Each product is tested for its absorbency speed. A specific amount of saline solution is dosed into the centre of the sanitary pad using the dosage pump. The amount of time it takes for the liquid to disappear is recorded and the process is repeated once more after waiting for three minutes. The total time for both gushes to absorb is taken as the absorption speed.

We test the wet feeling (or rewet) five minutes after the last gush from the absorbency test. We place six pre-weighed dry filter papers on the sanitary pad and hold them down for 30 seconds. The filter paper is then removed and immediately weighed. Ideally, the filter paper should remain relatively dry.

We measure the force required to pull the pad from a cotton surface.

The cost per pad is the price we paid divided by the pack size tested.
