The European Commission has reconsidered the Machinery Directive Working Group's (MDWG's) decision to grant a three-year extension for the current safety standard EN 954-1 beyond December 29 2009. A final decision on whether or not the presumption of conformity of EN 954-1 will be extended past this date will now be taken after the MDWG meets early next month. New standards EN ISO 13849-1 and EN/IEC 62061, which are more appropriate to advanced programmable safety-control system implementations, were scheduled to replace EN 954-1 on December 29 2009, commensurate with the European Machinery Directive 2006/42/EC. This change has been widely anticipated since EN ISO 13849-1 was first published in 2006.
