19、results do not satisfy the specification requirements.3.2.6 retest, nadditional test, or tests, made when theoriginal test results do not satisfy the specification require-ments and the failure is due to a mechanical condition of thetest specimen.3.2.7 roll former, nthe organization that produces th
20、ecold-formed members.3.2.8 zinc-iron alloy, na dull grey coating with no spanglepattern that is produced on hot-dip zinc-coated steel sheet.3.2.8.1 DiscussionZinc-iron alloy-coating is normallydull gray in appearance when produced by the manufacture ofthe coated sheet. Typically, the coating contain
21、s between 8 and12 % iron, which is the result of a diffusion reaction betweenthe steel sheet and the zinc coating during the coating process.In most applications, this product is intended to be painted. Thecoating offers excellent paint adhesion. When the product isexposed to the environment without
22、 a paint coating, there is atendency for the development of a rust-colored stain on thesurface. This is caused by the presence of iron in the coating.This stain may be aesthetically objectionable to some users ofcold formed framing members.3.2.9 aluminum coating type 1, na coating of aluminumand sil
23、icon alloy on steel sheet.3.2.9.1 DiscussionAluminum-coated steel sheet type 1provides protection from corrosion primarily through thebarrier action of the coating. The aluminum-silicon alloycoating provides galvanic corrosion only in marine environ-ments. Because this coating does not generally pro
24、vide gal-vanic protection, rust staining may be evident at area where thebase metal is exposed to the environment, such as at punch-outs, cut or sheared edges of members, and at scratches.3.2.10 aluminum coating type 2, na coating of commer-cially pure aluminum on steel sheet.3.2.10.1 DiscussionAlum
