This document specifies test methods for assessment of the moisture activity of any kind of mineral substrate prior to the installation of levelling compounds and/or floor coverings or parquet floors bonded with adhesives. The methods are independent from mineral substrate chemical composition or materials and applicable with commercially available equipment.
This document is not applicable to loose lay installations.
The measurement of the moisture content of mineral substrates according to EN 13813 is described in EN 1264-4.
