The certification mark

The DLG QUALITY SEAL for operating equipment and consum­ables encompasses products, which are subjected to extensive testing of their value-determining and advertised characteristics. The tested criteria and the requirements to be fulfilled are specified by independent commissions and are designed – over and above legal requirements – to prove the product’s fitness for purpose, its advertised characteristics and practical requirements. Testing contents and requirements are ­deve­loped further by the responsible specialist departments of the DLG e.V. in line with the applicable legis­lation, as well as with technical and scientific progress. Successful testing is concluded with the assignment of the DLG QUALITY SEAL. The approved products are then published. The DLG quality seal test included technical measurements in the laboratory and practical assessments. The test basis was the DLG test framework for Straw protection fleece made of continuous polypropylene fibres and a basis weight of 140 g/m², as of February 2022.
