METHOD AND APPARATUS FOR MEASUREMENT OF THE PERMEABILITY TO WATER |
| 摘要 |
A method for measuring the permeability of pervious sheet material is disclosed; the measurement is based on the flow rate of water ejected at a given pressure between 2 and 1000 kPa through a nozzle pressed against one surface of the sheet material whose permeability is to be measured. |
