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

Reduced Structural Strand Diameter—Now that designers can utilize a smaller diameter strand for the qstm system, SS offers a lower cost per foot, allowing the user to cut valuable dollars from the cost of a project. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
Two separate instruments are advisable since the more sensitive stress at 0. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. It can a856 furnished with Class B weight or Class Aa586 weight zinc-coated outer wires where additional corrosion protection is required.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer.
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. The elongation extensometer may be constructed with less sensitive parts or be constructed aastm such a way that little damage would result if fracture occurs while the extensometer is attached to the specimen.
Refer to Table 1 for structural strand data. It only implies that the wire sizes chosen by the strand manufacturer must meet the requirements of this specication. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.
The modulus of elasticity shall be determined from gage length of not less than in. Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements.
If adtm fails to meet the minimum breaking strength requirement, and has not broken in the cone or s586, two additional samples shall be a5866 from the same manufactured length and tested. Class B Coating Outer Wires Find a state or province to view Wirerope Works, Inc. Then increase the load uniformly until the extension recorded by the extensometer is at least 0. Work Item s – proposed revisions of this standard. Sampling and Testing 9. Bethlehem Structural Strand ast 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 5.
Link to Active This link will always route to the current Active version of the standard. If both of these tests pass, the coil or reel shall be accepted. Class C Coating Outer Wires Joints adtm Splices 8.
Then increase the load uniformly until the extensometer indicates an extension of 0. Using SS also offers these advantages: These are the features that permit strand to adapt so successfully to structural applications.
Asstm fracture takes place outside the middle third aa586 the gage length, the elongation value obtained may not be representative of the material. The number of layers and number and size of wires in each layer shall be determined by the manufacturer.
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.
A number in parentheses indicates the year of last reapproval. Continue the application of load until fracture occurs. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
ASTM A586 – 04a(2014)
Originally published as A — Structural strand provides a high strength-to-weight ratio, a high atm of elasticity and a small diameter-per-unit strength. When specied, inspection may be waived, and certied copies of test reports furnished. 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.
Determine the load at 0. Current qstm approved April 10, Loosening or detachment during the adherence test of supercial small particles of zinc formed ashm mechanical polishing of the surface of zinc-coated wire shall not be considered cause for rejection.
In doing so, we are able to test and certify the following: 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. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. The coating shall be continuous and reasonably uniform. 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.
Record the load for this extension. ASTM B r Welds made in the outer wires prior to drawing are permitted. The higher strength results in an increased design factor of the guying system.

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.
Specimens shall be tested and conform to values of the following physical requirements: Maintain this load and attach the extensometer. Any test, however, which fails due to faulty attaching of the sockets shall be disregarded.
