31、 DIN EN 818-1:2008-12 EN 818-1:1996+A1:2008 (E) 5 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. This Directive stipulates that whe
32、re 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. Chains covered by this European Standard are divided into grades which relate to the mechanical proper
33、ties of the finished product and not simply to the strength of the material. Each grade is identified by a letter for fine tolerance chain or number for medium tolerance chain in the series: M,4; P,5; S,6: T,8; V,10 (see note 1 to table 0). The letter or number indicates the mean stress at the minim
34、um breaking force as shown in table 0. 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. !This standard is a Type C standard as s
35、tated 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 build according to the provi
36、sions of this type C standard.“ DIN EN 818-1:2008-12 EN 818-1:1996+A1:2008 (E) 6 Table 0 Basis of grade symbols Grade Fine tolerance Medium tolerance Mean Stress at the specified minimum breaking force, N/mm2M P S T V 4 5 6 8 10 400 500 630 800 1000 NOTE: Chains in all of these grades may not be the
37、 subjects of European Standards. This grading system has also been applied to hooks, links, shackles and other accessories, indicating their strength compatibility with the appropriate grade of chain. The stresses in a chain link are not uniform and at the extrados at the crown particularly, the max
38、imum fibre stress is considerably greater than the mean stress obtained by dividing the force by the total cross-sectional area of both legs of the link. DIN EN 818-1:2008-12 EN 818-1:1996+A1:2008 (E) 7 1 Scope This part of EN 818 specifies the general conditions of acceptance related to safety for
39、electrically welded round steel short link chain for lifting purposes. It includes: a) medium tolerance chain for use in chain slings and for general lifting service and; b) fine tolerance chain for use with hoists and other similar lifting appliances. The hazards covered by this Part of EN 818 are
40、identified in clause 4. Annex C gives proposals for clauses covering inspection, inspection marking and steel makers cast analysis which may be included in a form of contract. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications
41、. 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 any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For
