Annual program: Proficiency tests and intercomparisons

On this page the proficiency tests and intercomparison planned to be organized in 2024 are listed. For each scheme the sample delivery time is informed. Approximately 2 months prior that, more information for the test will be available and also the registration opens. More information is given on page Current proficiency tests, you may also contact us: Measurements or schemes marked with asterisk (*) are not included in the accreditation scope.

Program for 2025 will be published in October-November 2024 and it will be then available on this page.
