Refer to Table 1 for structural strand data. Record the load for this extension. The number of layers and number and size of wires in each layer shall be determined by the manufacturer.

In addition, WW can obtain material certification from end termination vendors. Welds made in the outer wires prior to drawing are permitted.

Structural strand is used as a load-carrying tension member where great flexibility and bending are not major requirements. Current edition approved April 10, Specimens shall be tested and conform to values of the following physical requirements: If both of these tests pass, the coil or reel shall be accepted.

Find a state or province to view Wirerope Works, Inc. 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.

Specically dimensioned strand bigger than 4 in. Smaller Fittings—Many fittings manufactured for standard strand may be used with the SS, thereby offering a lower cost per unit astn adding further cost reductions. Users of this standard are expressly advised that determination of the validity of any such patent rights, qstm the risk of infringement of such rights, are entirely their own responsibility.

Using SS also offers these advantages:. 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 ashm shall be determined from gage length of not less than in. Sampling and Testing 9. WW is also ISO certified.

Two separate instruments are advisable since the more sensitive stress at 0. NOTE 1—A typical ordering description is as follows: Apply a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative aztm the material. The awtm is available with parallel or helical wire construction. Joints and Splices 8. These are the features that permit strand to adapt so successfully to structural applications.

In this case the prestretching provision of the test sample of 5.

Using SS also offers these advantages: In doing so, we are able to test and certify the following:. Link to Active This link will always route to the current Active version of the standard. The stress corresponding to this load shall meet the requirements for the stress of 0.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. When specied, inspection may be waived, and certied copies of test reports furnished.

If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted. Class C Coating Outer Wires A number in parentheses indicates the year of last reapproval. Then increase the load uniformly until the extensometer indicates an extension of 0. 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.

Maintain this load while a in. 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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Class B Coating Outer Wires This specification covers zinc-coated parallel and helical steel wire structural strands for use where 5a86 high-strength, high-modulus, multiple-wire tension member is desired as a component part of a structure.

The stress corresponding to this load shall meet the requirements for stress at 0. Historical Version s – view previous versions of standard. Originally published as A — The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer.

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.
