IEC 60502-1:2004+A1:2009 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation for rated voltages of 1 kV (U_m = 1,2 kV) and 3 kV (U_m = 3,6 kV) for fixed installations such as distribution networks or industrial installations. This standard includes cables which exhibit properties of reduced flame spread, low levels of smoke emission and halogen-free gas emission when exposed to fire. Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area), submarine use or shipboard application. This consolidated version consists of the second edition (2004) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
