WATERPROOFING
WATER COLUMN TEST (known as the “Schmerber” test)
The strength of a fabric is measured in water pressure, expressed in mm water column (test based on the JIS 1092B standard). The greater the pressure, the more the fabric is waterproof.
With waterproofing of 20,000 mm, our jacket 500 boasts a high level of waterproofing
A component with waterproofing of 20,000 mm can withstand a pressure of 2.0 bar.
