ASTM B311 Density of Powder Materials Containing Less Than Two Percent Porosity

ASTM B311 is used for determining the density of powder metallurgy (PM) materials having less than two percent porosity and cemented carbides. This test method works on Archimedes’ principle. The end results are reported as the density rounded to the nearest 0.01 g/cm³.... Read More

    Scope:

    ASTM B311 is used for determining the density of powder metallurgy (PM) materials having less than two percent porosity and cemented carbides. This test method works on Archimedes’ principle. ASTM B311 is not applicable for materials with unsealed surface porosity that may absorb water making the observed density values higher than the real value.

    Test Procedure:

    For ASTM B311, the test sample is first weighed in air and then in water using an analytical balance. Finally, the density is calculated using Archimedes’ principle.

    Sample size:

    The test samples are used as specified by ASTM B311. 

    Data:
    In ASTM B311, the density is calculated as follows:

    Density (D) = Mass /Volume = D = (AE)/(A-B+C)=(AE)/(A-F)

    where:

    D = density of the test sample, g/cm3,

    A = mass of the test sample in air, g,

    B = apparent mass of the test sample and sample support in water in,g

    C = mass of the sample support immersed in water in, g

    F = mass of test sample in water with a mass of the sample support tared, (g), and

    E = density of water in g/cm3

    Conclusion:

    ASTM B311 is used for determining the density of powder metallurgy (PM) materials having less than two percent porosity and cemented carbides.
