Duration of the walk test:
The voltage charge is measured when the test person touches the floor
covering with both feet.
Floor coverings are considered to be antistatic when the voltage charge
does not rise above 2000 V (definition according to Memorandum EDV
1, issued 7/84 by the TFI of Aachen for Carpets).
One minute (shuffling ones feet) at 23ξC and at 25% relative humidity.
For the material of the soles, a special rubber material is used from the
German Federal Materials Testing Institute.
This material is slightly conductive, offering a resistance of approximately
109 . between the test person and a conductive floor.
