DLG e.V. - Test standards and test commissions

Test standards and test commissions

The methods, test profiles and standards that are applied by the DLG Test Center were developed independently of manufacturers and are based on state-of-the-art measuring and test methods. The test frameworks that are applied by the DLG are developed by our own commissions that are made up of farmers, scientists, representatives from various associations and consultants as well as national and local governments plus DLG test engineers. A test framework reflects the current state-of-art and applies objective and recognised methods for reproducible results.
