Quick Answer
Prism Calibration Centre (NABL CC-2480) is an ISO/IEC 17025:2017 accredited calibration laboratory in Gujarat, assessed and accredited by NABL (QCI) for competence in temperature, pressure, electrical, dimensional, mass, flow, and biomedical calibration.
Key Takeaways
- ISO/IEC 17025:2017 is the global benchmark for calibration laboratory competence.
- NABL accreditation in India is based on ISO/IEC 17025:2017 assessment.
- Key ISO 17025 requirements: impartiality, management system, technical competence, measurement uncertainty.
- Prism has held ISO/IEC 17025 accreditation continuously since 2004 (NABL CC-2480).
- ISO 17025 accreditation is assessed every 2 years by NABL technical assessors.
What Is ISO/IEC 17025:2017?
ISO/IEC 17025:2017 is the international standard specifying general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. It was revised in 2017 (from 2005 edition) to align with ISO 9001:2015 and introduce stronger requirements for impartiality, risk-based thinking, and technology-neutral approaches (replacing 'documents' and 'records' with 'documented information').
| ISO 17025 Clause | Key Requirement |
|---|---|
| Clause 4 — General Requirements | Impartiality and confidentiality |
| Clause 5 — Structural Requirements | Organisation, responsibility, management |
| Clause 6 — Resource Requirements | Personnel, equipment, metrological traceability |
| Clause 7 — Process Requirements | Method validation, calibration, handling, reporting |
| Clause 8 — Management System | Documentation, control, internal audit, management review |
How Prism Meets ISO/IEC 17025:2017 Requirements
Impartiality
Prism operates as an independent calibration lab — no conflict of interest with instrument manufacturers or repair services.
Technical Competence
All calibration engineers hold engineering degrees and undergo annual NABL-approved training in calibration methods and uncertainty evaluation.
Traceability
Reference standards calibrated by NPL India or BIPM-recognised NMIs. Unbroken traceability chain documented for every calibration.
Measurement Uncertainty
Full uncertainty budgets evaluated per GUM (ISO/IEC Guide 98-3) and EURACHEM/CITAC for all calibration activities.
Difference Between ISO 9001 and ISO/IEC 17025
ISO 9001 is a quality management system standard for any organisation. ISO/IEC 17025 is specifically for laboratories and has much more rigorous technical requirements for measurement capability, uncertainty, and traceability. A lab can be ISO 9001 certified but NOT accredited to ISO 17025 — only NABL assessment confers 17025 accreditation status. Many industries mistakenly accept ISO 9001 lab certificates when ISO 17025 (NABL) is actually required.
Frequently Asked Questions
Is NABL accreditation the same as ISO 17025 certification?
NABL accreditation is based on ISO/IEC 17025:2017. When NABL accredits a lab (like Prism, CC-2480), it means the lab has been assessed by NABL technical experts to meet all ISO 17025 requirements. It is more than a self-certification — it is third-party accreditation.
How often is ISO 17025 accreditation renewed?
NABL conducts an on-site reassessment every 2 years (biennial). Annual surveillance visits are also conducted to verify continued compliance. Prism has maintained continuous NABL accreditation since 2004.
What is the difference between accreditation and certification?
Certification (e.g., ISO 9001) is granted by a certification body based on document review and audit. Accreditation (e.g., NABL for ISO 17025) is granted by an accreditation body based on technical competence assessment, including on-site testing of calibration capability. Accreditation is technically more rigorous.
Can a non-NABL lab claim ISO 17025 compliance?
A lab can internally implement ISO 17025 without NABL accreditation, but it cannot issue 'NABL-accredited' certificates. For regulatory compliance in India (ISO 9001, IATF, Schedule M), NABL accreditation is what is specifically required.
Which version of ISO 17025 does Prism comply with?
Prism complies with ISO/IEC 17025:2017, the current edition, as assessed by NABL during its most recent on-site assessment.
