From the very day a wire is manufactured, its insulation begins to age and deteriorate, a process that is accelerated by temperature extremes, harsh environments, or tiny nicks during manufacturing. Because invisible breakdowns in insulation can cause hazardous situations or equipment failures in flight, insulation resistance (IR) testing is required for all flight-worthy military and commercial aircraft electrical wiring harnesses. Navigate to https://www.interconnect-wiring.com/blog/is-insulation-resistance-testing-important/ to discover how these non-destructive high-voltage tests are performed and how they ensure ultimate aerospace safety.
