DIN EN 818-5:2008-12 EN 818-5:1999+A1:2008 (E) 5 Introduction This European Standard has been prepared to be a harmonized standard to provide one means of complying with the
31、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 standar
32、d 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 b
33、uilt 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-, three-, four-leg and endless chain slings, assembled by welding, using short link grade 4 medium tolerance chain confor
34、ming 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 !E
35、N 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
36、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. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These nor
37、mative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated re
