It refers to a testing agency that is officially recognized for its quality system and test capabilities in accordance with the requirements of the Framework Act on National Standards and KS Q ISO/IEC 17025.
The system officially recognizes that a recognized body, which adheres to legal or international standards, has the capability to conduct tests in a specific field. This recognition is achieved by requiring a qualified evaluator to assess the quality system and technical capabilities of the testing agency.
Testing is a technical operation in which one or more characteristics of a specific product, process, or service are measured according to a prescribed procedure.
Establishment of an accreditation system in accordance with ISO/IEC 17011 requirements
KS Q ISO/IEC 17025 is recognized through the evaluation of the accredited organization, in accordance with the requirements announced by the head of the accredited organization.
Accredited test (inspection) report service in accordance with various specifications and technical regulations, as recognized.
The test report bearing the KOLAS logo is internationally certified in accordance with international agreements between APAC (Asia-Pacific Accreditation Cooperation) and ILAC (International Laboratory Accreditation Organization Cooperation).
As of 2023, 55 testing agency accreditation bodies from 33 countries have joined the APAC MRA (Mutual Recognition Arrangement), and as of 2021, 104 testing and accreditation bodies from 105 countries have joined the ILAC MRA. These bodies have officially agreed to mutually accept each other's accredited reports.
On June 9, 2010, the Technical Center for High-Performance Valves (Dong-A University Industry-Academy Cooperation) obtained "KOLAS International Accredited Testing Institution Recognition." In December 2022, it further expanded its scope of recognition to provide test services for 18 standards across 6 fields.
