Abstract

Several studies confirmed that the uncertainty of fan pressurization measurements could not be neglected. This implies that the most common regression technique, the ordinary least square (OLS) method, might not be appropriate for fan pressurization measurements. The present study investigated alternative regression method, weighted line of organic correlation (WLOC). Results showed that the difference in airtightness characteristic value was significant according to the regression method when the uncertainty of the measured values was high, such as under conditions of low pressure difference or high wind speed.
