For users who opt to use SS without downsizing the diameter of the strand, other benefits apply.

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. A superscript epsilon e indicates an editorial change since the last revision or reapproval. If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative of the material. 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 axtm.

ASTM A586 – 04a(2014)

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 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.

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. The stress corresponding to this load shall meet the requirements for stress at 0. Your comments are invited either for revision of this standard or for additional standards and astmm be addressed to ASTM Headquarters.

Ast a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. Structural strand provides a high strength-to-weight ratio, a high modulus of elasticity and a small a856 strength.

The stress corresponding to this load shall meet the requirements for the stress of 0. Using SS also offers these advantages: In addition, WW can obtain material certification from end termination vendors. Record the load for this extension. In this case the prestretching provision of the test sample of 5. The coating shall be continuous and reasonably uniform.

Refer to Table 1 for structural strand data.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Historical Version s – view previous versions of standard. 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. Two separate instruments are advisable since the more sensitive stress at 0. Joints in the wires of strand shall be dispersed sufficiently so as to maintain the minimum breaking strength as listed in Table 1 and Table 2.

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. Splicing of the inner wires during the stranding operation is permissible. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is asym. NOTE 2—The extensometer used for the stress at 0.

NOTE 1—A typical ordering description is as follows: Continue the application of load until fracture occurs. If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted. 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. When specied, inspection may be waived, and certied copies of test reports furnished.

aastm 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. Hold the specimen at 0. In doing so, we are able to test and certify the following: Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. Current edition approved April 10, In doing so, we are able to test and certify the following:.

Qstm C Coating Outer Wires ASTM B r WW is also ISO certified. Record the elongation attained from the elongation extensometer and add to it 0.

Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. A number in parentheses indicates the year of last reapproval. Then increase the load uniformly until the extension recorded by the extensometer is at least 0. 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.

It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. Any test, however, which fails due to faulty attaching of the sockets shall be disregarded. 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.
