Nonwoven Liquid Penetration Tester STD-MB03A

Principe d'essai

A solution of known volume (e.g., artificial urine with a surface tension of 70dyn/cm) is placed in a teflon-lined container.A solenoid valve is used to drain the liquid at a constant rate through the center hole of the nonwoven upper plate (through the electrode plate).The two electrodes start the timer with a conductive liquid.The nonwoven sample is placed on a set of 5/10 pieces of filter paper that ACTS as a suction liquid.When all the conductive liquid enters the suction layer, the circuit current will interrupt and stop the timer.EDANA requires the configuration of artificial urine at a rate of 25ml/3.5±0.25s.
