PC Products EMC Certification Testing

EMC (Electromagnetic Compatibility) is an important indicator for evaluating product quality. It refers to the ability of a product to limit electromagnetic interference (EMI) and its resistance to electromagnetic interference (EMS), which are key components of overall product quality.

This definition includes two aspects. On the one hand, it requires that electronic equipment does not exceed a certain level of electromagnetic interference in normal operating conditions, i.e., EMI. On the other hand, it requires that electronic equipment possesses a certain level of immunity to electromagnetic interference from the environment, i.e., EMS. The purpose of emc testing is to evaluate the impact of a product’s electromagnetic emissions on human health, public power grids, and other electronic products that operate normally.
