International recognition.
ILAC MRA coverage means accredited results are recognised across signatories. Test reports and calibration certificates move across borders without parallel re-testing.
Product & Regulatory
Technical and management-system readiness for testing and calibration laboratories seeking accreditation by NABL, UKAS, A2LA, or another ILAC signatory.
ISO/IEC 17025 specifies the general requirements for the competence, impartiality, and consistent operation of laboratories. Unlike ISO 9001, which is a management-system standard applicable to any sector, 17025 is specifically for laboratories and carries both management-system and technical competence requirements. Accreditation under 17025 is what distinguishes a lab that delivers results from one whose results are recognised across jurisdictions.
Accreditation is granted by an accreditation body that itself signs the ILAC Mutual Recognition Arrangement, so that a result accredited in one signatory country is recognised in the others. In India, NABL is the national accreditation body; globally, UKAS, A2LA, DAkkS, EGAC, and others perform the same role. The accreditation scope — specific tests, calibration parameters, and ranges — matters at least as much as the fact of accreditation itself.
Third-party testing laboratories in food, pharma, materials, environmental, electrical, mechanical, and biological disciplines; calibration laboratories across dimensional, mechanical, electrical, thermal, and chemical metrology; in-house laboratories that issue results used in regulated decisions (pharma QC, metallurgy, forensic); and reference material producers supplying calibration standards to the community.
ILAC MRA coverage means accredited results are recognised across signatories. Test reports and calibration certificates move across borders without parallel re-testing.
Indian regulators (CDSCO, FSSAI, BIS), EU Notified Bodies, and equivalent regimes routinely require NABL or equivalent accreditation for lab results used in market approval.
Accredited scope items are billable as such. Third-party testing rates for accredited parameters run measurably higher than equivalents without accreditation.
The standard forces honest method validation, control of standards and reference materials, and management of measurement uncertainty — turning folklore practice into evidenced technique.
Participation in ILAC-recognised PT schemes gives the lab external evidence of ongoing competence, not just internal QC.
Impartiality, confidentiality, staff competence management, and document control all receive Clause-level attention. A well-run 17025 lab is a better lab before the certificate arrives.
The 2017 revision reorganised the standard into five substantive clauses plus management-system requirements. Clause 4 covers general requirements — impartiality and confidentiality. Clause 5 covers structural requirements — legal identity, defined management, and responsibilities. Clause 6 addresses resources: personnel, facilities and environmental conditions, equipment, metrological traceability, and externally provided products and services.
Clause 7 is the operational heart of the standard and covers process requirements — review of requests, tenders and contracts; selection, verification, and validation of methods; sampling; handling of test and calibration items; technical records; evaluation of measurement uncertainty; ensuring the validity of results (including PT / interlaboratory comparison); reporting of results; complaints; non-conforming work; control of data and information management. Clause 8 covers management-system requirements, with two options — implement per ISO 9001, or implement the structured management-system requirements given in Clause 8 itself. Most labs choose the latter.
Define the accreditation scope — specific tests, calibration parameters, ranges, and measurement uncertainty — matched to demand and the equipment available. Getting this wrong is the most expensive mistake at pre-assessment.
Calibration traceability back to national or international standards, equipment verification and intermediate checks, and a measurement-traceability register that the assessor will accept.
Validation for in-house methods, verification for adopted standard methods, documented measurement uncertainty budgets, and proficiency testing enrolment.
Structured management system (Option B) or ISO 9001 integration (Option A), internal audit, and management review to the depth the national accreditor will apply.
Coach the lab through pre-assessment, then attend the full assessment and witness-audits of specific tests / calibrations. Support non-conformity closure through to accreditation.
A lab with well-equipped facilities, competent technical staff, and existing PT participation typically reaches accreditation in sixteen to twenty-four weeks from engagement start. Labs starting without PT participation, or expanding scope with new methods, typically run to six to nine months. PT cycle availability is often the rate-limiting variable.
Fees depend on scope size (number of tests / calibration parameters), whether method validation is already in place, and the number of sites. Accreditation body fees — application, assessment, annual — are separate and billed directly by the accreditor.
Strictly, NABL is an accreditation body and laboratories are accredited rather than certified. The standard accredited against is ISO/IEC 17025. Functionally, "NABL accredited to ISO/IEC 17025" and similar phrasings for UKAS, A2LA, etc. are the conventional descriptions.
Option A of the 2017 revision accepts an ISO 9001 management system. Option B provides a structured management system within 17025 itself. Most labs use Option B to avoid running two parallel management systems.
Frequency depends on the test or calibration discipline and the accreditation body's published policy. A common baseline is at least one PT round per accredited test / parameter per accreditation cycle, with higher frequency for high-risk or high-volume work.
Calibration establishes the relationship between measurement results and reference values, with associated uncertainty. Verification confirms that a device meets a specified requirement. A 17025 calibration lab performs calibration; a testing lab performing verifications typically uses calibrated equipment without itself issuing calibration certificates.
Yes — scope extensions are a routine assessor-driven process. We typically plan scope expansions across accreditation cycles so validation work and PT participation line up efficiently.
