Water resistance Pursuant to JIS L 1092 Test Method for Water Resistance of Textiles(Hydrostatic Pressure Test), Method B(High Water Pressure) *Using mesh cover
Air permeability Pursuant to JIS L 1096, Method B(Gurley Test Method)(equivalent to JIS P 8117, Method B)

This was measured by the method specially developed by Seiren for the measurement of the parameter with an sample opening of 1.2mm×2.0mm. (The measurement was made under an open system where the film underwent increased sound permeation loss in the low frequency range due to sound diffusion.)
