Tests of this standard

Water vapour transmission rate (WVTR)/ Sd- value (water vapour diffusion-equivalent air layer thickness)
Determination of the Sd value according to the gravimetric method on diffusion open and diffusion inhibiting materials with Sd values of approx. 0.03- 10 m ( equivalent to a WVTR of approx. 4- 800 g/(m²xd) depending on the material and test conditions) as a quintuple determination. For diffusion-inhibiting, diffusion-blocking and diffusion-proof materials with Sd values of approx. 10- >1500 m (corresponds to a WVTR of approx. 0.005- 125 g/(m²xd) depending on the material and test conditions), we recommend the more rapid and more cost-effective electrolysis method (then deviating from the standard as a double determination).

Water vapour transmission rate (WVTR), gravimetric test
Gravimetric determination of WVTR. We recommend the measurement by hydrolysis method acc. ISO 15106-3 (hist DIN 53122-2). If you have any questions, please do not hesitate to contact us.
