This part of EN 818 specifies the requirements related to safety for short link chains, grade 4, of medium tolerance for use in chain slings to EN 818-4:1996+A1 and for general lifting purposes. The standard is applicable to electrically welded round steel short link chains, conforming to EN 818-1:1996+A1, 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.
