Fluid Resistance Testing of Electrical Wire Used in Aircraft and Missiles. Part III.

Several types of insulated electrical wire purchased to MIL-W-22759, MIL-W-81044, and MIL-W-81381, along with a new fluoropolymer insulated wire, were immersed in solvents purchased to MIL-C-43616 and TT-R-248. The ability of the insulation to withstand degradation by the solvents was determined by subjecting the conditioned wire to a dielectric withstand voltage test. This testing differs from previous testing in that the fluids were maintained at 75 C during immersion of the wire specimens. (Author)
