Summary:A flexible high power RF test stand has been designed and constructed at IHEP to test a variety of 500 MHz superconducting RF components for the upgrade project of the Beijing Electron Positron Collider （BEPC ）, such as the input coupler, the higher order modes （HOMs） absorber and so on. A high power input coupler has been conditioned and tested with the RF power up to 250 kW in continuous wave （CW）, traveling wave （TW） mode and 150 kW CW in standing wave （SW） mode. A prototype of the HOMs absorber has been tested to absorb power of 4.4 kW. An introduction of the test stand design, construction and high power tests is presented in this paper.
