Two new EMC standards have been made available from the International Electrotechnical Commission (IEC). CISPR 22 Ed. 6.0 (2008-09) is entitled “Information Technology equipment – Radio disturbance characteristics – Limits and methods of measurement.” Procedures are given for the measurement of the levels of spurious signals generated by the ITE (information technology equipment), and limits are specified for the frequency range 9 kHz to 400 GHz for both Class A and Class B equipment. No measurements need to be performed at frequencies at which no limits are specified. The intention of this publication is to establish uniform requirements for the radio disturbance level for the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement, and to standardize operating conditions and interpretation of results. This sixth edition cancels and replaces the fifth edition published in 2005.Project IEC 61000-4-2 Ed. 2.0 (2008-09) deals with “Electromagnetic compatibility – Part 4-2: Testing and measurement techniques – Electrostatic discharge immunity test.” The voting period for this Final Draft International Standard is Sept. 19, 2008 to Nov. 21, 2008. Those who purchase this draft version will receive the definitive version when it becomes available. For more information, or to purchase these publications, go to the IEC website. Testing to international standards can sometimes be problematic. Remember you can always weigh in on the Interference Technology Testing Forum. Try it now!
