1. Airflow values calculated assuming a linear relationship between volumetric airflow and differential pressure.
2. Water flows measured after prewetting with alcohol and calculated assuming a linear relationship between flow and differential pressure.
3. Bubble points for 0.2 µm, 0.45 µm, and 3.0 µm pore sizes measured using IPA; all others measured using ethanol.
NT = Not tested.
