CE marking according to the Machinery Directive

Plant planners and manufacturers

The Machinery Directive 2006/42/EC (MD) defines the prerequisites under which machinery and partly completed machinery may be made available on the market or put into operation for the first time in the European Economic Area (EEA). In principle, the MD is intended for the manufacturer. Due to the linking of (incomplete) machines with a superordinate control system to form a plant or due to modifications to machines or plants after they have been put into operation, operators frequently also become so-called “self-manufacturers” in practice. Depending on the case, the manufacturer or own manufacturer must affix the CE marking and draw up technical documentation, in particular the documents, for partly completed machinery or for machinery before it is made available on the market or put into service and, where appropriate, before it is put into service:

  • Risk assessment
  • Assembly or operating instructions
  • Declaration of incorporation or EU / EC declaration of conformity

The Machinery Directive (MD) is also applicable to large industrial plants (e.g. those in the chemical industry). These installations can usually be divided into individual functional units related to production and safety, for each of which the requirements of the MRL must be complied with.


CE coordination

  • Contract design within the procurement process
  • Research into guidelines and standards
  • Evaluation of supplier documentation
  • Product classification


  • Carrying out/facilitating risk assessments (including with MBT-RAT)
  • Templates for assembly and operating instructions
  • Preparation of EU / EC declarations of conformity / declarations of incorporation
  • Expert opinions on the interlinking of machinery
  • Evaluation of modifications regarding a “significant change”
  • Verification of the safety features and mathematical validation of the performance level (PL)


  • Fundamentals of the Machinery Directive
  • Fundamentals of risk assessment (including MBT-RAT)
  • Mathematical validation of the performance level (PL) with the SISTEMA software

The weyer group advises and supports you in the implementation of the formal requirements of the MRL for your machine or plant.
