AS 12126.96.36.199:2020 Methods of testing soils for engineering purposes Part 3.6.3: Soil classification tests 一Determination of the particle size distribution of a soil – Standard method of fine analysis using a hydrometer.
AS 12188.8.131.52 sets out a method for the quantitative determination of the particle size distribution in a soil from a coarse sand size down, using an hydrometer for particles finer than the 75 pm sieve (see Clause 9 Note 1).
The method as described is applicable if— more than 10 % of the material passes the 75 pm sieve as measured in AS 12184.108.40.206; and
only an ASTM 152H hydrometer conforming to ASTM E100 is used. A method for calibrating
an hydrometer is set out in Appendix B.
