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 and are subject to independent oversight by DANAK (Danish Accreditation and Metrology Fund). This ensures that methods, equipment, environmental conditions, and personnel competence are suitable for the task and that measurement uncertainty is 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 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 capability
• Stated and calculated measurement uncertainty
• 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 Typically Calibrate

We perform traceable calibration for a wide range of instruments, including:

• TOC equipment (on-site)
• Conductivity equipment
• Temperature sensors
• TOC analyzers

If you require calibration of other instrument types, please contact us to discuss your specific requirements.

Accredited vs Traceable Calibration (SHARED)

The table below highlights the key differences between accredited and traceble calibration:
Traceable vs Accredited Calibration – Quick Comparison

While both calibration types establish traceability, the choice depends on your application and documentation requirements.

• Traceable calibration provides documented traceability and is sufficient for many industrial applications
• Accredited calibration provides independent verification, stated measurement uncertainty, and a stronger documentation basis

If accreditation is not required, traceable calibration may be the most practical and cost-effective choice.
