Environment

Equipped with cutting-edge facilities for vibration, shock, temperature and humidity, etc.
We provide environmental testing that complies with major international standards for defense and combat equipment.

Reliability means the ability of a part, product or system to operate under given conditions of use (operation) for a required period of time.
Reliability testing is the ability to maintain a designed function without failure (or the probability of operation). Reliability testing is designed to assess a product's lifespan or failure rate. We offer environmental testing in compliance with major international standards for defense and electronic components, equipped with cutting-edge equipment for vibration, shock, temperature, and humidity. We support reliability verification through compliance with a wide range of standards, including MIL-STD, RTCA/DO, and IEC.
