Two new EMC standards are available from the International Electrotechnical Commission. CISPR 14-2 Ed. 1.2 (2008-07) is entitled “Electromagnetic compatibility – Requirements for household appliances, electric tools, and similar apparatus – Part 2: Immunity – Product family standard.” This document deals with the electromagnetic immunity of appliances and similar apparatus for household and similar purposes that use electricity, as well as electric toys and electric tools if the electric voltage of the apparatus is not more than 250 volts for a single-phase apparatus that is to be connected to phase and neutral or 450 volts for other apparatus. It specifies the immunity requirements in relation to continuous and transient and conducted and radiated electromagnetic disturbances, including electrostatic discharges. The apparatus may incorporate motors or heating elements or both. Also, it may contain electric or electronic circuitry and may be powered by the mains, by batteries, or any other electrical source. Immunity requirements in the range of 0 Hz to 400 GHz are covered. Project IEC 61000-4-6 Ed. 3.0 (2008-07) is entitled “Electromagnetic compatibility – Part 4-6: Testing and measurement techniques – Immunity to conducted disturbances induced by radio frequency fields.” This is a final draft version with a voting period of July 18, 2008 to September 19, 2008. Purchasers of this draft version will receive a final version once it is approved. To learn more, or to purchase either standard, go to the IEC website. International standards play a vital role in EMC. Check out the latest developments in standards that affect your sector of EMC by using the channels feature of the Interference Technology website.
