DIN EN 818-4:2008-12 EN 818-4:1996+A1:2008 (E) 5 Introduction This European Standard has been prepared to be a harmonized standard to provi

32、de 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

33、 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 i

34、dentifying 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

35、 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

36、 according to the provisions of this type C standard.“ DIN EN 818-4:2008-12 EN 818-4:1996+A1:2008 (E) 6 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 j

37、oining 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. !deleted text“ The hazards covered by this European Standard are identified in clause 4. Bases for the calculation of working

38、 load limits are given in annex B. Annex C gives an example of a designation system for chain slings. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the te
