Test for Coating Weight 6. Record the elongation attained from the elongation extensometer and add to it 0. 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.
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. Please contact your WW regional sales manager or customer service representative for further information. Specimens shall be tested and conform to values of the following physical requirements: The strand is available with parallel or helical wire construction.
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.
Find a state or z586 to view Wirerope Works, Inc. NOTE 2—The extensometer used for the stress at 0. 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.
Link to Active This a86 will always route to the current Active version of the standard. Two separate instruments are advisable since the more sensitive stress at 0. Class B Coating Outer Wires 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. In this case the prestretching provision of the s586 sample of 5.
Originally published as A — Structural wire rope provides greater flexibility when compared with coarse strand constructions and is generally the structural cable of wstm where bending ability is an important requirement, such as forming flemish eye ends drop terminals. Apply a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen.
Sampling and Testing 9. Referenced Documents atsm separately The documents listed below are referenced within the subject standard but are not provided as part 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. This standard is subject to revision at any time by the responsible technical committee and ast, be reviewed every ve years and if not revised, either reapproved or withdrawn.
Joints and Splices 8. These are the features that permit strand to adapt so successfully to structural applications. If both of these tests pass, the coil or reel shall be accepted.
The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer. In doing so, we are able to test and certify the following:. 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. Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur.
For users who opt to use SS without downsizing the diameter of the strand, other benefits apply.
A86 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. 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.
Hold the specimen at 0. The stress corresponding to this load shall meet the requirements for stress at 0.
