1, Measurements taken with membrane conditioned to 23°C,50%RH.

2, Conductivity measurements at 23°C,100%RH.

3, A base titration procedure measures the equivalents of sulfonic acid in the polymer,  and  uses the measurement to calculate the acid capacity or equivalent weight of the pure polymer.

4, Water content of membrane conditioned to 23°C and 50% RH(dry weight basis).

5, Water uptake from dry membrane to conditioned in water at 100°C for 1 hour (dry weight basis).
