The study was conducted in accordance with the PN-EN ISO 12571 standard. Automated techniques employing moisture-generating devices, such as Dynamic Vapor Sorption (DVS), offer an alternative to traditional methods for determining sorption isotherms. The automated DVS method utilizes instrumentation capable of precisely controlling and generating air humidity.Equilibrium time was determined by continuously monitoring the specimen’s mass change over time (dm/dt). When the rate of mass change approached zero, the instrument automatically advanced to the subsequent relative humidity level. Testing was performed at a constant air temperature of 20°C, with relative humidity varied incrementally from 0% to 97% in approximately 10% steps. At each step, once the rate of mass change fell below 0.0005% per minute, the system adjusted the humidity to the next level.Prior to testing, all specimens were dried to constant mass at 40°C.
