IEULER Testing Center

Shanghai Techwin Science Co., Ltd. is holding company of an independent third-party laboratory nearly 1,000 square meters. As a professional Sino-German joint venture third-party testing laboratory in China, it is co-founded by Techwin, and other two Geman Company DYNA-MESS and SpineServ. They run two laboratories together—one in China (Shanghai) and one in Germany. The Shanghai laboratory is equipped with kinds of advanced facilities, including over 50 sets of imported testing instruments and sample preparation machines. Integrating the professional testing technologies support from SpineServ and more than 40 years experience of testing instruments development from DYNA-MESS, our laboratory provides standard testing and customized testing services and various R&D tests for customers, and also provides testing consulting and training.

As a technical platform, IEULER® Polymer Material Application Testing Center of Techwin focuses on the testing and R&D service for rubber and elastomers, plastics, and composite .Notably, it is the first third-party laboratory accredited by CMA (China Metrology Accreditation) in accordance with GB/T 41941-2022 (Determination of Fatigue Crack Growth Rate of Vulcanized Rubber) in China.
