? Test Site Introduction
In 2017, NG28 Electronic Technology Division established an Automotive Electronic Components Testing Laboratory in Ningbo. Then in 2019, expanded its scale in another more comprehensive laboratory in Kunshan, which not only obtained CNAS accreditation in early 2020,but also incorporated an all-new design and materials to better provide a unique, high quality testing environment.
CTI Automotive Electronic Components Testing Laboratory provides testing services in traditional automobile parts, new energy automobile parts, and railway. In addition, it also provides clients an all-new testing environment with comprehensive technical support and high-quality service to accelerate the marketing of their products at a perfect time.
