UL Receives HDMI Forum Approval to Test New Ultra High Speed HDMI® Cables

Hong Kong, November 20, 2020 – UL’s Dongguan Songshan Lake laboratory testing house now offers electromagnetic interference (EMI) compliance testing for the new Ultra High Speed (UHS) High Definition Multimedia Interface (HDMI^® cables, also known as Category 3 HDMI^® cables). The new testing services help HDMI® Authorized Test Centers (ATCs), cable manufacturers, buyers and other customers confirm the EMI compliance of cables in accordance with the requirements outlined in the Ultra High Speed HDMI® Cable Certification Program.

All UHS HDMI^® cables must pass certification testing before being placed on the market. Radiation emitted by the UHS HDMI^® cable should be exceptionally low as low radiation minimizes interruption to the operation of peripheral wireless devices due to the EMI of the cable. 

Following testing, manufacturers need to affix an Ultra High Speed HDMI^® Certification Label, allowing consumers and end users to easily verify the certification status of the cable. The HDMI Forum announced recently certification labels for the UHS HDMI^® cable are available to order and industry stakeholders anticipate UHS HDMI® cables will soon appear in the market for consumers to purchase and use. 

Fred Shek, senior director of UL’s Wire and Cable division, said, “EMI compliance is an essential step for manufacturers who want to place UHS HDMI^® cables on the market. We are excited to be approved by the HDMI Forum as an EMI test house and look forward to helping businesses solve critical safety and performance challenges, confirm compliance and gain market access.”
