  • Internationally Accredited Testing Laboratory.

    Overview of Korea Laboratory Accreditation Scheme (KOLAS)

    • KOLAS is Korea’s accreditation system in place to recognize the technical competence of testing and calibration laboratories
      for those who meet the requirements of international standards of ISO/IEC 17025.
    • Having joined in MRA’s (mutual recognition arrangements) of the relevant international organizations, such as ILAC
      (International Laboratory Accreditation Cooperation) and APLAC (Asia-Pacific Laboratory Accreditation Cooperation),
      KOLAS participates in wide areas of international proficiency testing activities.
    • Being a signatory to the relevant international MRA’s, the testing reports issued by KOLAS accredited laboratories
      are accepted all over the world.

    Benefits of services offered by KOLAS testing laboratories

    • Testing reports issued by KOLAS accredited testing laboratories are accepted to be valid everywhere in the world as it is in line with the WTO’s TBT (Technical Barriers to Trade) Agreement. It allows industries to overcome technical barriers of some advanced countries.
    • The principle of “One Test, Accepted Everywhere” in practice in global markets creates benefits of lower cost and faster flow of goods by avoiding unnecessary duplicate testing in international trade.
    • Testing reliability can be raised by using the internationally recognized testing reports which leads to the improvement of the quality of products and the reduction of cost.
    • Accuracy needs for the improvement of product's performance can be assured.
    • Internationally recognized testing reports can be used as the basis for the legal requirements of health, safety and environmental protection are fulfilled.
    • Internationally recognized testing reports leads to the improvement of enterprise’s image and the easy acquirement of supplier’s competence.

    Accreditation Scheme of KOLAS

    Based on the “Framework Act on National Standards,” KOLAS was established in December 1992 as a governmental accreditation body under the administration of the Korea Agency of Technology and Standards (KATS). KOLAS has ever since made its effort in developing the nation’s laboratory accreditation system that could be in compliance with the international standards. KOLAS takes an important part in international community by becoming a signatory to international MRA’s of APLAC in October 1998 and that of ILAC in November 2000, respectively.
