EN 50525-2-21 applies to flexible cables, insulated with crosslinked elastomeric compound, and sheathed with either crosslinked elastomeric compound or thermoplastic polyurethane (TPU). The cables are of rated voltages Uo/U up to and including 450/750 V. The cables are intended for a variety of applications where appliances or equipment, including heavy industrial equipment, require a flexible connection to the power supply. The following particular cable types are included: - General purpose cables (RR and RN types);- Water-resistant cables (RN8 types); - General purpose cables with low temperature capability (BB and BN4 types); - TPU sheathed cables (BQ types); - High temperature cables (GG types). The maximum conductor operating temperatures for the cables in this standard are 60 °C (R types), 90 °C (B types) and 110 °C (G types).
