Re: [PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

This was pretty much done in the 90s with many round robin tests. The culprit is the lack of di/dt control and lack of control on EM radiation from the simulator. The two factors dominate everything else. No need to duplicate previous work. Just read the papers on the results from the significan

Re: [PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

No insight into what Doug mentioned, but before tightening up on equipment performance requirements, with attendant cost impact to test facilities, I would want to know that the variability between test facilities due to practice are not the dominating factor. I would want to improve test procedur

Re: [PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

All manufactured products have tolerances in their specifications even if the spec sheet doesn't state a tolerance for certain parameters (unless stated as min or max). Even if all the different manufacturers follow the same basic design requirements defined in the test standard, the resultant pro

Re: [PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

My experience, is that all brands, commercial and custom private built, will all make for different results. The ESD generators can all make the required waveforms as poorly defined and tested. Yet each different brand or model will give different results. Why ?  Incomplete performance definitio

Re: [PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

Hi Montara, There are more stories than I can type here. The standard as written is not very good. We addressed this in the early to mid-1990s and determined what was necessary. We also did a lot of round robin testing. Probably most of what you want has been published in the 1990s. Look at the

[PSES] Any Different Results in ESD Testing when Changing Brands of ESD Simulator (IEC 61000-4-2)

Hi! Does anyone have any stories that can be shared of a product getting a different ESD test result when changing the brand/model of ESD simulator? I am a member of the US Technical Advisory Group (TAG) for CISPR/I international standards committee (Electromagnetic compatibility of informat

[PSES] EN 61010-1 accessible Energy Hazard

All Is there a clause/requirement in 61010-1 similar to 60950-1 clause 2.1.1.5 where a SELV source >240 VA is not permitted to be accessible in an Operator Area The specific example I'm looking at is a pair of rack mounted units where the 10V/40A output has been paralleled with a 2nd unit in t
