The wires shall be of aluminium-zirconium alloy having a composition appropriate to the

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

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.
