SEIKO EPSON CORPORATION SEIKO EPSON EMC Testing Gr

Shiojiri-shi Nagano, Japan

Seiko Epson Corporation operates an in-house EMC Testing Group at its Hirooka facility in Shiojiri-shi, Nagano, Japan, supporting compliance testing for Epson products such as printers, projectors, wearables, and semiconductor devices. The facility has historically held NVLAP accreditation (Lab Code 200157-0) along with recognition under VCCI (Japan), NMi (Netherlands), and NEMKO (Norway) programs, and operates multiple semi-anechoic chambers. As an internal corporate test facility rather than a commercial third-party lab, it primarily serves Seiko Epson's own product certification needs and is not generally available to outside customers.
