The GB/T 10340-2008 standard specifies a method for determining the filtration rate of paper and Cardboard, which is suitable for filtrated paper and Cardboard with a certain wet strength. The standard evaluates the filtration performance by measuring the time it takes for water to pass through the sample at a constant pressure difference of 1 kPa. This standard does not apply to paper that has been Resin treated or has a non-hydrophilic surface. Standardized test methods enable accurate evaluation of the filtration efficiency of paper, guiding the application and quality control of the filtrated material.
