ASTM D5229 testing provides a variety of procedures in order to determine the moisture absorption or disorption properties. This is a gravimetric test that monitors the change in moisture content over time.
There are several procedures that are discussed throughout this method. Procedure A covers the determination of the two Fickian moisture diffusion material properties, the moisture diffusitivity constant and moisture equilibrium content. This procedure will result in the diffusivity constant, Dz and the moisture equilibrium content, Mm at the given moisture exposure level and temperature. Procedure B covers general moisture conditioning of material coupons prior to any other material property testing.
Procedure C covers the conditioning of material coupons to a nominal relative humidity level of 50% prior to any other material property testing.
Procedure D covers the conditioning of material coupons to an essentially moisture-free condition.
