1 Scope

This standard specifies the use of humidity reaction method for determination of building materials absorption/release performance of the sample, test equipment, the surface (water vapor) through the wet Resistance settings, test methods, calculations and inspection reports. This standard also defines the suction/desorption efficiency of building materials, passing the sample at the same temperature bar Under the conditions of a relative humidity from the space to another room for different relative humidity changes in quality to determine.

The material's absorption/desorption performance can be measured in a single cycle or in multiple cycles.
