The test procedure is essentially the same as procedures dictated by RESNET. The key difference is that guarded testing is explicitly prohibited, as this is a compartmentalization test. The metric is also different as it is based on the entire apartment envelope surface area. For example, a 1,000 ft2 apartment, with 1,000 ft2 of total wall area (party walls and exterior walls), would have a maximum allowance of 900 CFM at 50 Pa.
