CEN/TC 168/WG 1 - Welded round steel link chains and chain slings

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.

This Part of EN 818 specifies the information on use and maintenance to be provided by the manufacturer with chain slings conforming to EN 818-4 and EN 818-5. Annex A is informative, and provides some of the detailed information for use and maintenance which may be appropriate. The hazards covered by this Part of EN 818 are identified in clause 4.

This Part of EN 818 specifies the requirements related to safety, methods of rating and testing of single-, two-, three-, four-leg and endless chain slings, assembled by welding, using short link grade 4 medium tolerance chain conforming to EN 818-3 together with the appropriate range of components of the same grade in accordance with prEN 1677-5 and 6. These chain slings are intended for lifting objects, materials or goods.  NOTE1: Instructions for use and maintenance of chain slings are covered by prEN 818-6.  The hazards covered by this Part of the standard are identified in clause 4.  Annex A gives an alternative method of rating and marking a chain sling for a specific lifting application  Annex B contains the bases for calculation of working load limits.  Annex C gives an example of a designation system for chain slings.  Annex D gives an example of identification tags for chain slings.  Annex ZA gives the relationship with EU Directives.

This Part of EN 818 specifies the requirements related to safety for short link lifting chains, Grade 4, of medium tolerance for use in chain slings and for general lifting purposes. The standard is applicable to electrically welded round steel short link chains, conforming to EN 818-1, which are intended for lifting objects, materials or goods.  The range of nominal sizes of chain covered by this Part of EN 818 is from 7 mm to 45 mm.  The hazards covered by this Part of EN 818 are identified in clause 4.  Annex A contains the bases for calculation of tabulated values for dimensions, working load limits and mechanical properties.  Annex B gives information on the mass/metre of chain.  Annex C gives an example of a designation system for chains of grade 4.  Annex ZA gives the relationship with EU-Directives

This part of EN 818 specifies the requirements related to safety for short link lifting chains, Grade 8, of medium tolerance for use in chain slings and for general lifting purposes. They are electrically welded round steel short link chains, heat treated and tested and complying with the general conditions of acceptance of EN 818-1.   The range of nominal sizes of chain covered by this part of EN 818 is from 4 mm to 45 mm.  The bases for calculation of tabulated values for dimensions, working load limits and mechanical properties are given in Annex A.  Annex B gives information on weight/metre of chain.  Annex C gives an example of a designation system for chains.

This European Standard specifies the requirements related to safety, methods of rating and testing of single-, two-, three-, four-leg and endless chain slings assembled by:    a) mechanical joining devices;   b) welding.   using short link grade 8 medium tolerance lifting chain conforming to EN 818-2 together with the appropriate range of components of the same grade.   Note: Instructions for use and maintenance of chain slings are covered by prEN 818-6.  The hazards covered by this European Standard are identified in clause 4.  Bases for the calculation of working load limits are given in Annex B.  Annex C gives an example of a designation system for chain slings.

This part of EN 818 specifies the general conditions of acceptance related to safety for electrically welded round steel short link chain for lifting purposes. It includes:    a) medium tolerance chain for use in chain slings and for general lifting service and;    b) fine tolerance chain for use with hoists and other similar lifting appliances.   The hazards covered by this part of EN 818 are identified in clause 4.  Annex C gives proposals for clauses covering inspection, inspection marking and steel makers cast analysis which may be included in a form of contract.
