This study, Using Pusan clay, examined a relationship between Dynamic and Static Liquid Tests. The Static Liquid Tests were carried out based on BS and JIS. The results of the study are summarized as follows. (1) The result of the Dynamic Liquid Limit Test showed that the liquid limit values of Natural condition soil were greater than those of oven-dried soil by 4%~15%. (2) The liquid limit value of the Static Liquid Limit Test was greater than that of the Dynamic Liquid Limit Test by 2%~9%. The following equations show the relationship between tile two values. WL, Fall(JIS)=0.961/WL, Cas+4.209, WL, Fall(BS)=0.969/WL, Cas+5.024, (3) The liquid limit value of BS was greater than that of JIS by 1%~6%. The following equation shows the relationship between the two values. WL, Fall(BS)=0.976WL, Fall(JIS)+2.638
