The requirements of the directives are to ensure that manufacturers have identified and addressed all aspects of design and manufacturing that could impact safety and the safe operations of the equipment.
The actions required to become compliant with the directives vary according to which directive(s) apply and the type or classification of the equipment as defined by the directive(s). However, there are some general steps you should follow:
1. Determine which, if any, EU directives apply to your product(s).
2. Determine the extent to which your product already complies with the essential requirements of the directives.
3. Choose conformity assessment routes. Depending on the nature of the equipment or product, you may be able to implement and declare compliance and affix the CE mark without assistance or service from an external company. In some cases the directives require and mandate that the services of a notified body, like DNV, be used.
