This International Standard specifies a test method for determining moisture adsorption/desorption properties

of building materials in response to humidity variation. This International Standard also defines the

adsorption/desorption efficiency of building materials, measured as the change in mass of a specimen moved

from a given space to another one of different relative humidity and equal temperature.

Moisture adsorption/desorption properties of materials are measured under conditions of a single cycle and

several cycles.
