180 years of TESTEX: From Zurich silk testing to global certification
For 180 years, TESTEX has developed alongside the textile industry while maintaining the same underlying purpose: creating trust through independent and reliable measurement. Founded in Zurich in 1846 as the Zurich Silk Conditioning Institute, TESTEX has grown from a local institution serving the silk trade into an international Swiss testing and certification institute for textiles and leather.
