VDI 4630 (2016-11): Fermentation of organic materials – characterization of the substrate, sampling, collection of material data, fermentation tests: batch fermentation tests and continuous fermentation tests.

Publisher: The Association of German Engineers 

The VDI 4630 standard provides rules and specifications for tests to determine the biogas output of organic materials which serve the interpretation and operational optimisation of biogas plants. Thus, it gives comprehensive and practice relevant support for the determination of the biogas orientation of organic materials. AMPTS^® is recommended as the only automated test apparatus for biochemical methane potential (BMP) tests based on the batch test procedures in this standard.
