What NABL accreditation is
NABL — the National Accreditation Board for Testing and Calibration Laboratories — accredits testing and calibration laboratories in India against ISO/IEC 17025:2017. Accreditation is granted for a defined scope: specific tests, on specific products or materials, using specific methods. It is formal recognition that the lab is competent to produce valid results for that scope.
For many labs it's a commercial necessity — buyers, regulators and BIS lab recognition often expect NABL-accredited results.
What a consultant actually does
Gap assessment: compare your current practices, equipment, records and staffing against ISO/IEC 17025 and NABL's specific requirements, and give you a prioritised list of what to fix.
Scope definition: help you decide which tests and methods to put in scope first. A focused initial scope gets accredited faster and can be extended later.
Documentation: build a quality manual and procedures that describe how your lab really works — not a generic template.
Technical support: method validation or verification, measurement uncertainty estimates, metrological traceability through calibrations, and planning proficiency testing or inter-laboratory comparisons.
Training, internal audit and management review: train your staff on the system, run a mock internal audit, and help you close the gaps before NABL's assessors arrive.
Application and assessment support: prepare the NABL application and help you respond to non-conformities raised during assessment.
What stays your responsibility
A consultant cannot be accredited on your behalf. Your staff must perform the tests competently, keep the records honestly, and run the quality system every day. NABL's assessors interview your people and witness your tests — a system that exists only on paper fails quickly.
Equipment, calibration, environmental conditions and participation in proficiency testing are also yours to fund and maintain.
The accreditation journey, step by step
| Step | What happens |
|---|---|
| 1. Gap assessment | Measure the lab against ISO/IEC 17025 and NABL requirements |
| 2. Implementation | Documentation, training, calibration, method validation, uncertainty, proficiency testing |
| 3. Internal audit and management review | Run the system for real and fix what the audit finds |
| 4. Application | Apply to NABL online with the proposed scope, fees and documents |
| 5. Document review | NABL reviews your documentation and raises queries |
| 6. Assessment | Assessors visit, interview staff, witness tests and raise non-conformities |
| 7. Corrective action | Close every non-conformity with evidence |
| 8. Accreditation | Certificate and scope issued; surveillance and reassessment follow |
Questions to ask before you hire a consultant
Have you taken labs in our discipline (chemical, mechanical, electrical, biological and so on) through NABL accreditation, and can we speak to one?
Will you do a gap assessment before quoting, or is this a fixed package?
Who will write our documents, and how will you make sure they match our actual practice?
How will you handle method validation and measurement uncertainty for our specific tests?
What happens after accreditation — will you support surveillance and scope extensions?
Red flags
A guarantee of accreditation, or of a fixed date — only NABL decides.
Copy-paste manuals with another lab's name barely removed. Assessors spot them immediately.
Any suggestion to create records after the fact, or to manage proficiency-testing results. That isn't a shortcut; it puts the whole accreditation — and the lab's reputation — at risk.
No plan for your staff to understand and own the system once the consultant leaves.
What it costs
NABL's own charges — application fee, assessment charges based on assessor-days, and an annual fee — are published by NABL and vary with your discipline and scope. On top of that come consultancy fees, calibration, proficiency testing, any equipment you need, and staff time. A small lab with a narrow scope costs far less to accredit than a multi-discipline lab, which is another reason to start with a focused scope.
How TechbyDR Services helps
We support testing laboratories from gap assessment to accreditation and beyond — documentation that fits how your lab actually works, method validation and uncertainty, internal audits, the NABL application, assessment support and non-conformity closure, and help with scope extensions and BIS lab recognition afterwards.
FAQs
Is a consultant mandatory for NABL accreditation?
No. Many labs use one because ISO/IEC 17025 implementation is technical and time-consuming, but NABL accredits the lab on its own merits either way.
Which standard does NABL accredit testing labs against?
ISO/IEC 17025:2017, along with NABL's own specific criteria and policies.
Can a consultant guarantee NABL accreditation?
No. Accreditation decisions are made only by NABL after assessment. Treat any guarantee as a red flag.
Should we start with our full test scope?
Usually not. A focused initial scope for your most important tests gets accredited faster; you can extend the scope later.
