The circular test specimen is placed on the opening of a test bottle filled with a certain amount of solid desiccant in a water vapor permeation testing machine. This setup isolates the desiccant inside the bottle from the air outside. By operating the water vapor permeation testing machine, the test bottle rotates and the fan stirs the air, causing the desiccant to continuously absorb water vapor passing through the test specimen. The water vapor absorbed by the desiccant over a specific period is measured by weighing the test bottle, which helps assess the water vapor permeation performance of the material.
