With the increase of appliances equipped with the Internet of Things capabilities, with appliances now in a standby mode, waiting for the wireless operational commands, electronic on/off position, or utilizing an electronic protective control circuit in addition to wireless compliance testing, the need to meet safety standards for wireless and other product safety standards is crucial. When using IEC/EN 60335-1 for compliance testing, additional EMC immunity testing will be needed. These requirements were not applicable unless equipment includes electronic standby mode or safety mode for runaway conditions. Testing parameters may differ from those previously found under the EU EMC Directive, or under the Product Safety requirements found in the Radio Equipment directive.
The concern is that an unsafe condition may occur if the electronic standby mode is interfered with, causing a device to start when not intended, or creating a hazardous condition. These acceptance parameters may not have been considered when performing compliance testing under the EMC requirements found in the harmonized standard IEC/EN 55014-2 for immunity.
