QUALITY & STANDARDS severe testing is not necessary. For example, an electronic controller that has a membrane switch that sends a signal to other circuitry to put the unit into a stand-by mode would require testing. In order to determine applicability, the basic main question that should be asked is whether there are electronic circuits in an appliance that can be susceptible to external electromagnetic interference that could result in a hazardous condition. If so, then the appliance should be subjected to testing at these higher severity levels. All appliance modes should also be evaluated. As a result of this testing, the appliance should not undergo any dangerous malfunction, the protective electronic circuits should not fail, and appliances with an applicable off switch or stand-by mode should not become operational. Since there is no grandfather provision, manufacturers of household and similar appliances should immediately have their products evaluated, and potentially tested. This will assure that manufacturers of such products are prepared for the latest EN 60335-1 EMC test requirements. 95% @ 10 ms ~~~ 20% @ 5s 30% @ 500 ms 60% @ 200 ms > 95% @ 10 ms > 95% @ 20 ms For more information, enter . . . . . . . . . . . . . . . . . . . 311 Or email: mhaynes@dlsemc.com or sgrimes@dlsemc.com N/A Applicable -13 Harmonics Class II Interharmonics Table 1.
