ISO 610:1990 PDF

This International Standard specifies the requirements for a range of high-grade special purpose calibrated, high-tensile, electrically welded, steel chains (round link) for use with machines and equipment in mining, such as the following:

• conveyors, flexible and rigid, of the chain type, chain belt conveyors, gate end and stage loaders:
• coal ploughs, coal cutters and power loaders;
• bucket elevators;
• other similar machines used in mines.

This International Standard covers a size range from 14 mm to 30 mm. Three grades of quality (B, C and D) are specified with regard to the mechanical properties of chain. The values given for grade D in tables 3, 4, 7 and 8 are, however, provisional.

Chains covered by this International Standard are not designed for lifting appliances, such as cranes and slings.
