摘要： PROBLEM TO BE SOLVED: To provide a method capable of evaluating the water absorption characteristics of a sample with satisfactory reproducibility, moreover regarless of the shape, grain sizes, density, or the like of the sample, in which measuring work is simple and individual differences hardly occur. SOLUTION: A prescribed amount (known weight) of foamed grains, before absorbing water and water are inserted in a container capable of strictly adjusting capacity for bringing the inside of the container into a state filled with them up to a prescribed level. Then the total weight is measured immediately. After a prescribed time has a elapsed, water is added again, to bring the inside of the container into a state filled up to the prescribed level, and the total weight is measured. The difference between both the total weights is taken as the amount of water absorbed by the foamed grains of a prescribed amount (known weight) and the water absorption charactersitics of the foamed grains are evaluated.
