It depends on the type of damage. Slings with a damaged outer sheath but an intact load-bearing polyester or UHMWPE core can often be re-sheathed and returned to service at their original WLL — after proof load testing. Slings with cuts, tears, or damage to the core filaments must be permanently retired and destroyed. FRT's technicians assess each sling individually and provide a written recommendation. We never return an unsafe sling to service.

A proof load test involves applying a load of 2x the sling's Working Load Limit (WLL) to verify its structural integrity before returning to service. For example, a 2-tonne WLL sling is tested to 4 tonnes. Proof load testing is required by MOM before a repaired or re-sheathed sling can be used again. FRT performs proof load tests at our Singapore facility using a calibrated test bed and issues a Certificate of Test endorsed by a MOM-accredited Professional Engineer or Authorised Examiner.

FRT's standard turnaround for sling inspection and re-sheathing is 2–5 working days from receipt of the slings at our Singapore facility. This includes visual inspection, re-sheathing, proof load testing, and certificate issuance. Rush turnaround is available for urgent compliance deadlines — contact us to discuss availability.

Both types are inspected against EN1492-1 (webbing slings) or EN1492-2 (round slings) retirement criteria. For webbing slings, inspectors look for cuts, abrasion through yarns, heat or chemical damage, distorted hardware, and illegible labels. For round slings, the outer protective sheath is examined - if the sheath is damaged, the core must be inspected before a re-sheathing decision is made. FRT is experienced in both types, as we manufacture both webbing and round slings in-house in Singapore.
