A method to quantify uncertainties in airtightness measurements: Zero-flow and envelope pressure

•Multi-level model should be used to estimate uncertainties in zero-flow pressure.•Zero-flow pressure approximation leads to substantial uncertainties.•Uncertainties can be reduced by increasing the measurement period for zero-flow pressure.•Uncertainties in zero-flow pressure lead to a change in re...
