6.1 Material
The wires shall be of aluminium-zirconium alloy having a composition appropriate to the
mechanical, electrical and thermal-resistant properties specified hereunder for type AT1, AT2,
AT3 and AT4, respectively. The supplier should provide the purchaser on request with the
analysis certificate of the raw material.
6.2 Freedom from defects
The wires shall be smooth and free from all imperfections such as cracks, roughness, grooves,
inclusions or other defects which may endanger the performance of the product.
6.3 Diameter and tolerance on diameter
The nominal diameter of the wires shall be expressed in millimetres to two decimal places.
Each measured value of wire diameter shall not depart from the nominal diameter by more
than the amounts given in Table 2.
For the purpose of checking compliance with the above requirement, the diameter shall be
determined by the mean of the two measurements at right angles taken at the same
cross-section.

6.4 Tensile stress
The wire shall comply with the requirements given in Table 3. The tensile stress of a single
wire shall be computed by dividing the breaking load by the cross-sectional area. The
cross-sectional area shall be determined using the measured diameter of the test specimen.
For non-round wire, shaped before stranding, its equivalent diameter of the round wire with
the same section shall be used and the calculation result of tensile stress shall comply with
the requirements given in Table 3.
The tensile stress of the non-round wire shaped during stranding may be measured after
un-stranding, whose value shall be not less than 95 % of the applicable stress requirements
given in Table 3.
6.5 Elongation
Each measured value of wire elongation shall not be less than the amounts given in Table 3.
