have an air leakage less than 0.00030 Specific Leakage Area(SLA)when tested with a blower door at a press of 50 Pascals
(0.2 inch w.g.).Testing shall occur at any time after rough in and after installation of penetrations of the building envelope,
including penetrations for utilities, plumbing, electrical,ventilation,and combustion appliances and sealing thereof.When
required by the building official,the test shall be conducted in the presence of department staff. The blower door test results

2.Once visual inspection has confirmed the presence of a gasket(see Section 502.4),operable windows
and doors manufactured by small business shall be permitted to be sealed off at the frame prior to the test.
