Introduction to EMC testing——ZRLK

What is EMC testing

EMC testing is also called electromagnetic compatibility (EMC), which refers to the comprehensive evaluation of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products. It is one of the most important indicators of product quality. The measurement of electromagnetic compatibility The test site and test equipment are composed. The purpose of EMC testing is to detect the influence of electromagnetic radiation generated by electrical products on the human body, the power grid in public places and other electrical products that work normally.

What equipment needs to do battery compatibility instructions

According to the directive Article 2.1, the applicable objects of the EMC directive include all devices that are prone to electromagnetic interference, or devices whose functions are susceptible to electromagnetic interference.

EMC electromagnetic compatibility fees and directives

CE certification for certain types of products is only required to pass the CE-EMC directive. However, if the working voltage of the product is AC (50~1000V), DC (75V~1500V), the safety CE-LVD certification is required. The cost between the two is different. The cost of CE certification for mechanical products is much higher than that of ordinary products, which involves factory audit procedures and evaluation.

Electromagnetic compatibility (EMC) is a comprehensive assessment of the electromagnetic field interference (EMI) and anti-interference ability (EMS) of electronic products. It is one of the most important indicators of product quality. The measurement of electromagnetic compatibility consists of test sites and test instruments. Because of the conventional test items of EMC and LVD, there are many products, engineers will carry out corresponding project tests and quotations according to the actual situation and needs of your products.
