Of course the procedures for such testing would also need to comply with the manufacturer's recommendations. The repeated testing of spreader bars and similar equipment seems to provide little more assurance of continued reliability than the visual inspections required by the various standards, including OSHA's. Properly conducted visual inspections together with the careful reporting of misuse and various damaging exposures will provide for the continued reliability of the lifting equipment. Should periodic load testing be desired, it is recommended that slings be returned to the manufacturer or equivalent entity for the conduct of detailed inspection and load tests. Only the manufacturer or equivalent entity are permitted to proof test and certify.
Certification is exclusively the right of only the manufacturer of new slings.
Repaired slings may be certified by an equivalent entity who made the repairs. This reference deals with repair of synthetic web slings. We do not do any repair on web slings. If they are bad the slings are removed from service and destroyed. All of our nylon lifting slings meet or exceed all industry and OSHA standards.
