What Is SAC-SINGLAS Accreditation — and Why It Matters for Your Audit

SAC-SINGLAS accreditation is formal, independent recognition that a calibration laboratory is technically competent to the ISO/IEC 17025 standard. In Singapore it is granted by the Singapore Accreditation Council. When a lab is SAC-SINGLAS accredited, its calibration certificates carry recognised measurement traceability — exactly what your own auditor is looking for.

Why accreditation matters for your audit

If your quality system runs to ISO 9001, ISO/IEC 17025 or a regulated standard, your auditor will ask one question about your measuring equipment: can you prove it was calibrated by a competent, traceable source? A certificate from a non-accredited provider may not satisfy that — because nothing independent vouches for that provider's competence. An accredited certificate does.

Accredited vs non-accredited calibration

• Accredited: competence is independently assessed; the certificate is traceable and recognised in audits.
• Non-accredited: a certificate is issued, but with no third-party assurance of methods, uncertainty or traceability.

How to check a lab's accreditation

Ask for two things: the lab's accreditation number and its scope of accreditation. Unitest Instruments is SAC-SINGLAS accredited to ISO/IEC 17025 under accreditation number LA-2023-0845-C — see our accreditation & scope.
