Commonly used immunity test standards [Copy link]

Abstract: This paper introduces the purpose, method, severity level and requirements of several immunity tests in detail. The electromagnetic compatibility certification work in my country has been launched, and the first batch of product categories and contents for implementing electromagnetic compatibility have been basically determined. They are sound and television broadcast receivers and related equipment, information technology equipment, household and similar electric and electric heating appliances, electric tools and similar electrical appliances, power supplies, lighting appliances, vehicles, motor boats and spark ignition engine drives, financial and trade settlement electronic equipment, security electronic products, sound and television signal cable distribution system equipment and components, low-voltage electrical appliances. Although the products are different and the product family test standards cited are different, the immunity test contents are basically the same, which are electrostatic discharge, radio frequency radiation electromagnetic field, pulse group, surge, radio frequency field-induced conducted interference and voltage drop. In order to help readers understand these standards, the author tries to start from the test purpose, instrument characteristic requirements, basic configuration, standard test methods and comments on the standards, and introduce these tests in a relatively concise text to deepen the understanding of the standards.
