The type of testing that may assume the flow exponents based on the conditions of the test is single-point testing. In single-point testing, measurements are typically taken at one pressure level, which allows the tester to calculate airflow at that specific point. When conducting this type of test, the assumption of the flow exponent can be applied based on known conditions such as building type, configuration, and historical data associated with similar structures. This assumption can simplify analysis but may not capture the full range of airflow characteristics of the building.

Multi-point testing and two-point testing, on the other hand, involve taking measurements at multiple pressure points or two distinct pressure levels, respectively. This approach provides a more comprehensive analysis of the building's airtightness by determining both flow rates at varying pressures, thus reducing the reliance on assumptions about flow exponents. Continuous monitoring involves ongoing measurements over time and would not typically involve a singular assumption of flow exponents as it seeks to assess variations in airtightness on a continual basis.
