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.
ASTM A 镀锌平行和螺旋形钢丝绳_百度文库
The modulus of elasticity shall a568 determined from gage length of not less than in. If both of these tests pass, the coil or reel shall be accepted. 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.
A number in parentheses indicates the year of last reapproval. The stress corresponding to this load shall meet the requirements for stress at 0. 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.
NOTE 2—The extensometer used for the stress at 0. In addition, WW can obtain material certification from end termination vendors. Current edition approved April 10, Apply a load corresponding to the tensile stress indicated in Table 5, using the nominal diameter of the specimen. It can be furnished with Class B weight or Class C weight zinc-coated outer wires where additional corrosion protection is required. Specimens shall be tested and conform to values aztm the following physical requirements: In doing so, we are able to test and certify the following: Last previous edition A — ASTM B r Specically dimensioned strand bigger than 4 astj.
Link to Active This link will always route to the current Active version of the standard. If fracture takes place outside the middle third of the gage length, the elongation value obtained may not be representative of the material.
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. These are the features that permit strand to adapt so successfully to structural applications. Record the load for this extension.
Continue the application of load until fracture occurs. NOTE 1—A ashm ordering description is as follows: Originally published as A — Maintain this load while a in.

Joints and Splices 8. Using SS also offers these advantages:. 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. Maintain this load and attach the extensometer.
For any given diameter, wire strand is the least flexible of steel cables. The stress corresponding to this load shall meet the requirements for the stress of 0. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

The elongation extensometer 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. Find a state or province to view Wirerope Works, W586. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Sampling and Testing 9.
This abstract is a brief summary of the referenced standard. If it fails to meet the minimum breaking strength requirement, and has not broken in the cone or grips, two additional samples shall be cut from the same manufactured length and tested.

Welds made in the outer wires prior to drawing are permitted.
