The Institute for Standardization of Bosnia and Herzegovina, through its Technical Committee BAS/TC 30, has adopted the second edition of BAS EN 50525-2-21: 2019, Electric cables - Low voltage energy cables of rated voltages up to and including 450/750 V (Uo/U) - Part 2-21: Cables for general applications - Flexible cables with crosslinked elastomeric insulation by the translation method.

BAS EN 50525-2-21: 2019 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 U0/U up to and including 450/750 V.

The cables are intended for a variety of applications where applicances or equipment, including heavy industrial equipment, require flexible connection to the power supply.

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).

The following particular cable types are included:

- general purpose cables (RR and RN types);

- water-resistant cables (RN8 types);

- general purpose cables (BB and BN4 types);

- TPU sheathed cables (BQ types);

- Heat resistant cables (GG types).

BAS EN 50525-2-21 should be read in conjunction with BAS EN 50525-1, which specifies general requirements.

The original texts of the European standards were prepared by the CENELEC Technical Committee TC 20, Electric cables.
