◮  Measurements taken with membrane conditioned to 23° ℃,50% RH.
◮  Conductivity measurements at 23 ℃,100% RH.
◮  A base titration procedure measures the equivalents of sulfonic acid group in the resin, and uses the measurement to calculate the acid capacity or equivalent weight of the membrane.
◮  Water content of membrane conditioned to 23*C and 50%RH(dry weight basis).
◮  Water uptake from dry membrane to conditioned in water at 100C for l hour(dry weight basis)
