This Standard 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 μm sieve (see Clause 9 Note 1).
The method as described is applicable if —
(a) more than 10 % of the material passes the 75 μm sieve as measured in AS 1289.3.6.1; and
(b) only an ASTM 152H hydrometer conforming to ASTM E100 is used. A method for calibrating an hydrometer is set out in Appendix B.
