National Accreditation Board for Testing and Calibration Laboratories (NABL)


The National Accreditation Board for Testing and Calibration Laboratories (NABL) is the national accreditation body of India responsible for the accreditation of testing and calibration laboratories, as well as proficiency testing providers. Established in 1999, NABL operates under the Department of Science and Technology, Government of India. Its primary role is to ensure that laboratories meet international standards of competence, accuracy, and reliability, thereby fostering confidence in the quality and safety of products and services across various industries.

NABL collaborates extensively with national and international organizations to maintain high standards of accreditation. It is a full member of the International Laboratory Accreditation Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC). Through these memberships, NABL participates in mutual recognition arrangements that facilitate the global acceptance of test and calibration results issued by accredited Indian laboratories. These international collaborations help reduce technical barriers to trade and enhance the integration of Indian products and services into the global market.

To uphold its mission, NABL continuously updates its accreditation criteria and processes to align with international best practices. It provides essential services including the accreditation of testing and calibration laboratories, proficiency testing providers, and reference material producers.
