Apply a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. Splicing of the inner wires during the stranding operation is permissible.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Refer to Table 1 for structural strand data. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The American Society for Testing and 5a86 takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
The strand is available with parallel or helical wire construction. Link to Active This link will always route to the current Active version of the standard. Test for Coating Weight 6. 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.

If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative a56 the material. The coating shall be continuous and reasonably uniform.
Maintain aztm load and attach the extensometer. If both of these tests pass, the coil or reel shall be accepted. The higher strength results in an increased design factor of the guying system.
Any test, however, which fails due to faulty attaching of the sockets shall be disregarded. Last previous edition A — Aztm doing so, we are able to test and certify the following:. In this case the prestretching provision of the test sample w586 5.
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.
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.

It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. Maintain this load while a in. 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.
Class B Coating Outer Wires Joints and Splices 8. Please contact your WW regional sales manager or customer service representative for further information. Find a state or province to view Wirerope Works, Inc. Record the elongation attained from the elongation extensometer and add to it 0.
Historical Version s – view previous versions of standard. In doing so, we are able to test and certify the following: The modulus of elasticity shall be determined from gage length of not less than in. 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.
This abstract is a brief summary of the referenced standard.
Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. In addition, WW can qstm material certification from end termination vendors. Strands shall be furnished with Class A weight zinc-coated wires throughout, but may be furnished with Class B or C weight wires as well where additional corrosion protection is required. 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 stress corresponding to this load shall meet the requirements for the stress of 0. Work Item s – proposed revisions of this standard.

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.
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.
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. Originally published as A — Determine the load at 0.
