Overview
IEC TR 63216:2019 provides guidance for the electromagnetic compatibility (EMC) assessment of low-voltage switchgear, controlgear and their assemblies - especially those with built-in electronic circuits and incorporated radiocommunication functions. The technical report defines homogeneous categories of electromagnetic environments to harmonize product and assembly EMC requirements, with the goal of ensuring safe, reliable operation and effective radiocommunication performance in intended environments such as electrical distribution in infrastructure, commercial and industrial buildings, and machinery control (including motor-driven systems).
Key topics and technical content
- Classification of electromagnetic environments - tailored environment categories derived from the IEC 61000 family and aligned with zones like those in IEC 61131-2.
- EMC assessment principles - system-level approach to determine compatibility between equipment and its expected electromagnetic environment.
- Ports of entry and coupling mechanisms - identification of how disturbances enter equipment (power, signal, enclosure, antennas).
- Emission and immunity considerations - guidance on radiated and conducted emissions, immunity phenomena (including radiated immunity, common-mode RF, voltage dips, transients and overvoltages).
- Radiocommunication functions - treatment of incorporated wireless/radio communication within switchgear and controlgear assemblies.
- Drafting EMC requirements - recommendations for writing product and assembly standards, including what environmental information and test evidence to specify.
- Information for users and installers - instructions for use, good wiring practices, and information related to emission limits and safe installation.
- Informative annexes - rationale based on network topology and a catalogue of EMC phenomena to support test selection and interpretation.
Practical applications and who uses this standard
IEC TR 63216:2019 is useful for:
- Manufacturers and product designers of low-voltage switchgear and controlgear who need to define or verify EMC performance.
- Standards committees and test laboratories drafting or applying product/assembly EMC requirements and test programs.
- EMC engineers and system integrators assessing compatibility in building distribution systems, industrial automation and machinery control panels.
- Specifiers and procurement teams seeking harmonized EMC criteria for equipment selection and acceptance.
Typical applications include defining emission/immunity test scopes, integrating radiocommunication features in controlgear, preparing installation guidance (wiring/layout), and ensuring compliance of assemblies used in industrial, commercial and infrastructure electrical distribution.
