If you are just looking to just tick an 'ESD Pass' box and humidity helps (and it usually does), elevate the humidity in the test area to near 60%. I have used a portable single gas burner and kettle to do this in the past. Unless the equipment is intended particular environmental conditions, it is a mandatory condition of 61000-4-3 that the climatic conditions for the test be conducted at between 30% and 60% R.H.

John. I think I answered this globally so I'll just do it locally for the moment. My humidity was a little on the low side, about 28% and theirs was closer to 38% or so. I would anticipate that might results would be the most harsh, but I am watching that as well. I was working in a Japanese factory on a design many years ago. The factors have no air conditioning of any type, and in the summer they have the windows open. I could absolutely tell when a storm unleashed rain, the humidity shot up and my ESD results got better. - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
