The International Electrotechnical Commission released a new test procedure, IEC/TS 62132-9. IEC/TS 62132-9 applies to “Integrated circuits – Measurement of electromagnetic immunity– Part 9: Measurement of radiated immunity – Surface scan method.”  The document is available for purchase on the IEC website.

EMC & eMobility

For a company embarking on EMC testing for either component or vehicle-level testing of their EV products, it is necessary first to have a good understanding of the EMC regulatory situation.

IEC TS 62132-9:2014 provides a test procedure, which defines a method for evaluating the effect of near electric, magnetic or electromagnetic field components on an integrated circuit (IC). This diagnostic procedure is intended for IC architectural analysis such as floor planning and power distribution optimization. This test procedure is applicable to testing an IC mounted on any circuit board that is accessible to the scanning probe. In some cases it is useful to scan not only the IC but also its environment. For comparison of surface scan immunity between different ICs, the standardized test board defined in IEC 62132-1 should be used. This measurement method provides a mapping of the sensitivity (immunity) to electric- or magnetic-near-field disturbance over the IC. The resolution of the test is determined by the capability of the test probe and the precision of the Probe-positioning system. This method is intended for use up to 6 GHz. Extending the upper limit of frequency is possible with existing probe technology but is beyond the scope of this specification. The tests described in this document are carried out in the frequency domain using continuous wave (CW), amplitude modulated (AM) or pulse modulated (PM) signals.”
