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

In addition, WW can obtain material certification from end termination vendors. Last previous edition A — Joints and Splices 8.

Test for Coating Weight 6. The strand is available with parallel or helical wire construction. Strand shall a56 packaged in such a manner so that no permanent deformation of wires in the strand will occur.

These are the features that permit strand to adapt so successfully to structural applications. The number of layers and number and size adtm wires in each layer shall be determined by the manufacturer.

Specically dimensioned strand bigger than 4 in. Any test, however, which fails due to faulty attaching of the sockets shall be disregarded.

Determine the load at 0. Sampling and Testing 9. Continue the application of load until fracture occurs. NOTE 2—The extensometer used for the stress at 0. Maintain this load and attach the extensometer. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. Find a state or province to view Wirerope Works, Inc.

The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer. Referenced Documents purchase separately The documents listed below are referenced within the subject a86 but are not provided as part of the standard. Record the elongation attained from the elongation extensometer and add to it 0.

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

Splicing of the inner wires during the stranding operation is permissible. 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.

Record the load for this extension. The higher asstm results in an increased design factor of the guying system. Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section. This abstract is a brief summary of the referenced standard.

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. Originally published as A — When specied, inspection may be waived, and certied copies of test reports furnished. Welds made in the outer wires prior to drawing are permitted.

Apply a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. Using SS also offers these advantages:. If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative of the material. 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.

Historical Version s – view previous versions of standard. 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.

Then increase the load uniformly until the extensometer indicates an extension of 0. In this case the prestretching provision of the test sample of 5. Class C Coating Outer Wires Specimens shall be tested and conform to values of the following physical requirements:
