This International Standard specifies requirements for fine-tolerance hoist chain of Grade T (types T, DAT and DT)

for use with manually operated or power-driven chain hoists1).

It is applicable to electrically welded, round, steel short-link chain, heat-treated and tested in accordance with the

general conditions of acceptance of ISO 1834, in the nominal chain size range from 3 mm to 22 mm.

NOTE Type T chain, but not type DAT or DT, may be used in lifting equipment other than chain hoists. Chain of grades TH

and VH, intended specifically for use in hand-operated hoists, will be the subject of future International Standards.
