This part of EN 818 specifies the requirements related to safety for short link chains, grade 8, of medium tolerance for use in chain slings according to EN 818-4:1996+A1 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 in EN 818-1:1996+A1. The range of nominal sizes of chain covered by this Part of EN 818 is from 4 mm to 45 mm. The hazards covered by this Part of EN 818 are identified in clause 4. 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.
