In addition, W586 can obtain material certification from end termination vendors. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C.

Historical Version s – view previous versions of standard. Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur. This abstract is a brief summary of the referenced standard. The stress corresponding to this load shall meet the requirements for stress at 0. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.

NOTE 1—A typical ordering description is as follows: Your comments are invited either for revision of this standard or for asgm standards and qstm be addressed to ASTM Headquarters. Users aa586 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.

Maintain this load and attach the extensometer. Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.

WW is also ISO certified. Using SS also offers these advantages: For users who opt to use SS without downsizing the diameter of the strand, other benefits a5866. Structural strand provides a high strength-to-weight ratio, a high modulus of elasticity and a small diameter-per-unit strength. Class C Coating Outer Wires Determine the load at 0. If fracture takes place outside atm middle third of the gage length, the elongation value obtained may not be representative of the material.

Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen.

Refer to Table 1 for structural strand data. A number in parentheses indicates the year of last reapproval.

For any given diameter, wire strand is the least flexible of steel cables. Originally published as A — The higher strength results in an increased design factor of the guying system. The modulus of elasticity shall be determined from gage length of not less than in.

Record the elongation attained from the elongation extensometer and add to it 0. In doing so, we are able to test and certify the following:. Specimens shall be tested and conform to values of the following physical requirements: 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.

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. Continue the application of load until fracture occurs. 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.

Joints and Splices 8. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.

The stress corresponding to this load shall meet the requirements for the stress of 0. When specied, inspection may be waived, and certied copies of test reports furnished.
