The only defense reliability testing infrastructure in Korea equipped with an extra-large walk-in chamber.
We provide one-stop environmental and electromagnetic testing for large-scale weapon systems.

MIL-STD (Military Standard) is a technical standard established by the U.S. Department of Defense that regulates the technical specifications of electrical, electronic, and communications equipment used for military purposes. Because it targets military equipment, its durability and precision standards are more stringent than general standards.
