Order a hard copy. WHAT IS A PERM RATING? If a material has a perm rating of 1.0, 1 grain of water vapor will pass through 1 square foot of the material, provided that the vapor pressure difference between the cold side and the warm side of the .
The “dry cup” method involves utilizing a desiccant within the test cup and maintaining 50% RH in the ambient chamber. Water vapor is expected to diffuse into the cup (i.e., the cup’s mass will increase over time), and the mass recorded is essentially the water vapor absorbed by the desiccant.
The inside of the wet cup is near 100% relative humidity (a higher vapor pressure than the chamber), and the inside of the dry cup is near 0% (a lower vapor pressure than the chamber). Physics being physics, the wet cup will lose water vapor and the dry cup will gain water vapor. Five testing instruments plus a new test apparatus were employed to evaluate the water vapor transport properties of fabrics with low, medium, and high vapor permeability. The test results show that the desiccant inverted cup method generated the highest water vapor transmission rate, followed by the new method, the dynamic moisture permeation .No.318 WATER VAPOR PERMEABILITY CUP JIS (K5400), K6549, Z0208, TAPPI-T448, T464, ISO 2528 Specification Specifications are subject to change without notice.
