Information about tests
Water Vapour Transmission Rate (WVTR) bottles, packages, moulded parts, tubes, etc. (only suitable for barrier materials, see also "i")
The measurement is carried out by usage of the the water vapor specific hydrolysis- method, which allows to detect even the lowest permeabilities precisely and reproducibly. Besides the offered standard parameters it is also possible to measure under various different 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, PLA cannot be measured due to excessive permeation.
| test method: | permeation |
| Norms: |

| Needed sample size: | min 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.
