Abstract：Applying the managed samples used by the First Survey and Design Institute after standardization，the author proceeded experiments on the whole procedure of the gypsum test with the quality control mode. The EDTA capacity method for determining the content of the medium—dissolved salt has been proposed. Compared with the test equipments of the tradi?tional quality method,this method is much simple and applicable for field tests.
