Fluid Immersion Testing of EWIS Components
From fuel to hydraulic oil to sodas, aircraft wires and cables are exposed to a wide range of fluids and, generally, the insulations must not show degradation that would impact their airworthiness. Material compatibility is important for all parts of the aircraft and the wiring system is no exception. The means to assess material compatibility between fluids and wires/cables is done with fluid immersion testing.
Fluid immersion testing is straightforward but requires a lot of materials, a lot of prep work, and a lot of hands-on attention to detail. The fundamental idea of fluid immersion testing is for components to be submerged in the fluid and observed for any changes to the material or components. Some test details and the impacts of the test results are covered here.

Pull Through Testing- An Addition to NEMA 27500
An area that has been poorly defined until recently has been the potential damage to wire/cable insulation due to wiring installation on aircraft. The latest revision of NEMA 27500 has looked to address this gap in cable assessments. In this article, we review the test requirement, expected performance, and what the results may mean to designers and installers.
