Bibliography

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.
