Introduction of safety rule IEC EN62061 in Metal Industry

Safety in industrial plants is one of the main topics of the decade and this is reflected in the related rules proliferation. The well known safety rule EN954-1 [2] is going to be retired in December 2011. Two different rules have been introduced, the ISO EN 13849 [3] and IEC EN 62061 [5]. The two rules are not so easy to read and to apply because they introduce some statistical parameters that are not usual for system designers. The aim of this paper is to introduce an example of application of the IEC EN62061 and to identify if the same safety approaches that came from the application of the old EN 954-1 rule are still valid.
