APPARATUS AND METHOD FOR TESTING SEALED GLAZING UNITS

摘要

An apparatus for measuring the gas diffusion rate from a sealed glazing unit (2) comprises at least one cassette (1) with a known inner volume and adapted for containing a sealed glazing unit (2) with a known volume so that a free rim volume exists along the periphery of the glazing unit in the cassette. The cassette (1) is provided with at least one gas inlet (7) and at least one gas outlet (8) which can be connected to a gas chromatograph.
