The DGUV Test testing and certification bodies are very involved in the national and European co-ordination groups of the approved/notified bodies and provide several chairpersons for those groups.
The 'Recommendation for Use' (RfU) sheets of the european co-ordination groups help the notified bodies to harmonize testing and certification.

Horizontal RfU sheets apply to all types of machinery listed in Annex IV of the Machinery Directive. Other RfU sheets are of a vertical nature and apply more specifically to a particular category of machinery listed in Annex IV.
