-
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 30 days to 7⿿9 days.
-
The recommended initial equilibrium period is 12⿿16 h, shorten from 48 h.
-
The recommended flow rate is 36 mL/h which is three times that specified in ISO/TS 21268-3.
