17、ccessories - Safety”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2004, and conflicting national standards shall be withdrawn at the latest by Ma
18、rch 2004. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).

22、ith the essential safety requirements of the Machinery Directive and associated EFTA regulations. Purchasers are advised to specify in their purchasing contract that the supplier operates a quality management system applicable to this standard (e.g. ISO EN 9001) to ensure that products claimed to co
23、mply consistently achieve the required level of quality. The coefficient of utilization (Zp) used in this standard for slings with a diameter greater than 60 mm is lower than that normally used for general service wire rope slings. This is justified for the following reasons. a) Slings over 60 mm di
24、ameter are not intended for general service and are subjected to special conditions relating to design, construction, frequency of use, service and discard. b) The mass of the load is generally calculated or measured with considerable accuracy and as such slings are usually specially manufactured fo
25、r one or a limited number of special lifts. c) The lifting operation is controlled and supervised. d) The dynamic factors, e.g. shock loading, are limited. These factors reduce the unknown aspects which dictate that slings in general service require a higher coefficient of utilization; lower coeffic
26、ients have been and are used with confidence. 1 Scope This European Standard specifies the construction requirements, calculation of WLL, testing and certification of steel wire rope grommets, cable-laid grommets and cable-laid slings using strand and wire rope conforming to EN 12385-4. The hazards
27、covered by this standard are identified in clause 4. This standard covers ferrule-secured cable-laid slings up to 60mm. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriat
28、e 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.

31、the purposes of this standard the following terms and definitions apply. 3.1 wire rope grommet endless wire rope sling made from one continuous length of strand, formed to make a body composed of six strands around a strand core NOTE : The strand ends are tucked into the body forming the core, with
32、the tuck position diametrically opposite to the core butt position. 3.2 cable-laid grommet endless wire rope sling made from one or two continuous lengths of rope, formed to make a body composed of six ropes around a rope core NOTEThe rope ends are tucked into the body forming the core, with the tuc
33、k position(s) diametrically opposite to the core butt position(s). 3.3 cable-laid sling sling formed from a wire rope constructed of six unit ropes laid as outers over one core unit rope, with a termination at each end, usually in the form of a spliced eye 3.4 working load limit (WLL) maximum mass w

36、r a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. These aspects of safe use associated with good practice are given in prEN 13414-2. Table 1 contains all the hazards which require action to reduce risk identified by risk assessme
37、nt as being specific and significant for slings and their components.
