In that test, the Volt was subjected to a simulated side-impact collision into a narrow object like a tree or pole followed by a rollover, the agency said.

The corrosion resistance of deposits and covering power of the plating bath were tested respectively by neutral salt spray test and inner-pole method, and the hardness of deposits was also measured.

This paper tries to predict the insulation ageing of power capacitor according to the pole-to-case partial discharge test.
