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 technical signatories meeting NABL 165 / NABL 130 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.
