2. TECHNICAL REQUIREMENTS

2.1. Wire shall be manufactured in accordance with the requirements of this standard for technological regulations approved in the prescribed manner.

Wire shall be manufactured from carbon rope wire rod according to normative-technical documentation.

2.2. On the surface of wire should be free of cracks, shells, sunsets, shells and rust. Traces of copper plating technology on the surface of the wire are not allowed.

2.3. Permissible run-up temporary resistance to the rupture in the party must conform to the standards given in table.2.

2.6. Wire diameter less than 0.5 mm is subjected to a rupture test with the node. Thus the tearing force of the wire must be at least 50% of tearing force at break without knot.

For wire diameter from 0.5 mm to 0.8 mm test bend is replaced by a rupture test with the node.

2.7. Wire is manufactured in coils or on reels. Winding of wire should be carried out without entanglement of the coils and to permit free spooling of wire from the coils and coils. During the liberation from the bindings of a coil wire should be screwed to the group.

2.8. Wire on a reel should consist of one segment. The coil is allowed no more than three segments. The weight cut must conform to the standards specified in table.5.
