National Accreditation Board for Testing and Calibration Laboratories (NABL).
National Accreditation Board for Testing & Calibration Laboratories (NABL) is an autonomous society providing Accreditation (Recognition) of Technical competence of a testing, calibration, medical laboratory & Proficiency testing provider (PTP) & Reference Material Producer (RMP) for a specific scope following IEC/ISO17025:2017, ISO 15189:2012, IEC/ISO 17043:2010  & IEC/ISO 17034:2016  Standards. It has Mutual Recognition Arrangements with Asia Pacific Laboratory Accreditation Cooperation (APLAC), Mutual Recognition Arrangement (MRA), International Laboratory Accreditation Cooperation (ILAC)
NABL provides accreditation in all major fields of Science and Engineering such as Biological, Chemical, Electrical, Electronics, Mechanical, Fluid-Flow, Non-Destructive, Photometry, Radiological, Thermal & Forensics under testing facilities and Electro-Technical, Mechanical, Fluid Flow, Thermal, Optical & Radiological under Calibration facilities. NABL also provides accreditation for medical testing laboratories. In addition, NABL also offers accreditation for Proficiency testing providers & Reference Material producers and is now signatory to APLAC MRA for both.
What is Accreditation
Accreditation is the third party attestation related to a conformity assessment body conveying the formal demonstration of its competence to carry out specific conformity assessment task. Conformity Assessment Body (CAB) is a body which includes Testing including medical Laboratory, Calibration Laboratory, Proficiency Testing Provider, Certified Reference Material Producer.
Benefits of accreditation
NABL is a Full member (ILAC MRA signatory) to ILAC  as well as APLAC Mutual Recognition Arrangements (MRA), based on mutual evaluation and acceptance of other MRA Partner laboratory accreditation systems. Such international arrangements facilitate acceptance of test / calibration results between countries to which MRA partners represent.
This developing system of international mutual recognition agreements between accreditation bodies has enabled accredited laboratories to achieve a form of international recognition, and allowed test data accompanying exported goods to be readily accepted on overseas markets amongst the countries which have already qualified as significant to ILAC Arrangements. This effectively reduces costs for both the exporters and the importers, as it reduces or eliminates the need for products to be re-tested in another country.
It is about assessing and determining the reliability of data that they are producing against their testing. The tool of Inter-Laboratory comparison is used to determine the proficiency of testing. All Accredited Laboratories have to successfully participate in at least one inter-laboratory comparison.
All the accredited laboratory have to follow ISO/IEC 17025 to maintain quality management system in testing and calibration.
Measurement audits are also undertaken. NABL also undertake proficiency testing programme for its accredited as well as applicant laboratories.
NABL undertakes following courses:-
- ISO/IEC 17025 Assessor's Training Course
- ISO 15189 Assessor's Training Course
Scope of accreditation
Its scope for accreditation extends to:-
Testing Laboratories: Biological (NABL 102), Chemical (NABL 103), Electrical (NABL 104), Electronics (NABL 105), Fluid-Flow (NABL 106), Mechanical (NABL 107), Non-Destructive (NABL 108), Photometry (NABL 109), Radiological (NABL 110), Thermal (NABL 124)
