DLG QUALITY SEAL: "Continuous Monitoring"

Download printable Version

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. Other criteria were not investigated.

Test results

The round bale winding net HayFIL tested here was tested in the DLG quality seal test on test benches and in the ­laboratory for mechanical, physical and aging properties and measured the running length. In the practical investigations, the handling was assessed. The net is designed for the mechanical winding of bales made with round bales for silage pre­paration, hay and straw.
