Measurement of diffusion coefficients - Documentation (NT TR 615)

NT TR 615

  • A method to measure diffusion coefficients in plastic films and coatings is described. This method is based on weighing absorbed amounts of water when conditioned samples are exposed to water or water vapour. A similar procedure based on weight loss is also possible. The same method can be also be applied to measuring diffusion coefficients of organic solvents in plastic films and coatings.

Modelling of the radiative feedback from the flames in cone calorimeter (NT TR 540)

NT TR 540

  • The ignition and combustion properties of building materials are often studied using the Cone Calorimeter (ISO5660:1993, NT Fire 048:1993), where the sample is heated by a temporally and spatially constant incident radiative heat flux. After ignition, however, the heat transfer characteristics are changed due to the flame radiation and convection.
