25、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, lifti
26、ng 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
27、 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-,
28、two-, three-, four-leg and endless chain slings, assembled by welding, using short link grade 4 medium tolerance 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
29、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 sp
30、ecific 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. 2 Normativ
31、e 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 text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of an

48、ectly 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
49、are met. Fatigue failure has not been identified as a hazard when chain slings having the specified levels of performance given in this Part of EN 818 are used in general lifting service. Since failure can be caused by the incorrect choice of grade and specification of lifting accessories this Part of EN 818 also gives the requirements for marking and the manufacturers certificate. Errors in fitting together of welded chain slings can also lead to premature failure and this European Standard contains dimensional requirements to allow correct fit. T
