Does a combination of machines have to be CE marked?

Yes. When you combine a series of complete machines and / or partly completed machines so they operate as a single assembly line (ie under a single control system), you have to:

  • Apply the CE mark
  • Issue a Declaration of Conformity
  • Produce / keep a technical file

This must be done for the complete assembly line as a whole, even if each individual machine has its own CE mark. The technical file only needs to contain the design details and drawings of any control systems and other parts you’ve had to supply or modify, and the Declarations of Conformity / Incorporation for each of the items in the line.
