From 2018 IECC: R402.4.1.2 Testing.
The building or dwelling unit shall be
tested and verified as having an air
leakage rate not exceeding (3.00 ACH50)
three air changes per hour in Climate
Zones 3 through 8. Testing shall be
conducted in accordance with
RESNET/ICC 380, ASTM E779 or ASTM
E1827 and reported at a pressure of 0.2
inch w.g. (50 Pascals). Where required
by the code official, testing shall be
conducted by an approved third party. A
written report of the results of the test
shall be signed by the party conducting
the test and provided to the code official.
Testing shall be performed at any time
after creation of all penetrations of the
building thermal envelope. Building
