What is Radiated Radio Frequency Electromagnetic Field Immunity?

Radiated RF electromagnetic field immunity, also known as radiation sensitivity, radiated immunity, or R/S, is one of the fundamental tests in electromagnetic compatibility (EMC) immunity. It refers to the ability of devices, equipment, or systems to resist interference from radiated electromagnetic fields. The higher the sensitivity, the lower the interference resistance. For example, electromagnetic fields generated by radio stations, television stations, fixed or mobile radio transmitters, and various industrial radiation sources are typically measured in the frequency range of 80 MHz to 6 GHz according to standard practices.

 

For products such as electric bicycles, electric scooters, and industrial trucks, the lower limit of the measurement frequency is extended from the conventional 80 MHz down to 20 MHz, and the field strength is increased to a maximum of 30 V/m. When operating within these electromagnetic fields, such products may be affected, potentially disrupting normal operation.

 

China JJR Laboratory operates professional testing facilities with comprehensive certifications, providing one-stop radiated immunity testing and certification services.

 

Testing and Certification Capabilities

China JJR Laboratory offers pre-tests, test reports, and certification services for electronic products requiring low-frequency radiation immunity testing as mandated by applicable standards.

 

Low-Frequency Radiation Immunity Testing Standards

European Standards

- EN 17128

- EN 15194

- EN 12895

 

UK Standards

- BS EN 17128

- BS EN 15194

- BS EN 12895

 

Field Strength of Interference Equipment (Maximum)

- 20 MHz – 100 MHz, at 3 meters: 30 V/m

 

Electrical Specifications of Tested Samples (Maximum)

- Power Port: AC 690V, 300A, single-phase/three-phase

- DC Port: DC 1800V, 30A MAX (can be increased to 200A with a customer-provided DC source)

 

Product Categories / Number of Samples

- 1 sample set (If the test fails, we can provide rectification services as needed).

 

Maximum Dimensions of Tested Products

- 1.5m (width) × 2m (height)

 

Certification Timeline

- Single Test: Test results within 3 working days. Add 2 more working days if a report is required.

- Certification: Product certification includes multiple tests, with low-frequency radiation immunity being one item. The overall timeline is generally 15 working days.

 

Certificate Validity

The validity period depends on the standard’s effective duration. If there are no significant technical changes, the certificate can be directly updated to the latest standard. Please consult technical support for details.

 

Required Documentation

- Product technical specifications.

- For complex products, a user manual and auxiliary equipment are also required.

 

Advantages of China JJR Laboratory

- Comprehensive Facilities: China JJR Laboratory offers professional testing facilities with full certifications. Whether pre-testing, obtaining certificates, or reports, we ensure timely service.

- Expert Rectification Engineers: If a product fails testing, our rectification engineers can provide technical advice and support or handle rectification directly to resolve issues effectively.
