IEC 60855-1:2016 is applicable to insulating foam-filled tubes and solid rods, of a circular cross-section, made of synthetic materials with reinforced fibreglass and intended to be used in the manufacture and construction of tools, devices and equipment for carrying out live working on electrical systems operating at voltages above 1 kV. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision.
