Describes a procedure for determination of moisture absorption properties in the through-the-thickness direction for solid materials in flat or curved form. Also describes procedures for determining the amount of water absorbed by plastic specimens with precisely defined dimensions exposed to precisely defined conditions where test specimens are immersed or subjected to humid air. The calculation of the through-the-thickness moisture diffusion coefficient assumes a single-phase Fickian material with constant moisture absorption properties through the thickness of the test specimen. This model is typically valid for homogeneous materials and for reinforced polymer matrix composites tested below their glass transition temperature, although some two phase matrices such as toughened epoxies may require a multi-phase absorption model, which is not covered by this standard.
