Bibliography

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 818-3:1999+A1 together with the appropriate range of components of the same grade in accordance with EN 1677-5:2001+A1 and -6:2001+A1. These chain slings are intended for lifting objects, materials or goods.NOTEInstructions for use and maintenance of chain slings are covered by !EN 818-6:2000+A1".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.Annexes ZA and ZB give the relationship with EU Directives.
