Introduction

This European Standard has been prepared to be a harmonized standard to provide one means of complying

with the essential safety requirements of the Machinery Directive and associated EFTA regulations.

The extent to which hazards are covered is indicated in the scope. In addition, lifting equipment shall conform

as appropriate to !EN ISO 12100" for hazards which are not covered by this standard.

!This standard is a Type C standard as stated in EN ISO 12100.

When provisions of this type C standard are different from those which are stated in type A or B standards, the

provisions of this type C standard take precedence over the provisions of the other standards, for equipment

that have been designed and built according to the provisions of this type C standard."

1 Scope

This Part of EN 818 specifies the requirements related to safety, methods of rating and testing of single-, two-,

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.

NOTE Instructions 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.
