Wrapping Test

1) A test which consists of coiling the wire a given number of times, over a mandrel of its own diameter and then un­coiling. The usual test is to wrap eight turns and unwrap seven. The wire must not frac­ture and the surface must remain free of imperfections. 2) A test to evaluate the adherence of zinc coating on galvanized wire; in this case the wire is usually wound over a mandrel larger than its own diameter.
