CE marking of machinery - Machinery Directive

Do you design and / or build industrial machines?

Are you a machinery user and have you put together several machines and need to CE mark the assembly line?

If you design machinery, you will already know that before putting them on the market they must be CE marked.

What does the CE marking of machines mean?

The CE marking certifies the conformity of machinery to the applicable Community directives.

The CE marking is physically affixed to the machinery as a label, but it is the final step in a process that aims to guarantee the safety of the machine.

In fact, like many other products, the machines must also comply with the laws in force in the countries in which they are marketed and put into service.

An EC declaration of conformity issued by the manufacturer is finally drawn up for the machine, designed and built in compliance with the applicable directives; the declaration will remain valid for the entire life of the machine itself and will accompany it in future commercial transitions.

If you need to mark CE a machine, or a set of machines, and you are looking for specialist advice, you have come to the right place!

Quadra Srl is a company specialized in technical consultancy to guarantee the safety of your machines and has been doing this task for 27 years


Our technicians can help you with the CE marking of the machinery you produce or use, even in case of substantial changes.

First of all, it will be necessary to identify which directives are applicable and then decide on the most correct and simplest path to comply with them.

Since 1995 we have been providing consultancy for the machinery directive 2006/42 / EC, for example for the assessment of risks, the calculation of PLs, the creation of instruction manuals.

We can help you with activities such as:

  • identification of the regulatory requirements applicable to your type of machines;
  • the analysis of the machine with respect to the requirements of the machinery directive and of the electrical equipment with respect to the requirements of the standard EN 60204-1: 2018;
  • analysis of pneumatic and hydraulic equipment ;
  • risk assessment ;
  • the drafting, or verification, of the machine instruction manual ;
  • instrumental tests (noise, vibrations, optical radiation, electromagnetic fields, electrical safety according to CEI EN 60204-1, measurement of stopping times, electromagnetic compatibility);
  • analysis and verification of control circuits with safety functions (PL & SIL);
  • the validation of the control circuits having safety functions according to the UNI EN ISO 13849-1: 2016 and UNI EN ISO 13849-2: 2013 standards;
  • the validation of software related to safety according to the UNI EN ISO 13849-1: 2016 and UNI EN ISO 13849-2: 2013 standards;
  • the CE marking of assembly line with the issue of the Declaration of Conformity by Quadra Srl as manufacturer.

The services listed above are also applicable to modifications of machines and lines or to the inclusion of partly completed machines in existing assembly production lines.
