Ensure that the electromagnetic field transmissions of your products comply to regulatory standards
Electric, magnetic and electromagnetic fields,(EMF) represent one of the most common and fastest growing environmentalinfluences, about which concern and speculation are spreading as technology advances. Humans are exposed to a complex mix of electric, magnetic and electromagnetic fields in their daily lives. Every usage of electric energy generates emissions of electric, magnetic or electromagnetic fields. Thereby, electromagnetic field transmission for radio applications are generated by devices for radio communication or radio determination. Other devices, like microwaves, use EMF internally, but do not require external emission. Finally, there are many devices like appliances or industrial equipment that generate unwanted EMF emissions. To comply with market requirements and avoid costly recalls, manufacturers must ensure the EMF emissions are within defined regulatory limits.
What is electromagnetic field (EMF) testing?
The purpose of electromagnetic field testing is to assess electronic and electrical equipment to human exposure restrictions for electric, magnetic and electromagnetic fields. You can divide between are static, extremely low frequency and radiofrequency fields encompassing the frequency range of 0 Hz to 300 GHz. There are separate limits for occupational and general public exposure. Physical quantities measured and compared against reference levels are electric and magnetic field strength, magnetic flux density, power density and contact current. If measured quantities are higher than reference levels more detailed analysis is needed to access compliance with the basic restrictions for physical quantities including current density, internal electric field and specific absorption rate (SAR).
Why is electromagnetic field (EMF) testing important?
Over the past decade, numerous electromagnetic field sources have become the focus of health concerns, including power lines, microwave ovens, household appliances, luminaries, computer and TV screens, security devices, radars, wireless devices, mobile phones and their base stations and most recently inductive charging pads for electronic equipment or electric vehicles.
EMF compliance is a mandatory requirement in most markets including Europe, the U.S., Canada, China, Korea, Australia and New Zealand. Electromagnetic field testing is necessary to help you meet regulatory requirements, improve product safety and reduce the risk of costly non-compliance. Third-party electromagnetic field tests and conformity assessments also help to strengthen your competitive position in the market.
