CEN has confirmed to MachineBuilding.net that EN 954-1 presumption of conformity to the Machinery Directive has been prolonged for two years, up to 31 December 2011. If you are not familiar with the background to this announcement, read this article: EN 954-1 final decision - transition extension confirmed.
Furthermore, Marie Poidevin of CEN stresses that the two-year extended transition period (in which users can choose between EN 954-1 or EN ISO 13849-1) is definitely confirmed, even though the latest list of standards harmonised to the Machinery Directive 2006/42/EC (published 18 December 2009) does not include EN 954-1.

An updated list of harmonised standards with EN 954-1 is expected to be published within a week. [STOP PRESS: See EN 954-1 harmonised to Machinery Directive 2006/42/EC - Ed]
