Millimetre per Second At 100 Pa (mm/s @100 Pa)
Air permeability in mm/s measured at 100 Pa, the ISO 9237 condition for apparel fabrics. As a permeance it is 10 µm/(Pa·s) per mm/s.
Symbol: mm/s @100 Pa
Quantity: air permeance (air flow per unit area per unit pressure difference)
SI relation: 1 mm/s @100 Pa = 10 µm/(Pa·s)
Derivation: 1 mm/s ÷ 100 Pa = 10⁻⁵ m/(Pa·s) = 10 µm/(Pa·s); the same number as L/(m²·s) at 100 Pa.
Exact: no, measured or rounded value
Reference conditions. Test pressure 100 Pa (ISO 9237 apparel fabrics); assumes flow proportional to pressure difference.
Typical uses
- Apparel and shirting fabrics (ISO 9237)
- Comparing fabric results with paper permeance
