This British Standard describes a method for the determination of the water vapour transmission rate of thermoplastics material in the form of film which can be heat-sealed, where the water vapour transmission through the seal is known to be considerably less than through the film. The method is suitable for testing materials of water vapour transmission not less than 1 g/m2 per day.
