Michihisa Yamazaki, retired, co-founded A-Pex International in Japan to provide application agent services for product safety certification, where he helped to build the company into Japan’s leading provider of electromagnetic compatibility evaluation and application agent services. Michihisa joined UL in 2003 when A-Pex International and UL Japan merged to form UL Apex Company Ltd. Among his many professional accomplishments, Michihisa designed wireless testing services to expand the UL electromagnetic compatibility (EMC) service portfolio as promising new wireless technological devices emerged. As part of this effort, he worked closely with regulatory authorities in various countries, registering UL Apex testing sites to aid conformity with each new wireless standard.During his time at UL, Michihisa fostered communication with wireless control authorities in more than 80 countries for conducting EMC services. He also implemented UL certification services for conformance with wireless local area network (LAN) and Bluetooth® standards using short-range wireless technology. In addition, Michihisa led the development of specific absorption rate (SAR) testing to evaluate the effect of electromagnetic waves on human body. He was active as a standards development panel member on the Electromagnetic Information Security Committee, and the ECONET Committee. Michihisa retired in June 2007.

He is a Founding Member of the William Henry Merrill Society, and a Corporate Fellow of the William Henry Merrill Society Class of 2006.
