Hong Kong, December 14, 2020 - UL, a global safety science leader, has received approval from the Intel Corporation to conduct Thunderbolt™4 host product certification testing. The new approval status allows UL to help manufacturers and brand owners adhere to relevant interoperability requirements and confirm their compliance in the market place.

Thunderbolt 4 is the next-generation connectivity solution capable of transferring data, outputting a display and providing power. Thunderbolt 4 builds on the innovation of Thunderbolt 3 connectivity, provides a 40 Gigabits per second (Gbps) connection for data and video and also provides up to 100 watts of power over a single connection. Thunderbolt 4 is the most comprehensive Thunderbolt specification to date and complies with the broadest set of industry-standard specifications, including USB4™, DisplayPort™ and PCI Express (PCIe®) and is fully compatible with prior generations of Thunderbolt and USB products.

The current scope of UL’s testing for Thunderbolt covers electrical and functional testing on Thunderbolt 3 and Thunderbolt 4 hosts such as laptops and desktop computers.

Fred Shek, senior director of UL’s Wire and Cable division, said, “UL is excited to help companies overcome critical interoperability compliance challenges, demonstrate their performance and safety attributes, and ultimately gain confidence and trust with key industry stakeholders.”
