MEDIA TEST METHODS

Figures 11 and 12 show a test apparatus specifically intended

for use with solvents and Figure 13 an apparatus for aqueous

solutions. This test system has resulted in a realistic test

environment that provides electrical bias,

in situ measurements,

consistent stoichiometry, and temperature control all within a

safe environment. The safety aspects of the testing were

obtained by creating an environment free of oxygen to eliminate

the possibility of a fire. Results from the testing have included

swelling of silicone materials, corrosion, and adhesive failures.

harsh media to accelerate the failure mechanisms or demonstrate compatibility.
