Aircraft Hypot Test

I am interested to know if there is a specification for dielectric withstand test for aircraft. I can't find anything concrete in DO-160. I know of Mil-std-202, and expect I can apply it to civilian aircraft. I have a client that insists he does not have to hipot and I disagree. My gut tells me that any gear that is isolated from ground should be tested in some manner. I think good engineering practice would dictate a test. The unit runs off of 120vac wild power. That is I think 360Hz - 800Hz. Don't quote me but on that but it is close. We have caps to ground so would go with the DC hypot. My guess would be (2x120+1000)*2^0.5 Make sense? regards, Bob

Antonio is correct. Regardless of what the top level requirements say you have to develop to a standard, just like you have to in med tech. BTDT, for more than three decades now. If a design doesn't pass that agency test it is not a useful design.

All this is spelled out in great detail in RTCA/DO-160 which all designers of aircraft electronics must follow.
