What is a rejection criterion for standing rope?

The rejection criterion for standing rope is based on the condition of the strands within the rope and their overall weight-bearing ability. The correct choice indicates that a rope should be rejected if there are three or more broken strands in a single lay, or two broken strands located at an end connection.

This criterion is significant because broken strands can weaken the structural integrity of the rope, leading to potential failure during use. The presence of three broken strands in one lay indicates a significant level of deterioration, which compromises the rope's load capacity and safety. Additionally, two broken strands at an end connection signifies a critical failure point, as these connections are essential for transferring loads safely and effectively.

Regarding the other options, fewer broken strands may not be sufficient to warrant rejection, as the rope might still maintain its structural integrity and safe usage. The use of these specific numbers (three broken strands in a lay and two at an end connection) reflects industry standards for ensuring the reliability and safety of lifting equipment.
