The surface of the wire must not have cracks or rust. The coating on the wire must be solid, without gaps and cracks visible without the use of magnifying devices.

 

Local copper surges are allowed, which increase the actual wire diameter by an amount not exceeding the positive limit deviation.

 

The adhesion of the copper coating to the steel base must be strong. The coating should not crack and peel off when the wire is coiled in six tight turns on a cylindrical mandrel with a diameter equal to four times the diameter of the coiled wire.
