Electromagnetic compatibility testing in EMC lab EN 55012, CISPR 12
EN 55014 – 2:2015 Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity — Product family standard
Equivalent: CISPR 14 – 2:2015 Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity — Product family standard
Replace: EN 55014 – 2:1997 +A1 +A2 +AC Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity — Product family standard
New in this edition:
- ESD test requirements have been changed for contacts of plugs and sockets. Additionally, requirements for horizontal coupling plane and vertical coupling plane have been changed;
- Requirements are changed for large floor standing equipment in RF conducted susceptibility tests. EUT setup differs from requirements defined in IEC 61000 – 4-6:2013;
- Alternative RF radiated susceptibility testing method have been introduced– IEC 61000−4−22;
- No requirement to apply pulses line-ground for EUT without ground connection in surge tests;
Scope
Appliances and similar apparatus for household and similar purposes with rated voltage up to 250V for single phase equipment and up to 480V for other equipment (including battery powered devices).
Equipment may include motors, heating elements, electronic circuits powered by batteries, mains power, transformers or different electrical power source.
The following equipment is included in the scope of EN 55014 – 2:2015 is:
- microwave ovens for domestic use and catering;
- cooking hobs and cooking ovens, if RF energy is used for cooking;
- induction cooking appliances;
- devices for personal care equipped with UV, IR and visible light radiators;
- power supplies and battery chargers provided with or intended for devices within the scope of this standard.
Devices not intended for household use, but which may require similar immunity requirements– shops, light industry, barns, farms, if these devices are in scope of EN 55014 – 1:2006.
The following equipment is not included in scope of EN 55014 – 2:2015 is:
- Lightning equipment;
- Industrial equipment;
- Cables, switches, circuit barkers;
- Medical equipment;
- Multimedia equipment except toys;
- Radio transmitters;
- Automotive equipment;
- Infant monitoring systems.
Classification
Category 1– devices that contain no electronic circuits (motor with switch, heating elements with switch, tools with motors and switches without electronic circuits).
Category 2– devices with electronic circuits with no clock higher than 15MHz (toys, tools with electronic control, UV and IR radiators, microwave ovens).
Category 3– devices that during normal use are not connected to mains network and have no cables (battery powered devices, solar power powered devices). If equipment is charged by connecting it to mains network, it should be tested also as Category 2 equipment in charging mode.
Category 4– Devices that are in scope of 55014 – 2:2015, but not classified as Category 1– Category 3 equipment.
Requirements
Performance criterion A
The apparatus shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.
Performance criterion B
The apparatus shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the equipment is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is however allowed. No change of actual operating state or stored data is allowed. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, either of these may be derived from the product description and documentation and what the user may reasonably expect from the equipment if used as intended.
Performance criterion C
Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the controls.
