适用范围：This European Standard specifies the requirements related to safety for hoist chain, Grade T (type Tquenched and tempered and types DAT and DT case hardened), for use in serial chain hoists manualand power driven.Type DAT and type DT hoist chains possess surface hardnesses greater than core hardness and areused for power driven chain hoists to offer greater resistance to wear.Type DT hoist chain differs from DAT hoist chain in having higher surface hardness and/or greater casedepth to optimise wear resistance.The standard is applicable to electrically welded round steel short link hoist chains conforming toEN 818-1.The range of nominal size of hoist chains covered by this European Standard is from 4 mm to 22 mm.The hazards covered by this European Standard are identified in clause 4.
