You would need to provide the specific method/procedure number. There can be more than one humidity test. For some stuff there can be significant latitude in test method, depending on the LCEP.

Stymied over a simple question. I'm going to do a MIL-810 humidity test for 10 days. But reading the details of the pertinent section I can't really determine if the product is supposed to operational the whole time or just brought up during the required 5th and 10th cycle functional tests. My presumption is that it would be off during the rest of time (they do discuss long term storage in humid areas) so that the humidity the self-heating of the product while on doesn't ameliorate any of the negative of the effects of humidity fungal growth, deposits from external sources, hygroscopic issues et al. They spend time discussing tailoring the test but this really isn't a tailorable consideration. It either is or it is not. So the devil is in the details and I think they left one out. I can't afford the time or cost of running this twice and my direct customer doesn't know either - and getting answer from his customer is egregious Anybody?
