The stress corresponding to this load shall meet the requirements for the stress of 0. NOTE 1—A typical ordering description is as follows: NOTE 2—The extensometer used for the stress at 0.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Specimens shall be tested and conform to values of the following physical requirements: Record the elongation attained from the elongation extensometer and add to it 0. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. Hold the specimen at 0. The coating shall be continuous and reasonably uniform.

If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative of the material. Structural strand provides a high strength-to-weight ratio, a high modulus of elasticity and a small diameter-per-unit strength. Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur.

This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and a56.


Galvanized Structural Strand ASTM A586

Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. Using Awtm also offers these advantages: Link to Active This link will always route to the current Active version of the standard. Joints and Splices 8. Smaller Fittings—Many fittings manufactured for standard strand may be used with the SS, thereby offering a lower cost per unit and adding further cost reductions.

Structural wire rope provides greater flexibility when compared with coarse strand constructions and is generally the structural cable of choice where bending ability is an important requirement, such as forming flemish aa586 ends drop terminals.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

A number in parentheses indicates the year of last reapproval.

If both of these tests pass, the coil or reel shall be accepted. The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer. Structural strand a856 used as a load-carrying tension member where great flexibility and bending are not major requirements.

Current edition approved April 10, The strand is available with parallel or helical wire construction.

If it fails to meet the minimum breaking strength requirement, and has not broken in the cone or grips, two additional samples shall be cut from the same manufactured length and tested. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. The modulus of elasticity shall be determined from gage length of not less than in.

In doing so, we are able to test and certify the following:. Maintain this load while a in. Last previous edition A — The higher strength results in an increased design factor of the guying system.

This specification covers zinc-coated parallel and helical steel wire structural strands for use where a high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure. Specically dimensioned strand bigger than 4 in. Class B Coating Outer Wires Loosening or detachment during the adherence test of supercial small particles of zinc formed by mechanical polishing of the surface of zinc-coated wire shall not be considered cause for rejection.

It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. The base metal shall be carbon steel manufactured by the open-hearth, basic-oxygen, or electric-furnace process Finished strands and the hard-drawn individual asm wires astmm be coated by the hot-dip or electrolytic process. Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.

The manufacturer shall afford the inspector representing the purchaser all reasonable facilities to satisfy him that the material is being furnished in accordance with this specication.
