2. Coverstock Wetback Principle

Place the covering material on a standard absorbent pad, and perform 3 liquid strike through tests with the specified simulated baby weight(SBW). After the third penetration, place the simulated baby weight on the covering material and absorbent pad to spread the liquid evenly.

A known mass of absorbent paper is placed on the tested covering material, and the simulated baby weight is re-placed on the absorbent paper. The mass of liquid absorbed by the absorbent paper is defined as the amount of rewetting.
