摘要

Based on latest research and experiments on water seal, this paper contains thorough analysis on worldwide technologies and philosophies concerning maximum water drainage capacity of drainage riser in buildings.Objections are brought forward against existing Assessment Criteria, for instance, "internal pressure fluctuation below ± 40 mmH20" , "water seal loss depth not exceeding 25 mm" and etc.The paper proposed a new testing philosophy that testing on the maximum water drainage of drainage riser in buildings should comply with the pressure characteristic pattern of water seal, and vacuum suction of drainage system prior to positive pressure confirmation, and positive calibration after testing.
