任何電子設備之間的意外干擾以及設備的輻射都會對電子設備或無線電系統產生負面影響。新產品在上市之前要達到電磁相容性 (EMC) 要求,更不要說這在很多國家是强制性的。目前,還沒有通用的 EMC 標準;每個國家的 EMC 要求可能有所不同;設備製造商需要掌握法規變化,以確保順利地進入市場。例如,之前符合 EMC 指令 (EMCD) 的廣播接收器等無線電設備需要過渡至新的無線電設備指令 (RED),才能在歐盟出售。
UL 在幫助銷售商開展合規及認證前測試方面有二十多年的經驗。認證前測試能在產品設計階段發現並解决潛在的設計漏洞,並提高實際合規測試的成功率。


Our full-service EMC laboratories are accredited by numerous regulatory agencies, governments, and the International Laboratory Accreditation Cooperation (ILAC) — making us a recognized Accreditation Body in all major markets. We can perform EMC testing to the requirements of regulatory agencies, such FCC in the USA, ISED in Canada, and similar bodies in Japan, Singapore and Korea.

Having access to EMC test laboratories that are equipped with state-of-the-art technology for emission and immunity testing allows us to analyze the ability of your electronic devices to operate as expected in proximity to other electronic devices or in the presence of electromagnetic emissions. Through these analyses, you can gain access to a whole new global marketplace.

We can tailor EMC test methodology and documentation to your own specifications, as well as offer expert advice to help ensure the most efficient use of your time and budget. Leveraging our expertise during the development process can help you avoid costly errors in the design phase and speed time-to-market.

Auto industry specific benefits

Vehicle electronic subassemblies and components pose unique testing challenges to recreate the in-vehicle device operation and monitor performance in a laboratory setting. Our expert engineers assist automotive suppliers with original equipment manufacturer (OEM) recognized EMC validation testing of varied component types, such as switches, motors, electronic control units (ECUs), lighting assemblies, electric vehicle (EV) battery control modules and even complex infotainment modules to meet OEM testing requirements.

To help you gain access to the European market, we are authorized to test automotive electronic/electric subassemblies (ESAs)for compliance with the Vehicle Type Directive and the E Mark certification of components.

We can advise you on whether a product is an immunity-related device (integral to the working of the vehicle), which may need additional testing in order to gain market approval.

Medical industry-specific benefits

For medical products, IEC 60601-1-2 fourth edition has significant changes that impact both testing and risk management related to basic safety and essential performance. On December31, 2018, this standard became mandatory for new product submittals to the U.S. Food and Drug Administration and medical products entering the European Union. This standard requires that risks resulting from reasonably foreseeable electromagnetic disturbance be taken into account in the risk management process and references ISO 14971, Medical Devices – Application of Risk Management to Medical Devices.
