Organised by the German Society for Fat Science (DGF).
Interlaboratory comparison tests serve laboratories to check applied methods and to recognize systematic errors. They are a central part of every quality assurance system. The DGF herewith announces the 26th ringtest for fat analysis to be carried out in 2020.
32 parameters can be tested this year:
(The list of parameters is still preliminary and may be subject to change!
The list is final once this hint is removed)
Vegetable Oil, Olive Oil and a Used Deep-Frying Oil. (150g each, can be doubled on request)
Each laboratory may choose an individual set of parameters from the list above.
The execution and the evaluation of the laboratory comparison test are carried out according to the internationally recognized recommendations "Proficiency Testing Of Laboratories" of Codex Alimentarius and ISO.
