# National Accreditation Board for Testing and Calibration Laboratories

National Accreditation Board for Testing and Calibration Laboratories (NABL) provides accreditation to Conformity Assessment Bodies (Laboratories) in India. NABL Schemes include Accreditation (Recognition) of Technical competence of testing, calibration, medical testing laboratories, Proficiency testing providers (PTP) & Reference Material Producers (RMP) for a specific scope following ISO/IEC 17025, ISO 15189, ISO/IEC 17043 & ISO 17034:2016 Standards. It has Mutual Recognition Arrangement (MRA) with Asia Pacific Accreditation Cooperation (APAC), International Laboratory Accreditation Cooperation (ILAC).
NABL is a constituent board of Quality Council of India which is an autonomous body setup under Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry, Government of India.
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 disciplines under testing facilities and Electro-Technical, Mechanical, Fluid Flow, Thermal, Optical & Radiological disciplines under Calibration facilities. In the field of Medical Testing laboratories accreditation is granted in Clinical Biochemistry, Clinical Pathology, Haematology & Immunohaematology, Microbiology & Serology, Histopathology, Cytopathology, Genetics, Nuclear Medicine (In-vitro tests only) disciplines. In addition, NABL offers accreditation for Proficiency testing providers & Reference Material producers for which it has APAC and ILAC MRA.

## Benefits of accreditation

NABL is a Full member (ILAC MRA signatory) to ILAC as well as APAC 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.
NABL accreditation is the recognised by various government bodies and regulators. In India, NABL accreditation is usually the precursor to various government/ regulator/ statutory body recognition's.
NABL being a governmental body conducts integrated assessments with regulators such as FSSAI, EIC, APEDA, etc. Integrated assessments simplify the process of recognition, as the laboratory can get accredited and recognized by the regulator in one combined assessment instead of the separate multiple assessments which are usually needed.
