Air Permeability Testing

We perform to air permeability test with static pressure for determine the air leakege value of the system.Static pressure difference which is identified according to the project specification is applied to the testing location and the air leakage value is measured according to ASTM E 783. The air permeability of the whole or some part of a building according to the EN ISO 9972 standard. 50 Pascals of pressure difference is applied on the system to be tested with a special fan, and the air leakage value is measured as m³ / hr. Measurement result is compared with the limits which is defined by the related standard and directives.
