Established in 1978 as a nonprofit, public service membership society, A2LA is dedicated to the formal recognition of competent testing and calibration laboratories, inspection bodies, proficiency testing providers, and reference material producers.
A2LA Laboratory accreditation uses criteria and procedures specifically developed to determine technical competence. The criteria are based on the internationally accepted standard ISO/IEC 17025 (which is used for the evaluation of laboratories throughout the world) and other technical program requirements developed with regulators and specifiers. Laboratory accreditation bodies use the ISO/IEC 17025 standard to assess factors relevant to a laboratory’s ability to produce precise, accurate tests and calibration data. These include technical competence of staff; validity and appropriateness of test methods; traceability of measurements and calibrations to national standards; suitability, calibration, and maintenance of test equipment; testing environment; sampling, handling, and transportation of test items; and quality assurance of test and calibration data. Laboratory accreditation to ISO/IEC 17025 covers the same quality management system principles that are addressed in ISO 9001 registration. To ensure continued compliance, accredited laboratories are regularly re-assessed to check if they are maintaining their standard of technical expertise. These laboratories are also required to participate in regular proficiency testing programs (where applicable) as an ongoing demonstration of their competence.
Weas Engineering became A2LA accredited in 2018.
