EN 818-3:1999+A1:2008 (E)
Introduction
This European Standard has been prepared to be a harmonized standard to provide one means of conforming
with the essential safety requirements of the Machinery Directive and associated EFTA regulations.
The Directive stipulates that where chain with welded links is used for lifting accessories it is to be of short link
type and for the purposes of this standard this is chain having a ratio of nominal pitch to nominal size of 3:1.
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."

4 Hazards
!Accidental release of a load, or release of a load due to" failure of lifting accessories such as chain
slings or their component parts puts at risk either directly or indirectly the safety or health of those persons
within the danger zone of lifting equipment.
In order to provide the necessary strength and durability of lifting accessories this Part of EN 818 lays down
requirements for the design, manufacture and testing to ensure that specified levels of performance are met.
