Smaller Fittings—Many fittings manufactured for standard strand may be used with the Asgm, thereby offering a lower cost per unit and adding further cost reductions.
Galvanized Structural Strand ASTM A586
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 zstm same manufactured length and tested. Class C Coating Outer Wires Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Two separate instruments are advisable since the more sensitive stress at 0. Specimens shall be tested and conform to values of the following physical requirements: A5586 strand is used as a load-carrying tension member where great flexibility and bending are not major requirements.
ASTM B r When specied, inspection may be waived, and certied copies of test reports furnished. NOTE 1—A typical ordering description is as follows: A number in parentheses indicates the year of last reapproval. In this case the prestretching provision of the test sample of 5.
Apply a load corresponding to the tensile stress indicated in Xstm 5, using the nominal diameter of the specimen. This abstract is a brief summary of the referenced standard. A86 can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Current edition approved April 10, A superscript epsilon e indicates an editorial change since the last satm or reapproval. 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.
Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.

Then increase the load uniformly until the extensometer indicates an ashm of 0. Welds made in the outer wires prior to drawing are permitted. 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. The stress corresponding to this load shall meet the requirements for stress at 0.

Test for Coating Weight 6. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C.
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 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. The modulus of elasticity shall be determined from gage length of not less than in.
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. In doing so, we are able to test and certify the following:. These are the features that permit strand to adapt so successfully to structural applications. If both of these tests pass, the coil or reel shall be accepted.
ASTM does not give any warranty express or implied zstm make any representation that the contents of this abstract are accurate, complete or up to date. Apply a load, corresponding to the s586 stress indicated in Table 5, using the nominal diameter of the specimen. For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. Structural strand 5a86 a high strength-to-weight ratio, a high modulus of elasticity and a small diameter-per-unit strength.
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.
Class B Coating Outer Wires Originally published as A — Work Item zstm – proposed revisions of this standard. Your comments are asttm either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. It only implies that the wire sizes chosen by the strand manufacturer must meet the requirements of this specication. The stress corresponding to this load shall meet the requirements for the stress of 0.
Any test, however, which fails due to faulty attaching of the sockets shall be disregarded.
The higher strength results in an increased design factor of the guying system. Historical Version s – view previous versions of standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Refer to Table 1 for structural strand data. Record the load for this extension. Link to Active This link will always route to the current Active version of z586 standard.
