Dear Partners,

Based on the feedback we have received, in addition to our accredited annual program, we plan to introduce further proficiency tests, with a primary focus on sampling activities.
The planning and organization of the following proficiency tests for 2026 has already begun for the following proficiency tests.

These items are currently under planning, and the results of preliminary studies as well as the applicable parameters will determine whether each test can be organised as an accredited or non-accredited proficiency test.

The announcement about these PT schemes and their design, timelines and fees will be announced once the developments are finalized. Our partners will be notified by e-mail, but the information will also be published here on the website.
