 15949:2012
