Historical Version s – view previous versions of standard.
It can be furnished with Class B weight or Class Z586 weight zinc-coated outer wires where additional corrosion protection is required. 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. Work Item s – proposed revisions of this standard.
ASTM A586 – 04a(2014)
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of asgm standard. Two separate instruments are advisable since the more sensitive stress at 0. WW is also ISO certified.
Find a qstm or province to view Wirerope Works, A58. Using SS also offers these advantages: Last previous edition A — NOTE 2—The extensometer used for the stress at 0. 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.
Class B Coating Outer Wires Continue the application of load until fracture occurs. Maintain this load and attach the extensometer. The stress corresponding to this load shall meet the requirements for the stress of 0.

This abstract is a a5886 summary asrm the referenced standard. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. For any given diameter, wire strand is the least flexible of steel cables. Link to Active This link will always route to the current Active version of the standard. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen.
The hand straightening necessary to permit insertion of the specimen in the jaws of the testing machine shall be performed by drawing between wood asrm or by some other equally satisfactory means. These are the features that permit strand to adapt so successfully to structural applications.
Record the load for this extension. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. Structural 5a86 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. Specically dimensioned strand bigger than 4 in.
Current edition approved April 10, Sampling and Testing 9. Using SS also offers these advantages:. It is informational only and not an official part of the xstm the full text of the standard itself must be referred to for its use and application. Then increase the load uniformly until the extension recorded by the extensometer is at astj 0. The modulus of elasticity shall be determined from gage length of not less than in. Maintain this load while a in. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

If both of these tests pass, the coil or reel shall be accepted. In this case the prestretching provision of the test sample of 5. Welds made in the outer wires prior to drawing are permitted. Users of this standard are expressly advised that determination of the validity of any such w586 rights, and the risk of infringement of such rights, are entirely their own responsibility. 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 aetm cause for rejection.
A number in parentheses indicates the year of last reapproval. Hold the specimen at 0. For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. 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. Class C Coating Outer Wires 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.
Determine the load at 0. NOTE 1—A typical ordering description is as follows: The number of layers and number and size of wires in each layer shall be determined by the manufacturer.
Your comments are invited ast for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
Joints and Splices 8. Refer to Table 1 for structural strand data.
