EMC Testing
What is Electromagnetic Compatibility (EMC)
Electromagnetic compatibility, known as "EMC", is the ability of Electrical and Electronic (E&E) equipment to operate within its electromagnetic (EM) environment and with other equipment. All E&E devices have the potential to emit electromagnetic field radio frequency (RF) interference. Such interference can affect the normal operation of devices and others within their environment and is therefore subject to measurement and control.
The purpose of EMC is two-fold:
- To ensure that electronic devices operate as intended in their electromagnetic environment without causing Electromagnetic Interference (EMI) with each other (or themselves)
- To ensure that radio communications, particularly for emergency services, are protected
What is EMC testing
The purpose of EMC testing is to:
- Assess the EM Emissions (EMI) of your product; including both the frequencies and levels of EM energy generated by your product
- Assess the EM Immunity (EMS) of your product; the ability for your product’s normal operations to withstand (be immune to) EM energy which may occur within its operational environment. Intra-product EM immunity is particularly important in military and aerospace applications
We perform EMC testing to a wide range of EMC standards.
How We Can Help
Eurofins' global network of Electrical and Electronics (E&E) laboratories' experts can provide you with the necessary guidance and accredited EMC testing to identify and meet the EMC requirements to place your product(s) on your chosen markets.
The end-to end EMC testing and support solutions we offer can help you avoid the significant delays and costs in your product development programs which can arise due to unexpected electromagnetic interference. Eurofins E&E's capabilities include accredited laboratory-based EMC testing of products, and on-site testing of large equipment and fixed installations.
