BS EN IEC 55011:2025

What is BS EN IEC 55011:2025 RF disturbance limits for ISM equipment about? 

This updated international standard gives emission requirements to protect radio services from radio frequency interference.

Who is BS EN IEC 55011:2025 RF disturbance limits for ISM equipment for? 

- manufacturers and importers of industrial, scientific and medical electrical equipment;

- electrical appliance manufacturers of household equipment falling into the industrial, scientific and medical categories;

- noise inspectors;

- regulatory bodies;

- procurement and design engineers;

- test laboratories.

What does BS EN IEC 55011:2025 RF disturbance limits for ISM equipment cover? 

BS EN IEC 55011 covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. It applies to industrial, scientific and medical ISM electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use local radio-frequency energy. 

NOTE: Robots used for industrial, scientific and medical applications are in the scope of this document, such as welding robots, spraying robots, handling robots, processing robots, assembly robots, medical robots, education and experimental robots.

Why should you use BS EN IEC 55011:2025 RF disturbance limits for ISM equipment?

• BS EN IEC 55011:2025 specifies the latest international requirements and thus enables your products to maintain performance in the presence of electromagnetic energy without interfering with other products. This helps protect the reputation of your brand.
• BS EN IEC 55011:2025 incorporates updates that reflect state of the art technologies and align with other CISPR standards. The revision recognizes the increasing use of the radio spectrum at ever higher frequencies; for the first time specifies limits for conducted disturbances on the wired network port; includes requirements for non-radio products that integrate radio devices; and includes definitions for various types of robots as well as measurement setups and operating modes.
• BS EN IEC 55011:2025 enables regulators to assess all technology, including state of the art, for consistent compliance with the latest requirements and has increased the practicality of testing to state of the art technology.
• BS EN IEC 55011:2025 helps procurement and design engineers analyse the latest technical requirements.
• BS EN IEC 55011:2025 is also referenced by all industrial EMC standards (including the generic industrial emissions standard BS EN 61000-6-4) and is widely adopted as it covers any product used as industrial equipment or when the equipment is high power unless covered by other CISPR product/product family emission standards.
  

What has changed?

BS EN IEC 55011:2025 supersedes BS EN 55011: 2016+A2: 2021. In comparison with the previous edition, the following significant technical changes have been made:

a) introduction of limits for radiated disturbances in the frequency range above 1 GHz for group 1 equipment in line with the requirements given in the generic emission standards;

b) introduction of limits for conducted disturbances on the wired network port in line with the requirements given in the generic emission standards; 

c) introduction of requirements for equipment which incorporates radio transmit/receive functions; 

d) introduction of definitions for various types of robots; 

e) consideration of some particular conditions when measuring robots, such as measurement setups and operating modes of robots.
