IEC 63044-5-3:2017

Overview

IEC 63044-5-3:2017 is an international standard published by the International Electrotechnical Commission (IEC) that defines electromagnetic compatibility (EMC) requirements for Home and Building Electronic Systems (HBES) and Building Automation and Control Systems (BACS) used specifically in industrial environments. This standard complements other IEC product EMC standards and applies to devices within an HBES/BACS network where no dedicated EMC standard exists. The scope includes devices such as operator stations, control devices, field devices, cabling, and other interfaces used in industrial environments per IEC 61000-6-2 definitions, including office spaces within industrial premises.

The standard ensures that HBES/BACS devices maintain minimum EMC performance levels to operate reliably in potentially harsh electromagnetic conditions typically encountered in industrial settings, without interfering with other equipment. IEC 63044-5-3:2017 is designed to be read alongside IEC 63044-5-1:2017, which outlines broader EMC requirements, conditions, and test set-ups for HBES/BACS.

Key Topics

• Scope and Application
  Applies to HBES/BACS devices and network interfaces installed in industrial environments, excluding industrial automation systems but including office spaces within industrial premises.

• EMC Immunity Requirements
  Immunity testing follows the generic industrial environment standard IEC 61000-6-2, covering enclosure, power inputs, I/O signal ports, and network ports. Key immunity phenomena addressed include:

  • Radio-frequency common mode disturbances (0.15 to 80 MHz)
  • Electrical fast transients (burst)
  • Surge immunity (line to earth and line to line)

  These requirements ensure devices can withstand electromagnetic disturbances typical in industrial environments without performance degradation.

• EMC Emission Requirements
  Emission limits are based on IEC 61000-6-4:2018, the generic emission standard for industrial environments, ensuring HBES/BACS devices do not emit disruptive electromagnetic interference that could affect other equipment.

• Test Conditions and Performance Criteria
  Standard test setups and performance criteria align with IEC 63044-5-1:2017 to provide consistency across the HBES/BACS range of devices.

Applications

IEC 63044-5-3:2017 is critical for manufacturers, integrators, and operators of home and building automation equipment intended for use in industrial settings with demanding EMC requirements. Typical applications include:

• Industrial Office Spaces
  Automation and control equipment installed within office areas of industrial plants needing robust EMC performance.

• Building Management Systems in Industrial Facilities
  Devices managing lighting, HVAC, security, and human-machine interfaces that must operate reliably alongside heavy industrial machinery.

• Operator Stations and Control Devices
  Interfaces that require immunity to common industrial electromagnetic disturbances to maintain safe and effective control.

• Field Devices and Network Interfaces
  Sensors, actuators, and communication devices connected to HBES/BACS networks, especially those with long cable runs susceptible to interference.

This standard helps ensure that building automation systems sustain functionality and comply with regulatory EMC requirements, reducing operational disruptions and maintenance costs.
