ASTM D1505 The density of Plastics by the Density-Gradient Technique

The standard method ASTM D1505 determines the density of plastic materials. This test method involves measuring the level to which a test specimen sinks in a liquid column exhibiting a density gradient. The values expressed in SI units should be considered as standard.

    Scope:

    The standard test method, Density of Plastics by the Density-Gradient Technique ASTM D1505, determines the density of plastic materials. This test procedure is intended to produce findings that are accurate to within 0.05 percent. The density of a solid is a readily quantifiable attribute that is widely used to track physical changes in a sample, as a measure of sample uniformity, and as a means of identification.

    Test Procedure:

    In ASTM D1505 testing, wet specimens are placed in tubes and are required to reach equilibrium. Then thin films are required to settle, and the height of the specimens is measured by a cathetometer; after that, the samples are removed by means of a clock motor. The procedure should be performed at a low rate so that the density remains undisturbed.

    Specimen size

    Specimen thicknesses should range from 0.025 to 0.051 mm (0.001 to 0.002 in.).

    Data:

    The following formula is used to calculate density in ASTM D1505 testing:

    Density at x = a +[(x – y)(b – a)/(z – y)]
    where:
    a and b = densities of the two standard floats
    y and z = distances of the two standard
    x = distance of unknown above the same arbitrary level

    Conclusion:

    The standard test method, Density of Plastics by the Density-Gradient Technique ASTM D1505, determines the density of plastic materials.
