Gaming machines in Australia are tested to 25kV air discharge and 10kV contact discharge. Gaming regulators are more concerned about intentional interference rather that accidental. I use 61000-4-2 as the basis for my test procedure even though the gaming machine requirements do not specify. Since all software lockups are required to be manually reset by an authorised person, we pretty much test for total immunity i.e., Criteria A. About the only thing that I let through is screen flicker and short duration drop outs in communications.
In the US some regulators actually use a high frequency generator, used for testing the integrity of vacuum tubes, in lieu of a proper ESD simulator. These are uncalibrated devices and can be anywhere from 40 to 60kV. Therefore, after I have finished my precompliance testing with this device, it is a matter of crossing my fingers and hope for the best!! Cameron O'Phee. EMC & Safety Precompliance.

I have the following questions. o What types of products o What type of user environment o What is the rational for testing above 15 kV o What test equipment is used above 15 kV o What test procedure is used above 15kV o What is the pass/fail criteria above 15 kV Thanks, Richard Woods ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
