IEULER Testing Center<\/h1><\/div>[vc_column_text]Shanghai Techwin Science Co., Ltd. is holding company of an independent third-party laboratory<\/b> 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 <\/b>SpineServ<\/b>. They run two laboratories together\u2014one 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<\/b> and sample preparation machines. Integrating the professional testing technologies support from SpineServ and more than 40 years experience of testing instruments development <\/b>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.<\/p>\n

 <\/p>\n

As a technical platform, IEULER\u00ae Polymer Material Application Testing Center of Techwin focuses on the testing and R&D service for rubber <\/b>and elastomers, plastics, and composite<\/b> .Notably, it is the first third-party laboratory accredited by CMA (China Metrology Accreditation) <\/b>in accordance with GB\/T 41941-2022 (Determination of Fatigue Crack Growth Rate of Vulcanized Rubber) <\/b>in China.[\/vc_column_text][vc_empty_space][vc_single_image image=”3200″ img_size=”full” alignment=”center”][vc_empty_space][vc_empty_space][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space]
