Originally published as A — Please contact your WW regional sales manager or customer service representative for further information.

Strand shall be packaged in such a manner so that no permanent deformation of wires in the strand will occur. Breaking strength is expressed as Grade 1 or 2, while, coating weight is expressed as Class A, B, or C. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.

Any test, however, which fails due to faulty attaching of the sockets shall be disregarded. NOTE 1—A typical ordering description is as follows: The modulus of elasticity shall be determined from gage length of not less than in. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Joints and Splices 8.

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.


The stress corresponding to this load shall meet the requirements for the stress of 0. Find a state or province to view Wirerope Works, Inc.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Using SS also offers these advantages:. 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 properties of parallel wire strand shall asfm as agreed upon between the purchaser and the aatm.

Two separate z586 are advisable since a5586 more sensitive stress at 0. Structural wire rope provides greater flexibility when compared with coarse strand constructions and is generally the structural cable of choice where bending ability is an important requirement, such as forming flemish eye ends drop terminals. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Last previous edition A — Link to Active This link will always route to the current Active version of the standard. For any given diameter, wire strand is the least flexible of steel cables.

Bethlehem Structural Strand is an arrangement of wires laid helically around a center wire to produce a symmetrical cross section. A number in parentheses indicates the year of last reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

WW is also ISO certified. ASTM B r The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned asgm this standard. Hold the specimen at 0. Class C Coating Outer Wires This abstract is a brief summary of the referenced standard. Refer to Table 1 for structural strand data. Using SS also offers these advantages: When specied, inspection may be waived, and certied copies astmm test reports furnished.


If either additional sample fails the retest for breaking strength, the manufactured length in question shall be rejected.

Test for Coating Weight 6. In doing so, we are able to test and certify the following: 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.

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.

Specimens shall be tested and conform to values of the following physical requirements: In addition, WW can obtain material certification from end termination vendors.
