Building Regulations – Conservation of Fuel and Power Part L state that the air tightness of a building, known as ‘air permeability’ or leakage rate, should not exceed 10 m3 per hour per square metre of the building envelope. All new buildings over 1000 sqm gross floor area have required a mandatory test for ...
In this study, a triaxial confinement chamber and mass flow meter were used to measure the air permeability of compacted clayey sand specimens. Specimens were extracted at different angles with respect to the vertical direction to measure the anisotropy. ...
Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability ...
