The stress corresponding to this load shall meet the requirements for the stress of 0.

These are the features that permit strand to adapt so successfully to structural applications. Historical Version s – view previous versions of standard. Refer to Table 1 for structural strand data.

The coating shall be continuous and reasonably uniform. Current edition approved April 10, Record the load for this extension. ASTM B r It only implies that the wire sizes chosen by the strand manufacturer must meet the requirements of this specication. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

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. S586 Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.

In this case the prestretching provision of the test sample of ashm. 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.

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. In doing so, we are able to test and certify the following:. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.


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.

In addition, WW can obtain material certification from end termination vendors. Class B Coating Outer Wires Test for Coating Weight 6. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

Originally published as A — If either additional sample fails the retest for breaking strength, the manufactured length in question shall be rejected.

Two separate instruments are advisable since the more a56 stress at 0. Welds made in the outer wires prior to drawing are permitted.

Work Item s – proposed revisions of this standard. The number atsm layers and number and size of wires in each layer shall be determined by the manufacturer. The elongation extensometer may be constructed with less sensitive parts or be constructed in such a way that little damage would result if fracture occurs while the extensometer is attached to the specimen.

Then increase the load uniformly until the extensometer indicates an extension of 0. Sampling and Testing 9. 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.

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 qstm their own responsibility. Record the elongation attained from the elongation extensometer and add to it 0.

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 aa586.

Product description Prestretching Striping Proofloading Pin orientation Certification Special features Length tolerances Galvanized coating Modulus of elasticity Length and point of measurement Measuring at required load End terminations dimensions, pin sizes, jaw openings Nondestructive test method. Maintain this load and attach the extensometer. 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.

Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. This abstract is a brief summary of the referenced standard. The higher strength results in an increased design factor of the guying system. 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 eye ends drop terminals.

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 to test and certify the following: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

ASTM A586 – 04a(2014)

The modulus of elasticity shall be determined from gage length of not less than in. Continue the application of load until fracture occurs. Joints and Splices 8. Maintain this load while a in.
