need help, RTCA/DO160 section 23. lightning, direct effect
(OP)
we have a tube shaped valve made of anodized aluminum. we got the following test requirements. i am not familiar with the lightning direct effect test. how it is done. does the requirement make sense, DO160E has only components A, B, C, D. no waveform A,B,C,D. at 400A and 40A, how to meet the coulomb numbers specified in DO160E in the time period specified ? and more questions....
thanks a lot.
the complete requirements -
The valves shall be able to conduct a 400 A Waveform B (as per RTCA/DO160, Section 23) lightning transient in a safe manner that causes no catastrophic or hazardous effect to the aircraft.
The valves shall be able to conduct a 40A Waveform C (as per RTCA/DO160, Section 23) lightning transient in a safe manner that causes no catastrophic or hazardous effect to the aircraft.

It may also make a difference as to what type of valve and what is the hazard being protected against (loss of function, inadventent actuation, fire or explosion, etc.)
