About ISO 17025 Laboratory Accreditation
ISO/IEC 17025 is the main standard used by testing and calibration laboratories. There are two main sections in ISO/IEC 17025 - Management Requirements and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the quality management system within the laboratory. Technical requirements address the competence of staff, methodology and test/calibration equipment. Laboratories use ISO/IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. Since the standard is about competence, accreditation is formal recognition of a demonstration of that competence.

About L-A-B
Laboratory Accreditation Bureau was established to provide laboratory accreditation services to independent and captive, testing and calibration laboratories across North America. Laboratory Accreditation Bureau is a signatory to the Asia Pacific Laboratory Accreditation Cooperation (APLAC) Mutual Recognition Arrangement (MRA) effective December 6, 2007.
