1.The zinc coating shall remain adherent when the wire is wrapped at a rate of not more than 15 turns per minute in a close helix of at least 2 turns around a cylindrical mandrel of the diameter specified in Table 3. The zinc coating shall be considered as meeting this requirement if, when the wire is wrapped about the specified mandrel, the coating does not flake and none of it can be removed from the wire by rubbing with fingers. Loosening or detachment during the adhesion test of superficial, small particles of zinc formed by mechanical polishing of the surface of zinc-coated wire shall not be considered cause for rejection.
2.1 Size- -The size of the zinc-coated wires shall be expressed as the diameter of the wire in decimal fractions of an inch or (millimetres).
2.2 Permissible Variations- -The permissible variations of the zinc-coated wire from the nominal diameter shall be as specified in Table 4.
2.3 The surface of the wire shall be free from injurious scale, flaws, splits, and other imperfections not consistent with good commercial practice. The coating shall be continuous and reasonably uniform.
3.1 Unless otherwise specified in the contract or purchase order, the manufacturer is responsible for the performance of all inspection and test requirements specified in this standard.

The purchaser shall have the right to perform any of the inspections and tests set forth in this standard when such inspections and tests are deemed necessary to assure that the material conforms to prescribed requirements.
4.2 Failure of any of the test specimens to comply with the requirements of this specification shall constitute grounds for rejection of the lot represented by the specimen. The lot may be resubmitted for inspection by testing every coil for the characteristics in which the specimen failed, and sorting out the
defective coils.
3.4 The finished zinc-coated wire shall be furnished in compact coils reasonably symmetrical in shape. The weight,inside diameter, and method of banding of the coils shall be agreed upon between the manufacturer and the purchaser.ASTM A411 pdf download.
