Everything you should know about NABL India

National Accreditation Board for Testing and Calibration Laboratories (NABL), a Constituent Board of Quality Council of India has been established with the objective of providing Government, Industry Associations and Industry in general with a scheme of Conformity Assessment Body’s accreditation which involves third-party assessment of the technical competence of testing including medical and calibration laboratories, proficiency testing providers and reference material producers.

NABL is Mutual Recognition Arrangements (MRA) signatory to International Laboratory Accreditation Co-operation (ILAC) as well as Asia Pacific Laboratory Accreditation Co-operation (APLAC) since 2000 for the accreditation of Testing and Calibration Laboratories (ISO/IEC 17025), Medical Testing Laboratories (ISO 15189), Proficiency Testing Providers (PTP) (ISO/IEC 17043) and Reference materials producers (RMP). Such MRA reduces the technical barrier to trade and facilitates acceptance of test/ calibration results between countries that MRA partners represent. NABL provides voluntary accreditation services to:

● Testing laboratories in accordance with ISO/ IEC 17025 ‘General Requirements for the Competence of Testing and Calibration Laboratories’
● Calibration laboratories in accordance with ISO/ IEC 17025 ‘General Requirements for the Competence of Testing and Calibration Laboratories’
● Medical testing laboratories in accordance with ISO 15189 ‘Medical laboratories -Requirements for quality and competence’
● Proficiency Testing Providers (PTP) in accordance with ISO/IEC 17043 “Conformity assessment — General requirements for proficiency testing” and
● Reference material producers (RMP) in accordance with ISO 17034 “General requirements for the competence of reference material producers.”
