Current status of SAR
Head SAR and Body SAR can be tested in the frequency range of 250MHz to 5.8GHz.
SAR (Specific Absorption Rate) refers to the specific absorption rate of electromagnetic wave energy applied to certain parts of the human body. SAR testing includes Head SAR testing for the head and Body SAR testing for the torso (excluding the head). Initially, the main testing focused on Head SAR testing for electromagnetic wave energy applied to the head, such as from mobile phones and cordless phones. However, with the increase in wireless devices other than mobile phones, there has been a growing demand for Body SAR testing for the torso (excluding the head), particularly in the United States. UL Japan has introduced DASY5, which can test Head SAR and Body SAR in the frequency range of 250 MHz to 5.8 GHz. Additionally, we provide mobile device test sets to test mobile terminals and information devices that use GSM, CDMA, and LTE standards.

[Notice] We have started certification testing services for devices equipped with the core technology of next-generation communication, Time Averaged SAR (TAS) functionality.
UL, a third-party safety science organization in the United States, provides regulatory compliance testing and certification support for wireless communication devices and other products not only in Japan but also in countries around the world. As part of this business, we have launched certification testing services for next-generation communication core technology, specifically for models equipped with Time Average Power Control (TAS), at our headquarters EMC testing laboratory in Ise City, Mie Prefecture. With the increasing number of products equipped with TAS to comply with human exposure standards for evolving communication technologies, this technology, also known as time-averaged power control, reduces the average output of radio waves by varying the transmission state without compromising communication quality. Compliance testing for radio wave regulations in various countries for products equipped with TAS could not be conducted with conventional measurement equipment; however, we have now introduced new testing facilities capable of measuring TAS-equipped devices and have commenced certification testing services for these models. In addition to existing radio wave utilization equipment, we will provide regulatory compliance testing services for radio wave utilization devices, including those equipped with TAS, and will continue to expand our certification coverage to North America (FCC, ISED), Europe (CE Marking), Japan (Radio Law), and beyond.

UL launches human exposure testing services for automotive equipment.
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.
