Test criteria
The barrier effect of the encasings against mite faeces allergens is tested using a specially developed stress test. In addition, the biocompatibility (skin and body compatibility) of the material is tested in two cell culture tests. The water vapour resistance and air permeability of the encasing can also be determined.
Test methods
- House dust and mite barrier: testing the permeability of mite faeces allergens through textile surfaces, seams and zippers
- Cytotoxicity test
- Sensitisation test (U-SENS)
- Water vapour resistance
- Air permeability
- Fractional separation efficiency with DEHS test aerosol at 5 cm/s
