06 VALIDATION –
REAL-WORLD TESTING FOR YOUR SAFETY MEASURES
Validation is the final testing step, during which the protective measures are tested directly on the machine for their functionality and effectiveness. The goal is to ensure that all safety requirements according to EN ISO 13849 are met and that the protective measures function reliably in practice.
With Wieland, you gain a partner who not only provides specialized testing methodologies and tools but also supports you on-site – ensuring a compliant and safe implementation.

Goal:
Test the technical protective measures directly on the machine to ensure they function correctly and meet the defined safety requirements according to EN ISO 13849.
Description:
Validation is an essential step to verify the effectiveness of technical protective measures. It involves on-site testing to confirm that all safety functions operate reliably and as specified. This step forms the foundation for the final release of the machine.
- Safety Engineers: Perform and document validation tests.
- CE Coordinators: Integrate validation results into the technical documentation.
- Designers/Engineers: Support optimization of protective measures if the validation requires adjustments.
Target Audience:
⚙️ CHALLENGES & COMMON ISSUES
- Uncertainty in Practical Testing:
Validation demands thorough testing of protective measures directly on the machine. Without standardized processes or specific tools, there’s a risk that safety gaps may go unnoticed.
- Complexity of Norm Requirements:
Complying with all EN ISO 13849 requirements can be challenging. Documentation and proof of validation are particularly time-consuming and prone to error.
- Lack of Experience with Testing Methods:
Specialized methods and tools are needed to efficiently and compliantly validate safety functions. Without this experience, errors or delays in the CE process may occur.

YOUR ORIENTATION
IN THE CE PROCESS
You are currently at Step 06: Validation.
This step verifies whether the protective measures meet the safety requirements not just in theory, but also in practice. It completes the review of the safety functions and ensures that your machine meets the highest standards.
To keep an overview of the entire CE process, you’ll find the summary here:


01 Research
Identify all applicable standards, directives, and legal requirements for your machine type – the foundation for a legally secure and smooth CE process.

02 Risk Assessment
Evaluate all potential hazards throughout the machine’s lifecycle according to EN ISO 12100 and lay the groundwork for a sound safety concept.

04 Safety Engineering
Bring your safety concept to life with well-designed technology and develop standards-compliant safety software – for a safe and productive machine.

03 Safety Concept
Derive specific protective measures based on the risk assessment – compliant with EN ISO 13849-1 and tailored to your operational needs.

05 Verification
Verify the implementation of protective measures in line with EN ISO 13849-1 – especially with regard to the required performance level.

07 Documentation
Ensure that all records – from risk assessment to validation – are complete, consistent, and CE-compliant.

09 Inspection
Conduct regular inspections to ensure the functionality of your safety measures throughout the machine’s entire lifecycle.

06 Validation
Test directly on the machine whether all technical safety measures function reliably and meet the specified requirements.

08 Evaluation & Final Report
Compile and confirm all relevant evidence in a final report – forming the basis for the Declaration of Conformity.
