Foreword
This document (EN 818-4:1996+A1:2008) has been prepared by Technical Committee CEN/TC 168 “Chains,
ropes, webbing, slings and accessories - Safety”, the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by October 2008 and conflicting national standards shall be withdrawn at
the latest by October 2008.
This document includes Amendment 1, approved by CEN on 2008-02-10.
This document supersedes EN 814-4:1996.
The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ".
!This document has been prepared under a mandate given to CEN by the European Commission and the

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech

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.
The Directive stipulates that where chain with welded links is used for lifting accessories it is to be of short line
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 of this Part of EN 818. In addition, lifting
equipment shall comply as appropriate with !EN ISO 12100" for hazards which are not covered by this
standard.
Annex C gives a designation system for recording the identifying features of grade 8 chain slings. Since this
system is not widely used it has been included in this first edition of this standard as an informative annex,
however should its use become more generally accepted then the status of the information would need to be
reviewed.
!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 European Standard specifies the requirements related to safety, methods of rating and testing of single-,
two-, three-, four-leg and endless chain slings assembled by:
a) mechanical joining devices;
b) welding
using short link grade 8 medium tolerance lifting chain conforming to EN 818-2 together with the appropriate
range of components of the same grade.
