NABL (National Accreditation Board for Testing and Calibration Laboratories) is an autonomous body under QCI (Quality Council of India) that provides formal third-party recognition of laboratory competence. NABL accreditation under ISO/IEC 17025:2017 is the gold standard for chemical, mechanical, electrical, thermal calibration, and medical pathology labs in India.
Key Requirements for NABL Accreditation
To qualify for NABL accreditation, a testing or calibration laboratory must demonstrate technical competence and quality management:
- Quality Manual (ISO/IEC 17025): Documenting laboratory policies, measurement uncertainty evaluation, and equipment calibration routines.
- Proficiency Testing (PT) / Inter-Laboratory Comparisons (ILC): Participating in mandatory PT rounds with accredited PT providers to prove testing accuracy.
- Traceability of Calibration: All reference standards and testing instruments must be calibrated by NABL-accredited calibration laboratories.
- Competent Technical Personnel: Qualified laboratory managers and approved technical signatories meeting official NABL laboratory competency criteria.
The NABL Application & Audit Journey
The accreditation process involves online application submission on the NABL portal, Adequacy Audit of documentation, Pre-Assessment Audit, and Final On-Site Assessment by NABL assessors.
