DRRR – Proficiency testing / round robin
As an accredited provider of proficiency testing / round robin with over 15 years of experience, we offer you high-quality proficiency tests in a wide range of testing and analytical areas. The focus is on the areas of food, consumer goods, material testing and microbiology, as well as medical devices. A detailed overview of the proficiency testing schemes offered can be found either in our online system (ODIN) or via the catalogs in the navigation menu on the left.
For the development and execution of our proficiency tests, we combine statistical know-how with corresponding technical competence. In this way, the specificity of individual parameters can already be taken into account in the design of the proficiency test. In this way, we also ensure that the intended statistics always match the data of the examination / test.
