Abstract
⿢Ways to reduce the duration of column percolation tests specified in ISO/TS 21268-3 were proposed.⿢Four equilibrium periods and two flow rates on four different soils were tested.⿢The time to perform column percolation tests can be shortened from 20 to 30days to 7⿿9 days.⿢The recommended initial equilibrium period is 12⿿16h, shorten from 48h.⿢The recommended flow rate is 36mL/h which is three times that specified in ISO/TS 21268-3.
