NABL OR ISO 17025 Accreditation

Introduction to NABL & ISO/IEC 17025

ISO/IEC 17025:2017 is the international standard that specifies the general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. In India, accreditation to ISO/IEC 17025 is granted by the National Accreditation Board for Testing and Calibration Laboratories (NABL), which operates under the Quality Council of India (QCI), Quality & Accreditation Institute (QAI) etc.

NABL accreditation is a formal recognition that a laboratory is technically competent, follows a robust quality management system, and produces reliable, valid, and internationally acceptable test or calibration results.

For laboratories aiming to serve regulated industries, government bodies, or global clients, NABL accreditation is not just a recognition—it is a necessity.

What is NABL Accreditation?

NABL Accreditation is a third-party assessment process through which laboratories are evaluated against the requirements of ISO/IEC 17025:2017. It confirms that a laboratory:

• Has competent personnel
• Uses validated test and calibration methods
• Maintains traceability to national/international standards
• Operates with impartiality and integrity
• Produces technically valid results

NABL accreditation enhances confidence among regulators, customers, and international stakeholders

Who Needs ISO/IEC 17025 / NABL Accreditation?

NABL accreditation is applicable to:

• Testing Laboratories
  • Chemical
  • Mechanical
  • Electrical
  • Biological
  • Food & Water
  • Environmental
  • Textile & Material Testing
• Calibration Laboratories
  • Mechanical
  • Electrical
  • Thermal
  • Optical
  • Radiological
• • Medical & Diagnostic Labs (select scope)

Why NABL Accreditation is Important?

Key Benefits of NABL Accreditation.

• Recognition of technical competence
• International acceptance of test/calibration reports
• Compliance with regulatory and statutory requirements
• Enhanced customer confidence & credibility
• Eligibility for government & PSU tenders
• Reduced risk of disputes & re-testing
• Improved laboratory management & efficiency

NABL-accredited reports are accepted by regulators, courts, inspection bodies, and overseas authorities under mutual recognition arrangements (ILAC/APLAC).

Structure of ISO/IEC 17025:2017

TISO/IEC 17025:2017 is based on process approach, risk-based thinking, and impartiality. The standard is divided into the following key clauses:

Clause 4 – General Requirements

• Impartiality
• Confidentiality

Clause 5 – Structural Requirements

• Legal identity.
• Organizational structure.

Clause 6 – Resource Requirements

• Personnel competence
• Facilities & environmental conditions
• Equipment & calibration
• Metrological traceability
• External providers

Clause 7 – Process Requirements

• Review of requests, tenders & contracts
• Method selection & validation.
• Sampling
• Handling of test items
• Technical records
• Measurement uncertainty
• Ensuring validity of results
• Reporting of results
• Complaints, non-conforming work

Clause 8 – Management System Requirements

• Document control
• Risk & opportunity management
• Internal audits
• Management review
• Corrective actions

NABL Accreditation Process

Step 1: Application to NABL

• Submission of application through NABL portal
• Selection of scope of accreditation
• Payment of application fees

Step 2: Document Review

• Quality Manual
• SOPs & test methods
• Technical records
• Equipment calibration & traceability

Step 3: Pre-Assessment (Optional but Recommended)

• Gap analysis against ISO/IEC 17025
• Identification of non-conformities

Step 4: Final Assessment

• On-site assessment by NABL assessors
• Technical witnessing of tests/calibrations
• Evaluation of personnel competence

Step 5: Closure of Non-Conformities.

• Corrective actions
• Submission of evidence

Step 6: Grant of NABL Accreditation

• Approval by NABL Accreditation Committee
• Issuance of accreditation certificate

Validity & Surveillance

• Initial validity: 4 years
• Surveillance: Periodic assessments by NABL
• Renewal: Required before expiry

Continuous compliance is mandatory to retain accreditation.

Common Challenges in NABL Accreditation

• Incorrect scope definition
• Inadequate technical records
• Poor uncertainty calculation
• Non-validated test methods
• Lack of traceability
• Weak internal audit & management review

(Exact applicability depends on the notified Indian Standard.)
