RTCA DO-160 – Section 17.0 – Voltage Spike
This test determines whether the equipment can withstand the effects of voltage spikes arriving at the equipment on its power leads, either ac or dc.
The main adverse effects to be anticipated are:
Permanent damage, component failure, insulation breakdown.
Susceptibility degradation, or changes in equipment performance.
Category A: Equipment intended primarily for installation where a high degree of protection against damage by voltage spikes is required is identified as Category A.
Category B: Equipment intended primarily for installations where a lower standard of protection against voltage spikes is acceptable is identified as Category B.
