I very much doubt that you did. EN 61000-3-1 is a nullity. Theoretically, it's an overview of low-frequency conducted disturbances, but it has never been published and is most unlikely to ever be published. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Applicable EMC tests
Consider an outdoor housing intended to contain an electronic product subject to the generic EMC standards. The only electrical circuit in the housing is a heater with a PTC temperature control. The power input port is 24V AC/DC. My thinking is that this device is also subject to the generic EMC standards. EN61000-6-3 indicates that a test is not required for the enclosure since there are no high frequency sources, and the AC mains test is not required since this is a low voltage device. It would seem that the conducted emissions test on the AC/DC port is not required by a simple inspection of the electrical circuits - i.e., there are no components that will generate emissions in the frequency bands specified by CISPR22. Therefore, is it acceptable to note all of this in the test report and declare compliance to EN61000-6-3 without testing?
