About ²ÝÁñÉçÇø Yongin – Unhak 2

Opened in June 2021, Unhak 2 laboratory in Yongin, South Korea, provides specialized services in EMC, wireless communication, reliability testing, and overseas and domestic certification.

Unhak 2 Services

We offer local and international wireless and communication testing services from development to certification for wired/wireless communication devices through electromagnetic interference and immunity tests. Through pre-testing, we help customers shorten the approval period by resolving potential problems in advance. Our team also conducts reliability tests, which are often requested by importers and manufacturers separate to the standard certification for import and export and serve as standards for quality verification. We also provide certification services for standards and regulations including electrical safety, wireless, EMC, energy efficiency, and hazardous substance analysis, which we can offer for over 200 different countries.

The laboratory’s range of services includes:
