Water vapour transmission


Water vapour transmission rate:

The standard specifies a method for determining the water vapour transmission rate of plastic films, sheets, even if they have one or multi-layer structures.

  • MSZ EN ISO 15106-2:2005
  • ASTM F 1249:2006

Water vapour transmission properties of cellular plastics:

This standard specifies a method of determining the water vapour transmission rate, water vapour permeance, water vapour permeability and water vapour diffusion resistance index for rigid cellular plastics, if they have thicknesses from 10 mm upwards, and may contain natural skins or adhered facings of some different material.

  • ISO 1663:2007
