Accreditation to ISO /IEC 17025 can help move your organization toward global recognition, consistent operations, and a competitive advantage. GAAS assessors evaluate the laboratory’s ability to produce precise, accurate test and calibration data. Facilities are regularly reassessed to ensure technical expertise is maintained. We offer accreditation for unique scopes and customized test areas.

ISO/IEC 17025 specifies general requirements for the competence to carry out tests and calibrations, including sampling. It covers testing and calibration quality systems using standard methods and laboratory-developed or modified methods.

The standard consists of general, structural, resource, process, and management system requirements. The general, structural, and management system requirements relate primarily to the operation and effectiveness of the laboratory’s quality management system and the laboratory organization itself. The resource and process requirements include factors that determine the correctness and reliability of the tests and calibrations the laboratory conducts.

Our customers value the skill of our employees and assessors in providing fast and helpful service. GAAS has a 97% customer retention rate and is highly regarded in the accreditation community.
