Reliable, reproducible testing of filter media is important for the development and optimisation of filter media, as well as for quality assurance during the production process. Filter materials for dust filters for gases are characterised by a reference test method according to the ISO 11057. Under standardised test conditions and test procedures both the performance during operation and the particulate emissions of the filter media are determined in order to obtain information about the operation and separation behavior during practical use.

The most interesting parameters for the characterisation of filter media are:

- differential pressure behavior during the dust loading
- the gravimetric separation efficiency
- the fractional filtration separation efficiency
- the loading capacity of the filter
- the cyclic behavior at aging of the filter

With the AFC 133 Filter Media Test Stand customised test procedures can be done as well.
