About Dongtan
Dongtan laboratory (main building), established in October 2014, provides specialized services in EMC, wireless, and reliability testing.
Dongtan Services
Dongtan laboratory performs EMC testing to check for the affects of electromagnetic waves generated from electronic devices on the performance of other devices and whether the performance of these electronic devices is also affected by electromagnetic waves generated from other devices.
Our wireless device certification services are essential in protecting users from potential harm associated with unintended interaction between wireless products. We ensure the safety of people and radio wave standards to be met through wireless testing.
Our team also projects the failure-free use time of products through reliability testing and checks whether the target quality level is maintained after a specified period of time.
Through small battery and electrical safety testing, we check for possibilities of overheating, short circuit, overcharging, and the like and verify their safety through tests conducted in accordance with the safety standards of target countries before they are launched in the market.
