EMC Test Lab Florida

We understand that you are looking for an EMC (Electro Magnetic Compatibility) testing laboratory in Florida. However, we still want to help you understand us; because compared to local Florida laboratories, we can save you 30% on testing and certification costs.

1. Overview of EMC Electromagnetic Compatibility

Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate in accordance with requirements in its electromagnetic environment and not to generate intolerable electromagnetic interference to any device in its environment. Therefore, EMC testing includes two requirements: on the one hand, the electromagnetic interference generated by the device to the environment during normal operation cannot exceed a certain limit; on the other hand, it means that the device has a certain degree of immunity to the electromagnetic interference in the environment, that is, electromagnetic sensitivity.

The International Electrotechnical Commission standard IEC defines electromagnetic compatibility as: a system or device can work normally in the electromagnetic environment in which it is located, and will not interfere with other systems and devices. EMC testing includes two parts: EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference is the electromagnetic noise that is not conducive to other systems generated by the machine itself in the process of performing its due functions; and EMS refers to the ability of the machine to be unaffected by the surrounding electromagnetic environment in the process of performing its due functions.

 3.EMC electromagnetic compatibility test items

(1) Equipment means any electrical, electronic or electromechanical device that works as a single unit and performs a single function.

(2) System refers to “a combination of equipment, subsystems, dedicated personnel and technologies that can perform or ensure work tasks”.

(3) Electromagnetic environment: The sum of all electromagnetic phenomena existing in a given place.

"Given place" refers to "space", and "all electromagnetic phenomena" include all "time" and all "spectrum".

4. EMC electromagnetic compatibility application areas

1) IT information technology field;
2) Modern medical equipment, medical instrument related electronic and electrical fields;
3) Automotive electronics, the application of automotive electronic technology is related to the automotive electromagnetic environment, mainly caused by the electromagnetic environment of the vehicle, and the vehicle's own ability to resist electromagnetic disturbance is also crucial.
4) Mechanical equipment and electrical equipment system, EMC electromagnetic compatibility related safety requirements;
5) Due to the development of electronic, electrical, wireless communication, radar detection and other technologies and their increasing application in the aerospace field, related electromagnetic compatibility (EMC) and electromagnetic interference (EMI) issues are also increasingly valued, and the electromagnetic compatibility discipline has therefore developed.
6) Specific safety requirements for electromagnetic compatibility EMI of lighting products;
7) Household appliances, due to the continuous deterioration of the electromagnetic environment, electromagnetic compatibility issues have also received more and more attention, and the electromagnetic compatibility standards of household appliances have also been continuously updated with actual needs.
