What is EMC certification?

EMC certification is the EMC Electromagnetic Compatibility Directive under CE certification, which is the ability to detect equipment or systems that operate compliantly in their electromagnetic environment without causing intolerable electromagnetic interference to any equipment in their environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; on the other hand, it means that the appliance has certain electromagnetic interference in the environment. degree of immunity, ie electromagnetic susceptibility.

In the International Electrotechnical Commission standard IEC, the definition of electromagnetic compatibility is: the system or equipment can work normally in the electromagnetic environment where it is located, and it will not cause interference to other systems and equipment.

EMC includes two parts: EMI (electromagnetic interference) and EMS (electromagnetic tolerance). The so-called EMI electromagnetic interference is the electromagnetic noise generated by the machine itself in the process of performing its due functions that is not conducive to other systems; and EMS refers to the machine. The ability to perform its intended function independently of the surrounding electromagnetic environment.

EMC Test Process

The applicant fills in the application form, provides product pictures and material list, and determines the directives and harmonized standards that the product conforms to;

Provide samples to determine the detailed requirements that the product should meet;

testing products and verifying their compliance;

Drafting and maintaining technical documents required by the Directive;

After the test is passed, the report is completed, the project is completed, and the CE certification report is issued. Affix the CE mark to your product and make an EC declaration of conformity.
