Maintain this load while a in. The number of layers and number and size of wires in each layer shall be determined by the manufacturer. Work Item s – proposed revisions of this standard.

Originally published as A — Then increase the load uniformly until the extensometer indicates an extension of 0. Link to Active This link will always route to the current Active version of the standard.

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. Class C 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. WW is also ISO certified. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen.

NOTE 2—The extensometer used for the stress at 0. For any given diameter, wire strand is the least flexible of steel cables.

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 zinc-coated wires shall be coated by the hot-dip or electrolytic process. Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur.

Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. 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. Strands shall be furnished with Class A weight zinc-coated wires throughout, but may be furnished with Class B or C weight wires as well where additional corrosion protection is required.

The hand straightening necessary to permit insertion of the specimen in the jaws of the testing machine shall be performed by drawing between wood blocks or by some other equally satisfactory means. Reduced Structural Strand Diameter—Now that designers can utilize a smaller diameter strand for the guying system, SS offers a lower cost per foot, allowing the user to cut valuable dollars from the cost of a project.

For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. NOTE 1—A typical ordering description is as follows: If wstm of these tests a56, the coil or reel shall be accepted. Using SS also offers these advantages:. Record the elongation attained from the elongation extensometer and add to it 0. The stress corresponding to this load shall meet the requirements for stress at 0. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

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 application. Hold the specimen at 0. Joints and Splices 8. Bethlehem Structural Wire Rope consists of six strands made from zinc-coated wire with strands laid helically around a core, such as another strand or smaller wire rope.

The stress corresponding to this load shall meet the requirements for the stress of 0. 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. The higher strength results in an increased design factor of the guying system.

Determine the load at 0.

Then increase the load uniformly until the extension recorded by the extensometer is at least 0. Test for Coating Weight 6. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.

Using SS also offers these advantages: It only implies that the wire sizes chosen aa586 the strand manufacturer must meet the requirements of this specication.

The values given in parentheses are mathematical conversions to SI units a5866 are provided for information only and are not considered standard. Specically dimensioned strand bigger than 4 in. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. In doing so, we are able to test and certify the following:.

If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted. In doing so, we are able aztm test and certify the following: If it fails to meet the minimum breaking strength requirement, and has not broken in the cone or grips, two additional a5866 shall be cut from the same manufactured length and tested. Joints in the wires of strand shall be dispersed sufficiently so as to maintain the minimum breaking strength as listed in Table 1 and Table 2.

These are the features that permit strand to adapt so successfully to structural applications.
