The International Organization for Standardization (ISO) sets the international standards for laboratories that conduct tests and calibrations, as well as sampling. ISO 17025 certification offers a tangible way to guarantee to clients that a laboratory meets the requirements to successfully manage all aspects of sampling and testing.
The certification proves that a laboratory is competent in its technical tests/calibrations and is operating according to the ISO management guidelines. Obtaining the accreditation requires an extensive audit process of several different technical functions of the lab, including test and calibration methods, sampling, and handling of test results. Every lab function related to the test being considered for certification must be documented and maintained as part of this process.
