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. The test basis was the DLG test frame for reernate-free and reernate-containing silo films made of low-density polyethylene (PE-LD) with and without barrier shifts, as of November 2016. No other criteria were examined.
