2 Terms and definitions
The following terms and definitions apply to this standard. 2.1
Hygroscopicity
The property of fiber materials and their products to absorb and release water vapor in the air. [SC/T5001—1995, definition 19]
Conditioning
The process of placing the sample in a certain atmospheric condition to stabilize the thermal motion of the molecules of the object and to make the absorption and release of moisture close to the dynamic equilibrium state. 3 Requirements
