Annual schemes: Proficiency tests and intercomparisons

On this page the proficiency tests and intercomparison planned to be organized in 2020 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: proftest@environment.fi. Measurements/schemes marked with asterisk (*) are not included in the accreditation scope.

Program for 2021 will be published in October-November 2020 and it will be then available on this page.
