20、a harmonized standard providing one means of complying with the essential safety requirements of the Machinery Directive and associated EFTA regulations. The components covered by this Part of EN 1677 are normally supplied to be part of a sling, but they may also be used for other applications. In s
21、uch instances it is important that the component design is checked to ensure its fitness for the intended use. The extent to which hazards are covered is indicated in the scope. In addition, lifting equipment shall conform as appropriate to EN 292 for hazards that are not covered by this standard. 1
22、 Scope This Part of EN 1677 specifies general requirements for forged steel components of grade 8 up to 63 t WLL, mainly for use in: chain slings according to EN 818-4; steel wire rope slings according to prEN 13414-1:1999; textile slings according to EN 1492-1:2000, EN 1492-2:2000 intended for lift
23、ing objects, materials or goods. This standard does not apply to hand forged components and welded links, nor to other welded components. The hazards covered by this Part of EN 1677 are identified in clause 4. Annex A is informative, and gives the bases for calculation of tabulated values of mechani
24、cal properties. Annex B is informative, and gives an example of a designation system for forged steel lifting components of grade 8. !Annexes ZA and ZB give the relationship with EU-Directives.“ 2 Normative references This European Standard incorporates, by dated or undated reference, provisions fro
25、m other publications. These normative references are cited at 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 o

33、ral lifting service, expressed as a code. NOTE This term has the same meaning as the term maximum working load used in annex A of EN 292-2: 1991/A1: 1995. 3.2 manufacturing proof force (MPF) Force applied to the component during the manufacturing proof test. 3.3 breaking force (BF) Maximum force rea
34、ched during the static tensile test of the component, at which the component fails to retain the load. 3.4 traceability code Series of letters and/or numbers marked on a component that enables its manufacturing history, including the identity of the cast of steel used, to be traced.

37、s. 4 Hazards Accidental release of a load, or release of a load due to failure of a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. In order to provide the necessary strength and durability of components this Part of EN 1677 gives
38、requirements for the design, manufacture and testing to ensure the specified levels of performance are met. Since failure can be caused by the incorrect choice of grade and specification of component, this Part of EN 1677 also gives requirements for marking and the manufacturers certificate. Risk of
39、 injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this Part of EN 1677. Those aspects of safe use associated with good practice are given in EN 818-6:2000. Table 1 contains those hazards which require action to reduce risk identified by risk assessment as be
40、ing specific and significant for forged steel components, Grade 8.
