EMC
EMC (Electro Magnetic Compatibility) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its environment.
More Introduction
1. Introduction to EMC Certification
EMC (Electro Magnetic Compatibility) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any device in its 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; degree of immunity, ie electromagnetic susceptibility. EMC certification is a directive on electromagnetic compatibility in CE certification.

3. EMC certification process
Step 1: Application (1. Fill in the application form; 2. Provide information and send samples);
Step 2: Quote (according to the information you provide, an engineer will formulate the corresponding standard, test time and corresponding cost);
Step 3: Payment (After the applicant confirms the quotation, signs the application form and service agreement and pays the payment);
Step 4: Testing (the laboratory will conduct a full set of tests on the applied product according to the relevant EU testing standards);
Step 5: The test is passed and the report is completed;
Step 6: The project is completed and CE certificate is issued.

5. CE-EMC certification validity period
In the case that the product design, regulations and instructions have not changed, the CE-EMC certification report can always be valid, unless the buyer has special requirements.
