Testing that Reaches the World
EN 61000-6-4 (Emissions)
EN 61000-6-4 establishes electromagnetic emissions requirements for electrical and electronic equipment intended for use in industrial environments. The standard is used to evaluate electromagnetic disturbances generated by equipment and help demonstrate that emissions remain within applicable limits.
Clark Testing provides EN 61000-6-4 EMC emissions testing for manufacturers and engineering organizations supporting product qualification, compliance, and design validation programs.
EN 61000-6-4 EMC Testing
Electrical and electronic equipment can generate electromagnetic disturbances through power connections, cables, enclosures, switching devices, digital circuitry, motors, power electronics, and other components.
EN 61000-6-4 provides emissions requirements for equipment intended to operate in industrial locations where a product-specific or product-family emissions standard may not otherwise apply.
Testing may include evaluation of:
- Radiated emissions
- Conducted emissions
- Emissions from AC or DC power ports
- Emissions from wired network or communication ports
- Equipment operating modes
- Frequency-dependent emission limits
- Product configuration and peripheral equipment
The specific measurements and limits depend on the equipment, ports being evaluated, operating configuration, and applicable requirements.
Radiated Emissions Testing
Radiated emissions testing measures electromagnetic energy emitted from equipment into the surrounding environment.
During testing, equipment is operated in representative configurations and operating modes while emissions are measured across the applicable frequency range.
Testing can help identify emissions associated with:
- Digital electronics
- Switching power supplies
- Motors and drives
- Internal clocks and processors
- Cables and wiring
- Power electronics
- Communication interfaces
Identifying excessive emissions during development can also help engineering teams locate potential EMC design issues before final qualification.
Conducted Emissions Testing
Conducted emissions are electromagnetic disturbances that travel through power, signal, or communication connections rather than radiating directly through the air.
EN 61000-6-4 testing may include measurements at applicable equipment ports to determine whether conducted disturbances remain within required limits.
Clark can work with customers to establish the appropriate equipment configuration, operating modes, connections, monitoring requirements, and measurement setup for the applicable qualification program.
Industrial EMC Qualification
Industrial environments often contain substantial electrical and electronic infrastructure, including motors, drives, switching equipment, automation systems, power distribution equipment, and industrial control systems.
EMC qualification helps demonstrate that equipment does not produce excessive electromagnetic disturbances within these environments.
EN 61000-6-4 addresses emissions, while other standards within the IEC/EN 61000 family address equipment immunity to electromagnetic disturbances.
Clark Testing supports broader EMC/EMI programs that may include:
- Conducted emissions
- Radiated emissions
- Radiated RF immunity
- Conducted RF immunity
- Electrostatic discharge
- Electrical fast transient/burst immunity
- Surge immunity
- Magnetic field immunity
- Voltage dips and interruptions
EN 61000-6-4 Testing at Clark Testing
Clark Testing works with manufacturers, suppliers, and engineering organizations to evaluate electrical and electronic equipment against applicable EMC requirements.
Our team can review the equipment configuration, applicable EN 61000-6-4 requirements, equipment ports, operating modes, measurement requirements, and acceptance criteria to develop an appropriate emissions test program.
