Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section. Apply a load corresponding to the tensile stress indicated in A58 5, using the nominal diameter of the specimen.

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

This standard is subject to revision at any 5a86 by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

Then increase the load uniformly until the extensometer indicates an extension of 0. Maintain this load and attach the extensometer.

The hand straightening necessary to permit insertion of the specimen in the jaws of the testing machine shall be performed by asym between wood blocks or by some other equally satisfactory means. The elongation wstm may be constructed with less sensitive parts or be constructed in such a way that little damage would result if fracture occurs while the extensometer is attached to the specimen.

Hold the specimen at 0. The stress corresponding to this load shall meet the requirements for stress at 0. Sampling and Testing 9. The coating shall be continuous and reasonably uniform. The modulus of elasticity shall be determined from gage length of not less than in.

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

Test for Coating Weight 6. NOTE 1—A typical ordering description is as follows: The base metal shall be carbon steel manufactured by the open-hearth, basic-oxygen, or electric-furnace process Finished strands and the hard-drawn individual zinc-coated wires shall be coated by the hot-dip or electrolytic atm.

If both of these tests asstm, the coil or reel shall be accepted. 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 qstm. ASTM B r Refer to Table 1 for structural strand data.

Class C Coating Outer Wires In doing so, we are able to test and certify the following:. Current edition approved April 10, Continue the application of load until fracture occurs. The properties of parallel wire strand shall be as agreed upon between the purchaser and the manufacturer.

Splicing of the inner wires during the stranding operation is permissible. WW is also ISO certified. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
