Standard Specification for Steel Wire, Cold-Drawn, for Zig-Zag, Square-Formed, and Sinuous-Type Upholstery Spring Units (Withdrawn 2008)
ABSTRACT
This specification covers round, uncoated, cold-drawn spring wire in coils intended for the manufacture of upholstery springs such as zig-zag, square-formed, and sinuous. The steel shall be made by open-heart, basic-oxygen, or electric-furnace processes. Heat analysis shall be made to determine the percentage of elements, such as carbon and manganese, present in the spring wire. Tension and wrap tests shall be done for one test specimen for each ten coils. Workmanship, inspection, packaging, product marking, and loading are also covered.
SCOPE
1.1 This specification covers round, uncoated, cold-drawn spring wire in coils having properties and quality intended for the manufacture of the following upholstery springs:
1.1.1 Type A—Zig-zag (U-formed),
1.1.2 Type B—Square-formed, and
1.1.3 Type C—Sinuous for furniture spring units.
1.2 These types of upholstery springs are used in the manufacture of automotive seat springs and furniture springs. The wire is not intended for the manufacture of mechanical springs.
WITHDRAWN RATIONALE
This specification covers round, uncoated, cold-drawn spring wire in coils having properties and quality intended for the manufacture of the following upholstery springs: Type A—Zig-zag (U-formed), Type B—Square-formed, and Type C—Sinuous for furniture spring units.
This standard is being withdrawn with no replacement because the grades listed in this specification have been incorporated into Specification A 407.
