ec declaration of conformity for two types of machines

Declaration of conformity & CE marking for machines

The certification procedure to attain CE marking is costly and runs according to clearly defined work sequences. On the one hand, an EC installation declaration can be issued for non-production-ready “incomplete” machines and plants. On the other hand, the CE symbol can be attached as a result of an EC declaration of conformity signed with legal effect. In terms of the procedure, it doesn’t matter which option is involved. The process is identical in either case. Essentially therefore, any EC declaration serves as confirmation of conformity for both complete and incomplete machines.

CE marking is necessary not just for individual machines, but where machines are linked or converted too.

Developing the right safety strategy can be costly. Even creating the mandatory documentation is time consuming and laborious, especially when it’s not something you’re use to doing or what you focus on.

CE-CON experts while examining a machine

Not all machines are the same

We essentially distinguish between two types of machine: An incomplete machine is supplied with an installation declaration and does not perform a specific function in and of itself.

A complete machine on the other hand is fully functional with respect to its intended usage, requiring only connection to a power supply. It is recognisable by its permanently attached CE mark and issued EC declaration of conformity.

When it comes to linking incomplete machines with an existing CE marked machine, it is important to check whether such linking constitutes significant modifications to the machine as a whole.

If so, the CE certification procedure must be re-performed for the entire machine or system. If the merging of machinery does not result in significant modifications, it is sufficient to assess the risks at the interfaces and to extend the technical documentation accordingly to include the corresponding text passages. Often, however, the correct classification of machines presents significant hurdles in itself.
