BS IEC 61000-4-36:2020

What is BS IEC 61000‑4‑36 about?  

BS IEC 61000 is a series on electromagnetic compatibility (EMC). In order to function effectively, electronic systems need to be immune to interference from other frequencies. Sometimes there is intentional interference of electromagnetic signals with malicious intent. These risks need to be mitigated. BS IEC 61000‑4‑36 addresses this challenge.  

IEMI works by introducing noise or signals into electric and electronic systems, thus disrupting, confusing or damaging these systems for malicious purposes. BS IEC 61000‑4‑36 provides test methods to determine the immunity of your equipment and systems to intentional electromagnetic interference (IEMI) sources. It introduces the general IEMI problem, IEMI source parameters, derivation of test limits and summarises practical test methods. 

Who is BS IEC 61000‑4‑36 for? 

BS IEC 61000‑4‑36 on IEMI immunity test methods is useful for: 

• Telecommunication components manufacturers 
• Design engineers / electrical engineers 
• Research and development facilities 

Why should you use BS IEC 61000‑4‑36?  

Electromagnetic compatibility means that a device is compatible with its electromagnetic environment. There are regulations in place to ensure that devices and systems do not interfere with each other’s electromagnetic range. However, some interference may result from malicious intent. This interference can disrupt the signals, rendering the system ineffective. 

BS IEC 61000‑4‑36 provides you with tests that assess the immunity of your system from such IEMI threats. 

BS IEC 61000‑4‑36 specifies that a key requirement of developing IEMI test methods and test levels is to achieve a good understanding of the environment in which the victim equipment or system will be required to operate. Within BS IEC 61000‑4‑36 specific focus is provided for victim equipment that is integrated within a site or other fixed installation and it is generally assumed that such equipment is housed within a building. 

Using BS IEC 61000‑4‑36 you can assess the immunity of your equipment and systems, as the testing helps minimize the possibility IEMI emissions will interfere with your frequency. 

What’s changed since the last update?  

BS IEC 61000‑4‑36:2020 supersedes BS IEC 61000‑4‑36:2014. BS IEC 61000‑4‑36:2020 includes some technical changes with respect to BS IEC 61000‑4‑36:2014. These include: 

• The addition of a hyperband and mesoband radiated transients’ immunity test method in Annex H 
• Addition of a calibration method of sensors for radiated hyperband and mesoband transient fields and measurement uncertainty in Annexe I
