What is IEC 61000-4-9:2019?

IEC 61000-4-9:2019 is an international standard that deals with the immunity of electrical and electronic equipment to conducted disturbances induced by electromagnetic fields coming from power and traction systems. It specifies test voltage levels, test equipment, test setup, test procedures, and requirements for measuring and documenting the immunity performance of equipment under defined electromagnetic field conditions.

Scope of IEC 61000-4-9:2019

This standard applies to electrical and electronic equipment intended for use in residential, commercial, and industrial environments. It addresses both continuous and transient phenomena, including long-duration variations and short-duration voltage interruptions. The purpose of this standard is to establish a common reference for evaluating the immunity of equipment to conducted disturbances originating from high-voltage and low-voltage power and traction systems.

Key Requirements of IEC 61000-4-9:2019

IEC 61000-4-9:2019 sets forth various key requirements that electrical and electronic equipment must meet to demonstrate adequate immunity against conducted disturbances. These include immunity level classification, test voltage levels, test frequencies, test signal characteristics, and test configurations. The standard also specifies different test procedures for equipment operating at mains voltages and at input/output ports which are not directly connected to power or signal lines.

Benefits of Complying with IEC 61000-4-9:2019

Complying with IEC 61000-4-9:2019 brings several benefits to manufacturers, suppliers, and end-users of electrical and electronic equipment. Firstly, it ensures that equipment can operate properly without being affected by conducted disturbances induced by electromagnetic fields from power and traction systems. This contributes to the overall reliability and safety of the equipment. Additionally, complying with the standard allows manufacturers to demonstrate the quality and performance of their products, which can enhance customer trust and satisfaction. Lastly, compliance with IEC 61000-4-9:2019 enables seamless interoperability between different types of equipment in various environments, leading to better integration and compatibility.
