GB/T 10340-2008 "Determination of Filtration Rate of Paper and Board" specifies the method for determining the filtration rate of paper and board. It is applicable to filter paper and board with certain wet strength but not to filter paper and board with non-hydrophilic or incompletely hydrophilic surfaces. Under a pressure difference of 1 kPa, the time for 100 mL of water to pass through a 10 cm² sample or the volume passing per unit time is measured. The standard defines sample pretreatment, instrument parameters, and testing procedures to ensure the accuracy and comparability of filtration performance testing.
