Our Accreditation: PNAC LAB 185 Under ISO/IEC 17025:2017

Every test report we issue carries the weight of an internationally recognized accreditation behind it. SAB Labs operates under accreditation number LAB 185, granted by the Pakistan National Accreditation Council (PNAC). PNAC is the sole national body authorized to accredit testing and calibration laboratories in Pakistan.

Our accreditation confirms that we meet the requirements of ISO/IEC 17025:2017, the global benchmark for laboratory competence. This is not a self-declaration. PNAC assessors evaluate our technical staff, test equipment, measurement traceability, quality management system, and the reliability of our test results through regular surveillance audits.

For textile mills, garment exporters, buying houses, and compliance teams working across Pakistan, this accreditation means one thing: when you receive a test report from SAB Labs, the data on it has been produced by a laboratory whose competence has been independently verified by a government-authorized body.

What Our Accreditation Means for You

When a brand like H&M, Nike, Inditex, or PVH asks for test reports from an “accredited laboratory,” they are specifically asking for ISO/IEC 17025 accreditation. Here is what this means in practical terms for your business.

Your reports are accepted internationally. ISO/IEC 17025 is recognized through mutual recognition agreements between accreditation bodies worldwide. A PNAC-accredited report from our Karachi laboratory carries the same technical credibility as one issued by a lab in Germany or the United States.

Your test results are traceable. Every measurement we make is traceable to national or international standards of measurement. Our instruments are calibrated by accredited calibration laboratories, and we participate in proficiency testing programs to verify that our results stay consistent with laboratories around the world.

Your risk of shipment rejection drops. When buyers see the PNAC accreditation mark on your test report, they know the results were not produced in an unverified setup. Accredited reports reduce the chances of re-testing at the buyer’s end, shipment holds, and compliance disputes that cost you time and money.

You get a defensible paper trail. If a compliance question comes up months after shipment, and it often does, an accredited test report from SAB Labs gives you documented, third-party evidence that your product met the required specifications at the time of testing.

Frequently Asked Questions About Our Accreditation

ISO 9001 certifies that an organization has a quality management system in place. It tells you the company follows good processes. ISO/IEC 17025 goes much further. It specifically evaluates the technical competence of a testing laboratory. A lab can hold ISO 9001 certification and still produce unreliable test results because ISO 9001 does not check whether the lab can actually perform tests correctly. ISO/IEC 17025 verifies that the lab knows how to perform the tests, that its equipment is properly calibrated, and that its results are accurate and repeatable. When international buyers ask for "accredited test reports," they mean ISO/IEC 17025, not ISO 9001.

If your buyer requires test reports from an ISO/IEC 17025 accredited laboratory, and most international buyers do, then yes. Our accredited reports carry the PNAC accreditation mark with our accreditation number LAB 185. PNAC is a signatory to the ILAC (International Laboratory Accreditation Cooperation) Mutual Recognition Arrangement, which means our accreditation is recognized by accreditation bodies in over 100 countries. A report from our lab in Karachi holds the same technical standing as a report from an accredited lab anywhere in the world.

PNAC conducts regular surveillance audits to verify that we continue to meet all requirements. Our accreditation is not a one-time certificate that sits on a wall. It requires ongoing compliance, participation in proficiency testing programs, and periodic reassessment by PNAC assessors. Our current accreditation cycle runs until 11 November 2028.

Yes, we perform many tests beyond our formally accredited scope. However, only the tests listed on this page are covered by our PNAC accreditation. Test reports for tests outside the accredited scope will be issued without the PNAC accreditation mark. We clearly indicate on every report which tests fall within our accredited scope and which do not, so there is never any confusion for you or your buyer.

This means our laboratory is a fixed, permanent facility. It is not a mobile setup, a temporary arrangement, or a shared space. PNAC has physically assessed and approved our laboratory premises, including our environmental conditions, equipment installation, sample storage, and overall facility layout. Your samples are tested in a controlled, purpose-built environment.

Ready to Get Your Products Tested by an Accredited Lab?

Send us your samples and receive ISO/IEC 17025 accredited test reports that your buyers will accept without question. Whether you need physical testing, color fastness evaluation, dimensional stability checks, fiber composition analysis, or full RSL compliance screening, every result we deliver is backed by our PNAC accreditation.
