EN55014-2:1997 + A2:2008 is an international standard that sets the requirements for electromagnetic compatibility (EMC) of appliances, electric tools, and similar equipment. It specifies the limits of disturbance voltages or currents that these devices can produce, as well as the levels at which they must tolerate the disturbances caused by other electrical equipment.
The Purpose of EN55014-2:1997 + A2:2008
The main purpose of this standard is to ensure that electrical equipment does not interfere with each other's operation or cause harm to users. It aims to regulate the electromagnetic emissions and susceptibility of equipment to achieve a reasonable level of electromagnetic compatibility in all environments.
Requirements and Test Methods
EN55014-2:1997 + A2:2008 specifies different requirements for emissions and immunity, depending on the type and intended use of the equipment. The standard defines limits for conducted and radiated disturbances, harmonics, voltage fluctuations, and flicker, among others. It also provides test methods to assess the compliance of equipment with these specified limits.
For emissions testing, the standard defines several measurement methods such as direct voltage measurement, current measurement, and antenna measurements. These tests evaluate the ability of the equipment to limit the electromagnetic noise it generates.
On the other hand, immunity testing assesses the equipment's ability to function properly when subjected to various disturbances generated by other devices. This includes electrostatic discharge, fast transients, and surges, among others. The standard prescribes specific test procedures and defines the performance criteria that equipment should meet to qualify for compliance.
Compliance and Importance
Compliance with EN55014-2:1997 + A2:2008 is essential for manufacturers and importers of electrical equipment. By ensuring their products meet the requirements of the standard, they can demonstrate that their devices are safe to use and do not cause interference or harm to other electrical systems.
Furthermore, compliance with this standard allows the smooth operation of various electrical devices in different environments without significant electromagnetic disturbances. It helps prevent potential malfunctions or interferences that could affect the functionality of essential systems, such as medical equipment, communication networks, and industrial processes.
In conclusion, EN55014-2:1997 + A2:2008 plays a crucial role in establishing electromagnetic compatibility for electrical equipment. By defining strict limits and test methods, it ensures that devices meet the necessary requirements to prevent harmful interference, promoting a safer and more reliable electrical environment.
