BS 2902:1957

Materials, dimensions, tests for chain slings with higher tensile strength than BS 781. Sizes of short link chain ¼ in to l½ in. Single, two-leg, three-leg, four-leg slings; reevable, non-reevable collar slings; components. Notes on design, with simple formulae for calculating proof loads for rings, links and other intermediate components. Testing machine, details of proof testing and proof loads, a form of certificate of test and examination, recommendations for safe working loads, and for use, c are and maintenance of chain and chain slings, safe working loads for alternative rings.
