Standard Test Method for Tension Testing of Wire Ropes and Strand

Importancia y uso:

4.1 Tension tests are generally to be performed on new wire ropes. The use of wire rope in any application can reduce individual wire strengths due to abrasion and nicking that will result in the wire rope strength being reduced. Damage to the outer wires will also lower the maximum strength achieved during tension testing.

4.2 The modulus of elasticity of wire rope is not considered to be a standard requirement at this time. The determination of this material property requires specialized equipment and techniques.

4.3 Rope to be tested should be thoroughly examined to verify that no external wire damage is present. If present, it should be noted. When possible, a new undamaged sample should be obtained for testing.

4.4 End attachments and their installation can directly affect breaking force achieved during testing. Any attachment that can be used to directly achieve the required rope breaking force can be used. Standard testing with a poured socket, using zinc, white metal or thermoset resin, has been considered the most efficient. Proficiency in attachment of any fitting can have a direct effect on the final test results.
