HOW DO LABORATORIES BECOME ACCREDITED?
Laboratories can have either all or part of their testing and calibration activities accredited. The accreditation process involves a thorough evaluation of all the elements of a laboratory that contribute to the production of accurate and reliable test data. The evaluation process can take one to several days, and involves the use of specialist technical assessors who evaluate the specific types of testing or measurement being performed. The assessment criteria are based on the international standards ISO/IEC 17025 or ISO 15189, which are used for evaluating laboratories throughout the world. Laboratory accreditation bodies use this standard specifically to assess factors relevant to a laboratory’s ability to produce precise, accurate test and calibration data, including the: • 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 •
