UL launches human exposure testing services for automotive equipment.

UL Japan

UL Japan, Inc. (Headquarters: Ise City, Mie Prefecture, hereinafter referred to as UL Japan) will begin offering human exposure testing services for automotive equipment starting today, September 2 (Monday). In recent years, hybrid and electric vehicles have become more widespread, and it is expected that vehicles equipped with rechargeable energy storage systems will become more common in the future. In such vehicles, it is increasingly important to ensure that the electromagnetic waves emitted by onboard equipment do not adversely affect the human body, making compliance with ICNIRP guidelines essential. We have introduced the "ELT-400 Magnetic Field Exposure Level Tester" and the "Magnetic Field Measurement System 7904A-201" from the German company Narda S.T.S. This system allows for time-domain evaluation while simultaneously displaying the time variation of the magnetic field and enabling frequency analysis. The "ELT-400" alone could only perform relative measurements and magnetic field strength measurements in accordance with ICNIRP guidelines, but with the introduction of the "7904A-201," it is now possible to analyze occupancy conditions at specific frequencies as required by JASO TP-13002:2013.

Current status of SAR
Head SAR and Body SAR can be tested in the frequency range of 250MHz to 5.8GHz.

SAR Testing Equipment (Headquarters EMC Testing Laboratory / Shonan EMC Testing Laboratory) The SAR testing equipment utilizes the DASY5 from Schmid & Partner Engineering AG, which is the most trusted in the industry. We have three units at our headquarters EMC testing laboratory (Ise City, Mie) and one unit at the Shonan EMC testing laboratory (Hiratsuka City), allowing us to respond quickly with our well-equipped facilities and measurement track record. *Please feel free to contact us.*
EMC/Wireless Testing
One-stop service for on-site measurements, requests, and compliance with radio laws in various countries.

【Testing Facilities】 - Kashima EMC Testing Facility - Shonan EMC Testing Facility - Ise Headquarters EMC Testing Facility (+ Large Mobility Testing Building) - Yokowa EMC Testing Facility - Automotive Technology Center To meet the diverse needs of different products, UL Solutions offers testing through the following methods. We will propose options tailored to our internal resources and the characteristics of the products. ■ Commissioned Testing (Outsourced Testing) Customers provide their products, and our engineers conduct the testing. Since we handle all processes in-house, we can reduce the burden on our customers. ■ Witness Testing Similar to commissioned testing, our engineers perform the tests. Customers can be present during the testing process. ■ On-Site Testing For products that are difficult to transport to the testing facility, such as large equipment, our engineers will visit the factory or installation site directly to conduct the tests. *For more details, please refer to the PDF document or feel free to contact us.
