The CE mark on a machine is one of the most visible outcomes of the conformity assessment process. Most of the work, however, happens before the mark is applied.
Depending on the machine, the manufacturer may need to identify applicable requirements, assess risks, prepare technical documentation, verify safety measures, document relevant checks and tests, and finally prepare and sign an EU Declaration of Conformity.
This is why a seemingly simple question — “How do I CE mark my machine?” — can quickly turn into a complete documentation project.
The CE mark is the end of the process, not the beginning
CE marking should not start with designing a label or filling in a declaration template.
The manufacturer first needs to determine which requirements apply to the specific machine and how conformity with those requirements will be demonstrated.
In practice, the process may involve:
requirements → risks → design and safety measures → checks and tests → technical documentation → Declaration of Conformity → CE marking.
If an important part of that chain is missing, adding a single document may not solve the underlying problem.
What documentation may be required for CE marking machinery?
There is no universal document checklist that applies identically to every machine.
The required documentation depends on the product, its intended use, its construction and the applicable requirements.
A machinery documentation package may include the following.
1. Identification of applicable requirements
The first step is determining which EU requirements apply to the particular machine or equipment.
This determines the framework for the rest of the conformity assessment.
2. Identification of relevant standards
Relevant standards can provide technical methods and safety principles for addressing specific requirements.
Not every standard applies to every machine, so they need to be selected according to the actual product.
3. Risk assessment
A machinery risk assessment should address the actual hazards associated with the machine.
This can include intended use, reasonably foreseeable misuse, hazardous areas, mechanical and electrical hazards, and the protective measures implemented to reduce those risks.
4. Technical file
The technical file brings together the information supporting the machine’s conformity.
Depending on the project, it may contain:
- a general description of the machine;
- design and assembly drawings;
- electrical diagrams;
- pneumatic or hydraulic diagrams;
- technical information for relevant components;
- information on standards used;
- risk assessment;
- calculations;
- inspection and test results;
- operating instructions;
- other evidence supporting conformity.
At this point, the real scale of the documentation work often becomes apparent.
5. Operating and safety instructions
Instructions need to describe the actual machine.
A generic template is of limited value if it does not correspond to the machine’s real operation, adjustment, maintenance and safety requirements.
6. Inspection and test records
Where checks, measurements or tests are needed, it may also be necessary to document what was checked, how it was checked and what the result was.
Simply knowing internally that “we tested it and it worked” may not provide sufficient documented evidence.
7. EU Declaration of Conformity
The Declaration of Conformity should not be treated as the starting point of the CE marking process.
It is prepared once the relevant conformity assessment activities and supporting documentation have been completed.
The final declaration is issued and signed under the responsibility of the manufacturer.
8. Machine identification and CE marking
The machine also needs appropriate identification information.
For serial production, additional practical questions arise around serial numbers, document versions, final inspections and maintaining documentation for individual machines or product variants.
“But the machine is already built.”
This is a common situation.
The machine works. Electrical drawings may exist. Component documentation may have been supplied by manufacturers. There may even be a draft manual.
Then somebody asks for the CE documentation.
The challenge is that the relevant information may be spread across drawings, folders, emails, supplier documents and the knowledge of different people.
The first task is therefore often to determine:
- what documentation already exists;
- which requirements apply;
- whether a risk assessment has been completed;
- whether the documentation matches the machine as built;
- which checks and tests have been documented;
- which documents are missing;
- what still needs to be completed before the declaration can be finalised.
What initially looks like one missing document can therefore become a structured documentation project.
Can we prepare the CE documentation ourselves?
Yes.
Manufacturers can prepare their own documentation, and outsourcing documentation work does not transfer the manufacturer’s ultimate responsibility for product conformity.
The practical question is whether the company has the time, knowledge and internal process to identify the relevant requirements, assess risks, document the necessary checks and bring all of the information together consistently.
For a simple machine, this may be relatively manageable.
For a more complex machine, automated equipment, multiple hazard zones or incomplete source information, a significant part of the work may be determining what needs to be done in the first place.
CE documentation is easier when it starts before the machine is finished
Ideally, conformity assessment and documentation are considered during design and construction.
This makes it easier to connect identified risks, safety measures, required checks and documentation directly to the machine’s actual design.
Documentation can also be prepared for an existing machine, but the review may identify additional checks, evidence or technical measures that need attention.
Not sure where to start?
You do not need to identify every missing document before asking for assistance.
CE Point can start by reviewing the machine and the information already available. We can identify existing documentation, gaps and next steps and then define the scope for preparing or organising the required CE marking documentation.
