A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Management Centre has the same status as the officialversions. This European Standard shall be given the status of a national standard, either by publication stadard an identical text orby endorsement, at the latest by Februaryand conflicting national standards shall be withdrawn at the latestby February For relationship with EC Directives, see informative standxrd ZA, which is an integral part of this document.
The other Parts of this European Standard are: Specification for information for use and maintenance to be provided by the manufacturerPart 3: Grommets and cable-laid slingsThis is the first edition of this Part of this standard.
Annexes A and B are informative. This document includes a Bibliography. Foreword to amendment A1This document EN While producing this standard it was assumed that negotiation occurs between the manufacturer and the user todecide whether sling eyes are to be spliced or ferrule-secured and whether a thimble is to be fitted. For endlessslings it sttandard assumed that negotiation occurs to decide whether the interlapping rope ends are to be spliced orferrule-secured. Purchasers are advised to specify in their purchasing contract that the supplier operates a certified qualityassurance system applicable to this standard e.
EN Tsandard to ensure that products claimed to complyconsistently achieve the required level of quality. It covers stxndard, two- three- and four-leg slings, withferrule-secured or spliced eye terminations and spliced or ferrule-secured endless slings made from 8 mm to 60mm diameter 6 strand ordinary lay steel wire rope with fibre or steel core and 8 strand ordinary lay steel wire ropewith a steel core conforming to EN The standard assumes a working coefficient factor of safety of five.
This standard does not cover slings for single use, i. This standard does not cover matched sets of slings with spliced eyes. This document is not applicable to slings which are manufactured before the date of publication of this document byCEN.
The hazards covered by this Part of EN are identified in clause 4. These wire rope slings are intended for lifting objects, materials or goods. Guidance on the information which should be provided with an enquiry or order is given in annex A.
NOTE Information for use and maintenance, including operating temperature ranges, is given in Part 2 of this standard. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter.
Fordated references, vs amendments to or sgandard of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies including amendments.

Table 1 contains those hazards that require action to reduce risk identified by risk standadd as being specificand significant for wire rope slings.
The minimum length of plain rope between the inside ends of ferrules terminating a sling leg shall be 20 times thenominal rope diameter.
The minimum length of plain rope between the tails of splices shall be at least 15 times the nominal rope diameter. NOTE A stirrup can be fitted to protect the bearing surface of the soft eye. Standare working load limit of any intermediate link fitted to a three-leg or four-leg sling shall be at least equal to 1,6times the WLL of one of the legs suspended from it.
Where forged steel lifting hooks with latch grade 8, forged steel self-locking hooks grade 8, links grade 8,forged steel lifting hooks with latch grade 4, links grade 4 are used, they shall conform to EN parts 2 to 6respectively. Where shackles are used they shall conform to EN Where a terminal fitting is used, the eye termination shall always be fitted with a thimble.
For ferrule secured terminations KT shall be 0,9 and for spliced terminations KT shall be 0,8. Values of working load limits for the more common rope sizes in grade shall be in accordance with those given in Tables 3 and 4. Two ferrules appropriate to thediameter of the rope shall be pressed in accordance with prEN The adjacent ends of the ferrules shall notbe less than three times the length of the ferrule apart after pressing. Eachend shall be spliced back into the main body of the sling.
The splicing operation shall be in accordance with EN! NOTE This calculation assumes that endless slings will normally be used in choke hitch 2 x 0,8. The effect of choke is thedominant factor and thus takes precedence over the termination efficiency since the factors are not cumulative. Values of working load limits for the more common rope sizes shall be in accordance with those given in Tables 3and 4. The rope size type and grade foreach leg shall be the same. The legs of two-leg slings shall be joined at their upper ends by a master link see Figure 1.
In a three-leg sling,two of the legs shall be joined by a single intermediate master link to the master link, the third leg shall beconnected via a second intermediate master link.
In a four-leg sling each of the two pairs shall be joined by anintermediate master link to the master link. Upper eyes shall always be fitted with thimbles, and if lower terminal fittings are used, the eyes shall always befitted with thimbles. Thimbles shall conform to EN The lower terminal fittingscan be any of those shown in Table 2.
KL is the leg factor relating to the number of legs and the angle to the vertical see Table 3. KT is a factor which allows for the efficiency of the termination.

NOTE 2 Tables 3 and 4 show working load limit values for ferrule-secured eye slings in various configurations. NOTE 2 Table 3 shows working load limit values for ferrule-secured eye slings in various configurations. These values,which are based on the equation given in 5. NOTE 2 Table 4 shows working load limit values for ferrule-secured eye slings in various configurations.
The length of a single leg sling and the length of the individual legs of multi-leg slings shall be measured withoutload and with the widths of soft eyes being approximately half their length.
This shall identify the sling with the certificate andinclude a statement that the sling conforms to this European Standard. The certificate shall contain at least the following information. Thus the working load limit of a sling rated by this method is a variable dependent on the angle to thevertical of each leg such that as the angle increases the working load limit of the sling decreases.
The method of rating slings for general service used in this standard removes the need for calculation or the use oftables since the sling has a fixed working load limit for a given range of angles. The working load limit of the slingdoes not increase as the angle to the vertical decreases. Hence a sling has a fixed working load limit at all anglesbetween 0 and 45 and the same sling has a lesser working load limit at all angles between 45 and Since the upper terminal of the sling assembly, e.
This method of rating assumes that each leg is at the same angle to vertical, that for three and four leg slings thelegs are equally disposed when viewed in plan, and that all of the legs are in use.
The WLL of a 4 leg sling iscalculated assuming that one leg is redundant. Compliance with this document provides one means of conforming with the specific essential requirements of theDirective concerned and associated EFTA regulations.
