Diaper leakage tester standards

　　The three elements of permeability: slip infiltration, backflow, and leakage.

　　Slippery infiltration: refers to the volume of test solution that is not absorbed when passing through the surface of an inclined specimen.

　　Infiltration amount: The quality of the test solution that is absorbed by the sample and returned to the surface layer under a certain pressure.

　　Leakage amount: The quality of the test solution that passes through the anti leakage bottom film under a certain pressure after the sample absorbs a certain amount of test solution.

　　Applicable standards:

　　GB/T 28004-2011 Diapers (Sheet/Pad)

　　GB/T 8939-2008 Sanitary napkins (including sanitary pads)

　　QB/T 2493-2000 diapers (piece/pad)

　　After absorbing a certain amount of test solution, the sample of the diaper leakage tester passes through the quality of the test solution through the anti leakage bottom film under a certain pressure.

　　Technical indicators:

　　1. Test slope angle: adjustable at 10 ° and 30 °

　　(Diapers 30 ° ± 2 °, sanitary napkins 10 ° ± 1 °)

　　2. Discharge funnel: 150mL

　　3. Standard pressure block with a diameter of 100mm: 1.2kg

　　Configuration list:

　　1 tester

　　2. One beaker (500ml)

　　3. One measuring cylinder (10ml, 100ml) each

　　4. Four stainless steel clips

　　5. One standard pressure block weighing 1.2kg
