VDI 4630 (2016): Fermentation tests – Batch procedures

VDI-Standard: VDI 4630

The Association of German Engineers (2016)


The VDI 4630 standard provides rules and specifications for tests to determine the biogas output of organic materials which serve the interpretation and operational optimization of biogas plants.  Thus, it gives comprehensive and practice relevant support for the determination of the biogas orientation of organic materials.

The standard defines essential terms to avoid misunderstandings.  It presents approaches to the reader which allow a comprehensive characterization of all organic substances used in practice.  A common procedure is suggested for the sampling and sample preparation.  Information is provided on the preconditions of how and which data on substrates are measured and what should be considered particularly.   Furthermore, it describes the procedure for the execution of batch and continuous tests.  It finally offers corresponding forms for a clear representation of the results.


Our flagship product series, Automatic Methane Potential Test System (AMPTS), are recommended as automated test apparatus for batch test procedures in VDI 4630 (2016).
