Work Item s – proposed revisions of this standard. Apply a load, corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. If both of these two samples pass the retest for breaking strength, the manufactured length in question shall be accepted. Structural wire rope provides greater flexibility when compared with coarse strand constructions and astk generally the structural cable of choice where bending ability is an important requirement, such as forming flemish eye ends astj terminals.

Test for Coating Weight 6.

Continue the application of load until fracture occurs. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. NOTE 2—The extensometer used for the stress at 0.

Please contact your WW regional sales manager or customer service representative for further information. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

A number in parentheses indicates the year of last reapproval. Joints and Splices 8. The base metal shall be carbon steel manufactured by the open-hearth, basic-oxygen, or electric-furnace ast Finished strands and the hard-drawn individual zinc-coated wires shall be coated by the hot-dip or electrolytic process. In addition, WW can obtain material certification from end termination vendors. 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.

Current edition approved April 10, Last previous edition A — The strand is available with parallel or helical wire construction.

The coating shall be continuous and reasonably uniform. WW is also ISO certified. Specimens shall be tested and conform to values of the following physical requirements: Maintain this load and attach the extensometer.

Then increase the load uniformly until the extension recorded by the extensometer is at least 0. Class C Coating Outer Wires It only implies that the wire sizes chosen by the strand manufacturer must meet the requirements of this specication.

In this case the prestretching provision of the test sample of 5. 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. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C.

ASTM B r Using SS also offers these advantages:. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

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.

Class B Coating Outer Wires If both of these tests pass, the coil or reel shall be accepted. These are the features aetm permit strand to adapt so successfully to structural applications. Historical Version s – view previous versions of standard. The modulus of elasticity shall be determined from gage length of not less than in.

Using SS also offers these advantages: Record the elongation attained from the elongation extensometer and add to it 0.

The stress corresponding to this load shall meet the requirements for the stress of 0. Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur.

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 method.

Then increase the load uniformly until the extensometer indicates an extension of 0. Two separate instruments are advisable since the more sensitive stress at 0. Maintain this load while a in.
