    WK65304

    1. Scope

    1.1 This test method covers the quantitative determination of the distribution of particle sizes of the fine-grained portion of soils. The Integral Suspension Pressure (ISP) method is used to determine the particle-size distribution of the material that is finer than the No. 200 (75-micron) sieve and larger than about 0.2-micron. The test is performed on material passng the No. 10 (2.0-mm) or finer sieve and the results are presented as the mass percent finer versus the log of the particle diameter.

    Rationale

    New methods are being developed to quantify particle size analysis. The ISP method reduces human error and help increase the accuracy of measuring particle size distribution. The new methods also reduce the amount of labor needed to make these measurements.

    The title and scope are in draft form and are under development within this ASTM Committee.
