IEC 61000-4-8 Power Frequency Magnetic Field Immunity Testing
Radiometrics Midwest Corporation provides IEC 61000-4-8 power frequency magnetic field immunity testing for electronic and electrical equipment at our A2LA-accredited EMC laboratory in Romeoville, Illinois.
IEC 61000-4-8 evaluates the ability of equipment to operate as intended when exposed to magnetic fields at power frequencies such as 50 Hz and 60 Hz. These fields may be produced by power systems, transformers, motors, current-carrying conductors, and other electrical equipment.
Radiometrics performs power frequency magnetic field immunity testing using the field strengths, exposure conditions, equipment orientations, and performance criteria required by the applicable product standard or customer test specification.
What Does IEC 61000-4-8 Testing Evaluate?
During IEC 61000-4-8 testing, the equipment under test (EUT) is exposed to a controlled power-frequency magnetic field while operating in a representative configuration.
The field is applied as required by the applicable standard or test plan, and the equipment may be evaluated in multiple orientations when necessary to expose different axes of the EUT.
During exposure, the EUT is monitored for unintended operation, measurement errors, display disturbances, communication problems, loss of function, or other performance changes that may affect its ability to meet the required performance criteria.
Radiometrics IEC 61000-4-8 Testing Capabilities
Radiometrics performs IEC 61000-4-8 magnetic field immunity testing on electronic and electrical equipment using test conditions established by the applicable product standard or customer test plan.
Our power frequency magnetic field immunity capabilities include:
- 50 Hz and 60 Hz power frequency magnetic field testing as applicable
- Testing at field strengths specified by the applicable product standard or customer specification
- Evaluation of required equipment orientations
- Operation and monitoring of the EUT during magnetic field exposure
- Evaluation of multiple operating modes when required
- Testing of electronic, industrial, medical, laboratory, and commercial equipment
- Engineering assistance when magnetic field susceptibility is observed
Planning an IEC 61000-4-8 Test Program
The IEC 61000-4-8 test program depends on the applicable product standard, required magnetic field strength, exposure duration, equipment dimensions, operating modes, required orientations, and equipment monitoring requirements.
The physical size and configuration of the equipment are important because the test setup must provide the required magnetic field exposure to the areas of the equipment specified by the applicable test method or product standard.
Providing the applicable standard and product dimensions before testing allows Radiometrics to determine the appropriate test configuration and develop an accurate quotation.
Information Needed for an IEC 61000-4-8 Quote
To help Radiometrics develop an accurate power frequency magnetic field immunity test program and quotation, please provide the following information when available:
- Applicable product standard or customer test specification
- Product description and model number
- Product dimensions and physical configuration
- Required magnetic field strength and exposure duration, if known
- Required equipment orientations, if specified
- AC or DC power requirements
- Required peripherals and support equipment
- Operating modes to be evaluated
- Method used to monitor equipment performance during testing
Magnetic Field Immunity Troubleshooting
If a product experiences a performance problem during power frequency magnetic field testing, Radiometrics can work with your engineering team to help characterize the susceptibility and determine which equipment orientation or operating condition is most affected.
Where practical, corrective changes can be evaluated during the test program to determine whether they improve the product’s magnetic field immunity.
