Hygrothermal performance of building materials and products — Determination of hygroscopic sorption properties ISO 12571:2021

General information

60.60 Standard published   Nov 8, 2021

ISO

ISO/TC 163/SC 1 Test and measurement methods

International Standard

91.100.01   Construction materials in general

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.
