Accredited Calibration (ISO/IEC 17025)

Accredited calibration provides a higher level of documented confidence and is required when customers, authorities, or internal quality systems demand independent verification of measurement performance.

At Insatech, accredited calibrations are performed in accordance with ISO/IEC 17025. We are audited by DANAK (Danish Accreditation Fund). This ensures that methods, equipment, environmental conditions, and personnel competence are suitable for the task, and that Calibration Measurement Capabilities (CMC) are calculated and stated.

If you are unsure whether accredited or traceable calibration is required for your application, our Calibration Engineers are happy to advise you.

When Is Accredited Calibration Required?

Accredited calibration is typically selected when:

Regulatory requirements or industry standards mandate accredited calibration
Customers require independent, third-party audited and verified documentation
Measurements are critical to product quality, safety, or compliance
Audits require transparent documentation of measurement uncertainty
Acceptance criteria must be evaluated against stated measurement capability

In regulated and high-risk environments, accredited calibration provides a stronger and more transparent documentation basis than traceable calibration.

What Makes Accredited Calibration Different?

Accredited calibration goes beyond traceability alone. It ensures that the entire calibration process is controlled and evaluated according to internationally recognised standards.

Accredited calibration includes:

Calibration performed according to defined measurement ranges and capabilities
Stated and calculated measurement uncertainty as CMC
Controlled environmental conditions
Defined requirements for personnel competence
Independent oversight and regular audits by the accreditation body

This framework ensures consistent, reliable results and reduces the need for time-consuming supplier evaluations.

Instruments We Calibrate Accredited

We perform accredited calibration for the following range of instruments:

Total Organic Carbon Analyzers
Both in our laboratory and on-site - we are only one in the worls (only for Sievers)
Conductivity equipment
- Cell constant - market leading CMS
- Electrical
- Comparison
Temperature sensors

Traceable vs Accredited Calibration: Quick Comparison

	Traceable Calibration	Accredited Calibration (ISO/IEC 17025)
Primary purpose	Determine Calibration Measurement Capabilities (CMC) and maintain traceability	Provide independent, third-party audited confidence
Traceability	Yes – to recognised standards	Yes – with independent accreditation
Measurement uncertainty stated	Not necessarily	Yes – calculated and stated
Regulatory acceptance	Depends on industry and application	Accepted by authorities and regulators
Audit readiness	Suitable for many internal quality systems (e.g. ISO 9001)	Strong documentation basis for audits
Environmental control requirements	Not formally defined	Defined and controlled
Personnel competence requirements	Not formally specified	Defined and verified
Independent oversight	No	Yes (e.g. DANAK)
Typical use cases	Preventive maintenance, non-critical measurements	Critical measurements, regulated environments
Cost and complexity	Lower	Higher, but with stronger documentation
