On October 13, according to CCTV News, the International Electrotechnical Commission (IEC) officially published the international standard in the field of electrical relays titled "Electrical Relays - Testing and Measurement - Part 3: Coil Characteristics of Electrical Relays." This standard was developed with Chinese experts serving as the project leaders, in collaboration with experts from multiple countries including Germany, Austria, Italy, Switzerland, and Japan. It provides advanced and unified testing method standards for the international trade of electrical relay products.
Electrical relays are core basic components in fields such as industrial control, power systems, home appliances, automotive, and communications. Basic electromechanical relays are the most widely used type of electrical relay. The coil plays the role of the "core driving source" and "energy conversion hub" in basic electromechanical relays, serving as the key component for relays to achieve "controlling large with small" and "controlling machinery with electricity." Coil characteristics include multiple parameters such as coil resistance, coil impedance, coil inductance, coil power consumption, and coil transient suppression. These are important characteristics and core parameters for evaluating basic electromechanical relays, directly determining the performance and reliability of electrical relays.
The publication of this standard clearly unifies the testing conditions and procedures for electrical relay coil parameters, resolving the issues of insufficient detail and weak operability in existing industry standards. It provides reproducible and comparable technical references for global electrical relay manufacturers, users, and testing institutions.
This standard will serve as an important basis for performance evaluation by global manufacturers, users, and third-party testing institutions, holding significant value for industrial standardization, product quality, and international trade.
