Directive 2006/42/EC is a revised version of the Machinery Directive, the first version of which was adopted in 1989. The new Machinery Directive has been applicable since 29th December 2009. The Directive has the dual aim of harmonising the health and safety requirements applicable to machinery on the basis of a high level of protection of health and safety, while ensuring the free circulation of machinery on the EU market. The revised Machinery Directive does not introduce radical changes compared with the previous versions. It clarifies and consolidates the provisions of the Directive with the aim of improving its practical application.
