IEC 1000 IEC 1000-4-2 ESD TESTING REQUIREMENTS All equipment destined for Europe must be able to withstand 10 strikes of ESD waveforms with Tr discharge mode (preferred) at pre-selected points accessible during normal usage or maintenance. Testing shall be performed at one or more of four (4) severity levels, depending upon equipment category. [pic] 1000-4-2 Test Conditions 1Preferred mode of testing due to repeatability. WAVEFORM PARAMETERS [pic] Upon completion of the test, the system must not experience upset (data or processing errors) or permanent damage. The waveforms are to be injected at or along the DUT’s body which is accessible in normal set-up and operation. ……
