What happens to the rated load of the sling when a termination has 90% efficiency?

When a termination of a sling has 90% efficiency, it means that the ability of the sling to support weight is reduced due to the way the sling is terminated. Efficiency in this context refers to how much of the sling's original rated load capacity is retained after the termination process.

If the original rated load capacity of the sling is, for example, 1000 pounds, a termination with 90% efficiency would effectively provide support for only 90% of that rated load. Therefore, in this case, the sling would be able to support a maximum of 900 pounds after accounting for the loss in efficiency.

This reflects the reality that various factors, including bending and knotting, can reduce the strength and functionality of a sling. Thus, the rated load of the sling decreases to 90% of the original capacity when a termination has 90% efficiency.
