You guys are absolutely fantastic!!! I did some quick searches, while reading responses, and at this moment in time can safely reply to my designer that MIL-STD-1686, is still the document, however, I will also tell him "don't take too long to design because 1686 could be history very soon". I also informed him of EIA-625, the mention in J-Std-001, and ANSI/ESD S20.20-1999. I also marked a couple web sites for further reference. Thank You All Once Again!
