Information about tests
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.

| Needed sample size: | Minimum 2 units |
Standardprüfungen
WVTR package standard 23°C/ 85% rel.humidityStandard test program "Europe" to determine the water vapour permeation of packages. If you need other test conditions, please let us know.
WVTR package standard 38°C/ 90% rel.humidity
Special test program "tropical climate/ asia/ USA" for determination of the water vapour permeation of packages. If you need other test conditions, please let us know.
