BS EN 818-7:2002+A1:2008 PDF

Scope: This European Standard specifies the requirements related to safety for hoist chain, Grade T (type T quenched and tempered and types DAT and DT case hardened), for use in serial chain hoists manual and power driven. Type DAT and type DT hoist chains possess surface hardnesses greater than core hardness and are used 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 case depth to optimise wear resistance. The standard is applicable to electrically welded round steel short link hoist chains conforming to EN 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.
