Scope

This document specifies two alternative methods for determining hygroscopic sorption properties of porous building materials and products:
a) using desiccators and weighing cups (desiccator method);
b) using a climatic chamber (climatic chamber method).
The desiccator method is the reference method.
This document does not specify the method for sampling.
The methods specified in this document can be used to determine the moisture content of a sample in equilibrium with air at a specific temperature and humidity.
