This European Standard defines the test method to be used to determine the air permeability of completely assembled windows and doorsets of any material, when submitted to positive or negative test pressures. This test method is designed to take account of conditions in use, when the window or doorset is installed in accordance with the manufacturer’s specification and the requirements of relevant European Standards and codes of practice. This European Standard does not apply to the joints between the window or doorset frame and the building construction.
