Testing textile physics and textile chemistry

With our state-of-the-art testing instruments and apparatus we conduct textile-related physical and chemical tests on fibres, single and ply yarns, woven and knitted fabrics, non-wovens and finished products. Our services also include tests related to clothing physiology on fabrics and ready-made textile products. Our portfolio also includes tests listed in the standards stipulating requirements for personal protective equipment (PPE), which also include various burning tests.

The tests are conducted mainly in conformity with EN and ISO standards. You can find the scope of the accreditation here  (STS 0228).
