Tests of this standard

Water vapour transmission rate (WVTR) plastic films, laminates, coated papers and aluminium foils
Measurement is performed using the water vapor specific hydrolysis method. Usually deviating from the standard as a double determination.


Water Vapour Transmission Rate (WVTR) of moulded parts, packages, pouches, bottles, etc. (only suitable for barrier materials, see also "i")
The measurement is carried out by using the the water vapor specific hydrolysis method, which allows to detect even the lowest permeabilities precisely and reproducibly. Besides the standard parameters offered, measurements can be carried out under a wide variety of temperature and humidity conditions. Attention: This method is only suitable for packs with a good water vapour barrier. Materials with high permeation coefficients, e.g. PA, thermoplastic starch or PLA, cannot be measured due to excessive permeation.


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).
