It establishes the product characteristics, the test methods, checking procedures to be used with the wires,
together with the ordering and delivery condition.

4.3 Appearance and condition
The wires shall not present any imperfections (roughness, sliver, seam, inclusion or cracks) liable to affect
the mechanical and/or electrical properties specified in this European Standard or to cause difficulties during
installation/operation.
The surface shall be clean and free of oxide inclusions or sulphide generated during the manufacturing
process or foreign substances such as pickling residue.
The colour of the metallic bright surface immediately after manufacturing may change due to atmospheric
influence. This is acceptable.

NOTE 1 Because of a possible link between the creep of the wires and the maximum percentage elongation at fracture
value (Table 4), the maximum elongation has been retained in this European Standard. These are indicative values
only, unless otherwise agreed between purchaser and manufacturer.
NOTE 2 The calculations used to determine the figures in Table 5 are specified in C.2. The minimum cross section of
the wire has been taken into consideration, see C.3.
NOTE 3 The minimum specified breaking load corresponds to the maximum force (F ) as defined in EN ISO 6892-1.
