ISO 4347:2004

Leaf chains, clevises and sheaves — Dimensions, measuring forces and tensile strengths

ISO 4347:2004 specifies the characteristics of chains used for general lifting purposes, together with the rim profiles of sheaves and the chain attachment ends of clevises. It gives dimensions, limits for interchangeability, length measurement, preloading and minimum tensile strengths. It is not applicable to 8 x 8 lacing.
