As early as 1992, the igus® GmbH, together with the PTB (Physikalisch-Technische Bundesanstalt) in Braunschweig, conducted measurements of the electrical surface leakage resistance for igus® e-chains® with the special material igumid GC, supplemented by additional certifications in 1998 and 1999 according to DIN 53482 and the guidelines for static electricity "ZH1/200" of the Federation of Trade Associations. In the course of further innovation, the material igumid ESD was certified by the PTB (Physikalisch-Technische-Bundesanstalt) in May 2002. In its properties the material igumid ESD combines the requirements of the ESD as well as ATEX factors. In some mechanical requirements, the igumid ESD surpasses even the standard material igumid GLW and has been tested in the igus® technical center with over 10 million cycles.
