Overview

IEC 60114 is an IEC recommendation that specifies the electrical and mechanical properties required for heat‑treated aluminium‑magnesium‑silicon (Al‑Mg‑Si) alloy busbar material. First published in 1959 (with corrigendum incorporated), the standard defines limits for volume resistivity, tensile strength, 0.2% proof stress and elongation after fracture, plus reference physical constants at 20 °C. IEC 60114 is intended to ensure consistent performance and interchangeability of aluminium busbar material used in power distribution equipment.

Key topics and technical requirements

• Volume resistivity: maximum 0.0325 ohm·mm²/m (equivalent 19.550 ohm·cir.mil/ft) measured at 20 °C.
  • Measurements must be made between 10 °C and 30 °C and corrected to 20 °C.
  • Included measurement uncertainty up to 3 parts in 1 000.
• Tensile strength: minimum 20 kg/mm² (28 445 lb/in²).
• 0.2% proof stress: minimum 17 kg/mm² (24 175 lb/in²).
• Elongation after fracture: minimum 8%, measured on the short proportional sample A5 in accordance with ISO recommendations (L0 = 5.65).
• Reference physical properties at 20 °C (for calculations and design):
  • Density: 2.70 kg/dm³ (0.09754 lb/in³) - corrigendum clarified the correct density unit.
  • Temperature coefficient of resistance (mass): 0.0035 /°C.
  • Coefficient of linear expansion: 0.000023 /°C.

Applications

IEC 60114 applies to manufacturers, specifiers and users of aluminium busbars in electrical power systems, including:

• Switchgear and distribution panel manufacturers specifying Al‑Mg‑Si busbar materials.
• Electrical design engineers selecting conductive materials for low-loss power distribution.
• Material testing laboratories verifying compliance with resistivity, tensile and elongation requirements.
• Standards and quality managers ensuring material conformity for substations, transformers and distribution boards.

Keywords: IEC 60114, aluminium alloy busbar, Al‑Mg‑Si, volume resistivity, tensile strength, 0.2% proof stress, elongation, busbar material standard.

Related standards

• ISO recommendations referenced for tensile sample A5 testing procedures (ISO standard in preparation at time of publication).
• Users should consult applicable IEC and national standards on switchgear, busbar design and material testing for complementary requirements and test methods.
