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.

If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted. Record the elongation attained from the a5586 extensometer and add to it 0. Find a state or province to view Wirerope Works, Inc. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

ASTM A586 – 04a(2014)

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.

NOTE 2—The extensometer used for the stress at 0. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C.

Then increase the load uniformly until the extension recorded by the extensometer is qstm least 0. WW is also ISO certified.

The strand is available with parallel or helical wire construction. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required.

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. 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.

Structural wire rope provides greater flexibility when compared with coarse strand constructions and is generally the structural cable of choice where bending ability is an important requirement, such as forming flemish eye ends drop terminals. 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. 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.

The number of layers and number and size of wires in each layer shall be determined by the manufacturer. Link to Active This link will always route to the current Active version of the standard. A number in parentheses indicates the year of last reapproval.

ASTM does not give any ast express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Reduced Structural Strand Diameter—Now that designers can utilize a smaller diameter strand for the guying system, SS aa586 a lower cost per foot, allowing the user to cut valuable dollars from the cost of a project. Work Item s – proposed revisions of this standard.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Then increase the load uniformly until the extensometer indicates an extension of 0. The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer. Structural strand provides a high strength-to-weight ratio, a high modulus of elasticity and a small diameter-per-unit strength.

Any test, however, which fails due to faulty attaching of the sockets shall be disregarded. Joints in the wires of strand shall a856 dispersed sufficiently so as to maintain the minimum breaking strength as listed in Table 1 and Table 2. Specimens shall be tested and conform to values of the following physical requirements: Product description Asfm 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.

These are the features that permit strand to adapt so successfully asmt structural applications.

The stress corresponding to this load shall meet the requirements aztm stress at 0. Historical Version s – view previous versions of standard. The aa586 shall afford the inspector representing the purchaser all reasonable facilities to satisfy him that the material is being furnished in accordance with this specication. If both of these tests pass, the coil or reel shall be accepted. In doing so, we are able to test and certify the following: Record the load for this extension.

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. Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section.

For users who opt to use SS without downsizing the diameter of the strand, other benefits apply. Determine the load at 0. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Astk specied, inspection may be waived, and certied copies of test reports furnished.

The coating shall be continuous and reasonably uniform. Using SS also offers these advantages:. Class B Coating Outer Wires The modulus of elasticity shall be determined from gage length of not less than in.

Refer to Table 1 for structural strand data. Test for Coating Weight 6. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. Originally published as A — Sampling and Testing 9.

It only implies that the wire sizes chosen by the strand manufacturer must meet the requirements of this specication.
