The Korea Laboratory Accreditation Scheme(KOLAS) is the governmental accreditation body established on December 8, 1992 and administered by the Korean Agency of Technology and Standards(KATS). The KOLAS Secretariat, which is responsible for the day-to-day running of KOLAS is currently operated by the Conformity Assessment Division for accreditation of testing, calibration laboratories and inspection bodies. The division belongs to the Bureau of Conformity Policy of KATS and the Administrator of KATS represents KOLAS externally.

KOLAS has been actively participating in the international activities relating to testing and calibration in corporation with the Asia-Pacific Laboratory Cooperation(APLAC) and the International Laboratory Accreditation Cooperation(ILAC). KOLAS signed Asia-Pacific Laboratory Cooperation Mutual Recognition Arrangement(APLAC MRA) in Sydney on October 23, 1998 for testing and May 22, 2001 for calibration. Since then, members of the APLAC MRA have expanded to 27 ones from 17 economies. KOLAS is also a signatory to the International Laboratory Accreditation Cooperation Mutual Recognition Arrangement (ILAC MRA) which was signed in Washington DC on November 2, 2000. It now involves 73 member bodies from 61 economies. The ILAC arrangement will provide technical underpinning to international trade by promoting cross-border stakeholder's confidence and acceptance of accredited testing and calibration results.
