CMC Certification
Manufacturers and laboratories often calibrate their instruments in their own facilities. With the VSL CMC Certification, you demonstrate that your calibration or test facility is technically reliable, follows controlled procedures, and achieves the best attainable measurement uncertainty under normal operating conditions.
What is CMC?
CMC stands for Calibration and Measurement Capabilities: the measurable capability of a facility, including the best achievable uncertainty.
VSL independently verifies this capability according to JCGM 100:2008 “Evaluation of measurement data – Guide to the expression of uncertainty in measurement”.

Why obtain CMC‑certificering?
A VSL CMC Certificate shows that your facility:
- Has been independently assessed by an internationally recognised metrology institute
- Uses traceable instruments and validated calibration models
- Operates according to documented and stable procedures
- Delivers results that customers and auditors can trust
Certified organisations may mark their calibration results with the VSL CMC Certified logo.
How the assessment works?
VSL metrologists evaluate:
- The technical performance of the installation
- All vital components and their traceability
- The correctness of calibration models
- The presence of operational and maintenance procedures
- Live witnessing of calibration activities
After the assessment, you receive the CMC Certificate including the defined uncertainty and instructions to maintain traceability.
The certification remains valid for two years, provided the procedures are followed.
Two-yearly audit
Every two years, VSL carries out a technical audit to ensure that your facility still operates within the certified CMC values. This includes on‑site witnessing.
Who is it for?
The VSL CMC Certification is suitable for:
- Instrument manufacturers
- Laboratoria met interne kalibratielijnen
- Organisations wanting independent confirmation of measurement quality
Benefits for your organisation
- Stronger competitive position
- Independent quality assurance
- Increased confidence from customers and auditors
- Clear uncertainty values and traceability guidance
