The Soil Mechanics Laboratory of the Division of Building Research has used a 1-point liquid limit procedure for most routine tests since 1955. The decision to use the shortened method was based on a statistical study of 390 previous tests made by the 3-point method. This paper reviews the analysis of the test records available to the author along with the results of three other independent investigations on 1-point methods. After considering the variability which can be expected in the liquid limit test, the conclusion is reached that no additional significant errors are introduced through a 1-point method. A detailed 1-point test procedure is appended to the paper.
