PURPOSE: A device for testing a lifetime of a ceramic disk for a water valve is provided to accurately evaluate a life time of a ceramic disk before a release through quantitively analyzing by performing a quantitive life time test of the ceramic disk according to testing steps set in advance in an acceleration environment. CONSTITUTION: A device for testing a lifetime of a ceramic disk for a water valve comprises a base(10), a test module(12), a lever driving module(14), and a stand(16). The test module comprises a jig(22), a cartridge(24), and a lever(26). The jig is installed on the base. The cartridge utilizes a ceramic disk(28) for a test and hot water and cold water are supplied to. The lever drives the ceramic disk, thereby controlling amounts of the hot water and cold water. The lever driving module arranged in the upper part of the test module comprises a lever plate(70) where an end part of the lever is joined to. A stand loads the lever driving module, thereby controlling a setting of the lever driving module to a test position.
