    Ring tests

    Organic products contain about 100 times less pesticides than conventional procuts. It is most important for Organic products to detect and quantify these typically very small amounts. Therefore BNN ring tests focus on levels around BNN Orientation Value of 0,01 mg/kg. This demands good laboratory equipment, much experience and best care.

    As open ring test are previously anounced, laboratories do not work under routine conditions: they will be especially well prepared and take extra time. Therefore BNN has established its own ring tests without advance notice or they are even disguised ring tests.
