Standardprüfungen

WVTR / Sd value water vapour barrier materials
Determination of the SD value (water vapor diffusion equivalent air layer thickness) of building materials and products that are used as vapor barrier, electrolytic measurement according to ISO 15106-3 (suitable for Sd-values in the range of approx. 50 - >1500 m).


WVTR/ Sd- value breathable materials
Determination of the Sd- value (water vapor diffusion equivalent air layer thickness) of building materials and products, which used as permeable (breathing) materials, gravimetric measurement according to DIN EN ISO 12572 / DIN EN 12086 (suitable for Sd-values in the range of approx. 1 - 100 m).
