EN ISO/IEC 17025:2018 is an international standard that specifies the requirements for a competence and accreditation system for laboratories. It ensures that laboratories operate to appropriate standards of quality and competence to ensure that the results of testing, calibration and analysis are reliable and relevant. This standard includes requirements for laboratory personnel, documentation, processes and resources, as well as for the process and control of testing, calibration and analysis. This standard is applicable to any organisation that performs testing, calibration or analysis, whether it is a public, private or non-governmental organisation. It helps to ensure that laboratory results are reliable and relevant and that laboratories are competent in their fields.
