Statement regarding the accessibility of this web site

We try to comply with the Barrierefreie-Informationstechnik-Verordnung (BITV) 2.0, which is the German regulation for accessible information technology. For this, we follow the requirements spelled out in the BITV-Test.

If you have special needs, you can customise the presentation of this website, for example, increase the text size (press Strg+) or choose white text on a dark background (via the browser settings).


Whenever we create new content, we attempt to make sure that all pages use valid HTML. However, no automatic continuous validation of all content is in place. Should you encounter a page which does not validate, please contact us to let us know.

Simple language

The requirement 14.1 of the German regulation for accessible information technology (BITV, Barrierefreie Informationstechnik-Verordung) mandates that each content should be conveyed in the clearest and simplest language possible. We try to follow this requirement by writing our articles and test reports in a way that it can be understood also by users without significant background knowledge. Please contact us if you feel that we have used unnecessarily complicated or ambiguous expressions.


We try not to use abbreviations. The expanded text of abbreviations for organisations or laws will be shown in brackets at their first occurence on a page.
