Testing and Certification of Digital and Computer-Related Products

◉    Service Background

Electromagnetic Compatibility (EMC) testing is the basis for electronic and electrical products to enter the global market. If a product is to be exported to countries or regions such as the European Union, the United States, Canada, Australia, Korea, etc., and even when marketing domestically within China, corresponding EMC tests will need to be done to meet compliance. The radiated disturbance test is one part of EMC testing.

Centre Testing International Group(CTI), a pioneer and leader in China's third-party testing and certification services,is a comprehensive third-party organization that provides a one-stop solution for testing, calibration, inspection, certification and technical services on a global scale.
