Abstract
A particle filter for an internal combustion engine, in particular a soot particle filter, can be tested. The filter is subjected at the inlet side to a hot gas flow which is laden with particles. The particles are supplied to the hot gas flow from a particle storage container by means of a dosing device. The quantity of particles which is introduced into the hot gas flow during a predefined measurement time period is determined by weighing the particle storage container. There is also provided a configuration for carrying out the method.
