I had an incident where my leakage exceeded the capacity of my pad and I had some leakage onto my trousers, though my plastic pants mostly contained it. I couldn’t get to a toilet due to being stuck in a huge queue at a train station and it was very uncomfortable and stressful. Should I move up to a more absorbent pad or just treat it as a one off and see how I go? I use shaped pads with an 800ml capacity and they’re usually fine.
The quoted pad capacities are an artificial construct. There is a standard testing method which involves totally immersing the pad in water for a time designed to completely saturate it, then allowing it to drain until no more water drips out, and measuring how much water it has taken up (by weighing it). No one is going to use a pad up to this capacity, saturated over its whole area and just on the point of leaking. The figures are useful to compare the absorption levels between different pads, but they are useless to gauge how much a particular pad can safely take up. That figure is commonly 1/3 the quoted figure.
