Under the existing Machinery Directive 98/37/EC safety components are required to have a Declaration of Conformity but not be CE marked. However, safety components that incorporate electrical/electronic componentry - such as safety relays - will be CE marked under the LVD and EMC Directives. When the new Machinery Directive 2006/42/EC comes into force on 29 December 2009, CE marking will be required for all of the products subject to the Directive, with the exception of partly completed machinery.
Because most safety components (but not, for example, guards) already have a CE mark applied under the LVD or EMC Directives, machine builders will see no visual difference on these safety components after 29 December 2009, though the corresponding documentation will continue to reflect the version of the Machinery Directive in force at the time the component was placed on the market.
Note that safety components are excluded from the scope of the new Directive if they are supplied as identical spare parts by the manufacturer of the original machinery - see Article 1, paragraph 2(a).
