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

<h2>Why accreditation matters for your audit</h2>
<p>If your quality system runs to ISO 9001, ISO/IEC 17025 or a regulated standard (pharma, aerospace, medical devices), your auditor will ask one question about your measuring equipment: <em>can you prove it was calibrated by a competent, traceable source?</em> A calibration certificate from a <strong>non-accredited</strong> provider may not satisfy that requirement — because nothing independent vouches for that provider's competence. An accredited certificate does.</p>

<h2>Accredited vs non-accredited calibration</h2>
<ul>
<li><strong>Accredited:</strong> the lab's competence is independently assessed; the certificate is traceable to national/international standards and is recognised in audits.</li>
<li><strong>Non-accredited:</strong> a certificate is issued, but there is no third-party assurance of the methods, uncertainty, or traceability behind it.</li>
</ul>

<h2>How to check a lab's accreditation</h2>
<p>Ask for two things: the lab's <strong>accreditation number</strong> and its <strong>scope of accreditation</strong> (the specific parameters and ranges it is accredited for). A genuine lab will share both. Unitest Instruments is SAC-SINGLAS accredited to ISO/IEC 17025 under accreditation number <strong>LA-2023-0845-C</strong>.</p>
