WebOne must find “good” and “bad” solvents. The definition of good can vary from swelling to totally soluble, from suspension of particles (pigments, fibers) for long times versus rapid settling, to rapid permeation through protective gloves to good protection, that is, no permeation. All of these tests have been used to assign HSP.

In physics and engineering, permeation (also called imbuing) is the penetration of a permeate (a fluid such as a liquid, gas, or vapor) through a solid. It is directly related to the concentration gradient of the permeate, a material's intrinsic permeability, and the materials' mass diffusivity. Permeation is modeled by equations such as Fick's laws of diffusion, and can be measured using tools such as a minipermeameter. Web8. mar 2000 · Ion permeation through the “model selectivity filter” was modeled with a reduced set of functional groups representative of the constituent amino acid side chains. Force-field minimizations were conducted to obtain the energy profile of the cations as they get desolvated and bind to the “model selectivity filter.”
