Abstract: The surface charging/discharging of space materials will lead contamination to be enhanced heat performance reducd and electromagnetic interference etc.Surface charging and its hurts can be diminished by materials selection,and the evaluating test of space materials charging/discharging characteristics is one of the important factor for materials selection. The main facilities and its principle used in evaluating tests of space materials surface charging/discharging characterristics are introduced.The methods are also given.The testing data indicated that they are in accord with the data from space measurements
