Plain-English Explainer
EUROCAE ED-344 is a process specification providing test guidelines for assessing electrical-insulation material ageing in high-voltage systems.
As propulsion and power-distribution voltages increase, traditional aerospace insulation test methods may not be sufficient to assess service life under combined temperature, altitude, humidity and electrical stresses.
EUROCAE WG-116 lists ED-344 as published on 31 August 2026.
