Millimetre per Second At 200 Pa (mm/s @200 Pa)
Air permeability in mm/s at 200 Pa, the ISO 9237 condition used for industrial and filter fabrics. As a permeance it is 5 µm/(Pa·s) per mm/s.
Symbol: mm/s @200 Pa
Quantity: air permeance (air flow per unit area per unit pressure difference)
SI relation: 1 mm/s @200 Pa = 5 µm/(Pa·s)
Derivation: 1 mm/s ÷ 200 Pa = 5 × 10⁻⁶ m/(Pa·s) = 5 µm/(Pa·s).
Exact: no, measured or rounded value
Reference conditions. Test pressure 200 Pa (ISO 9237 industrial fabrics, EN filter media); assumes flow proportional to pressure difference.
Typical uses
- Industrial and filter fabrics
- Nonwoven filter media in Europe
