A sling cable is considered worn when abrasive wear has reduced its diameter by about one-third. This level of wear means a substantial loss of cross-sectional area, which directly lowers the cable’s strength and increases the risk of failure under load. Measuring the diameter at several points along the cable and replacing it if any section shows a one-third reduction ensures the sling can safely carry the intended weight.

Other conditions—fracture, corrosion, or kinking—indicate damage rather than wear and also require replacement, but the specified wear criterion is the 1/3 diameter reduction due to abrasive wear.
