*The changes noted are the ones we feel relevant to us and our customers.
Guidance for selecting test points is given, also troubleshooting techniques in the event of inconsistent EUT response during testing. Test setup remains the same except for wearable devices, wall mounted equipment and floor standing machinery (rather just clarifying the latter equipment).
For us, most importantly, current waveform requirements, so far, we have found only one model can no longer pass calibration but believe the manufacturer is offering a free modification to bring the waveform, specifically the second peak, into the time zone allotted.
Next, doing calibrations, the setup requires modifications at the least. A full new setup if you were cutting corners to begin with (Ex. we offer the PRP for a quick verification, comparison data coming soon). We will be offering a retrofit to the VGP, extending it to and fabricated for easy install on the RGP.
DID YOU KNOW?
Most current and popular ESD generators on the market today were launched in the early 90's, after the release of the first edition of IEC 61000-4-2, establishing criteria for a current waveform for reproducability and reliable testing?
Air discharge requirement is pretty obscure, for very old and home brew ESD guns. Last part on ESD generator calibration, is the measurement uncertainty, thank god I have Robert for that….
The best part of the standard I can’t share, because all our competitors will start ripping me off. They’ll have to take the time to read and figure it out themselves.
All in all this is a well done revision, there was a lot of thought put into amongst the technical committee. It is really dialing in the details, pushing manufacturers to build better quality ED guns as well as users to perform mindful, but efficient testing. It is moving us toward a much more consistent industry. If you have any specific questions please contact us directly for our two cents.
