EN 1677-6:2001+A1:2008 (E) 4 Introduction This European Standard has been prepared to be a harmonized standard providing one means of complying with the essential safety requirements of the Machinery Directive and associated EFTA regulations. The links 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 such instances it is important that the link 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 Scope This part of EN 1677 specifies requirements for welded steel master links, intermediate master links, master link assemblies and lower terminal links of grade 4 up to 67 t WLL, mainly for use in:  chain slings according to EN 818-5  steel wire rope slings according to prEN 13414-1:1998  textile slings according to EN 1492-1, EN 1492-2. intended for lifting objects, materials or goods. The hazards covered by this Part of EN 1677 are identified in clause 4. 2 Normative 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, any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3 Terms and definitions For the purposes of this Part of EN 1677, the following terms and definitions apply.

3.1

working load limit (WLL) maximum mass that a link is authorized to sustain in general lifting service

NOTE This term has the same meaning as the term maximum working load used in the amendment to EN 292-2:1991/A1:1995. 3.2

manufacturing proof force (MPF) force applied to the link during the manufacturing proof test

3.3

breaking force (BF) maximum force reached during the static tensile test of the link at which the link fails to retain the load

3.4

sling assembly consisting of chain, wire rope or textile joined to upper and lower terminals suitable for attaching loads to the hook of a crane or other lifting machine

3.5

master link link forming the upper terminal of a sling by means of which the sling is attached to the hook of a crane or other lifting machine

3.6

intermediate master link link used to connect one or two legs of a sling to a master link

3.7

master link assembly assembly consisting of a master link together with two intermediate master links

3.8

lower terminal link, hook or other device fitted at the end of a leg of a sling, remote from the master

link or upper terminal
SIST EN 1677-6:2001+A1:2009
EN 1677-6:2001+A1:2008 (E) 6 3.9

traceability code series of letters and/or numbers marked on a link that enable its manufacturing history, including the identity of the cast of steel used, to be traced

3.10

lot specified number of links from which samples are selected for testing purposes, and that have been manufactured from the same cast of steel and subjected to the same heat treatment process

3.11

total ultimate elongation total extension at the point of fracture of the link expressed as a percentage of the internal length of the test sample

3.12

competent person designated person, suitably trained, qualified by knowledge and practical experience, and with the necessary instruction to enable the required test and examination to be carried out

NOTE 4.18 of EN ISO 9002:1994 gives guidance on training 4 Hazards Accidental release of a load, or release of a load due to failure of a link 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 links, this Part of EN 1677 gives requirements for the design, manufacture and testing to ensure that specified levels of performance are met. Fatigue failure has not been identified as a hazard when grade 4 links having the specified levels of performance given in this standard are used for general lifting purposes. Since failure can be caused by the incorrect choice of grade and specification of link, this standard also gives requirements for marking and the manufacturer's certificate. Errors in fitting can also lead to failure and this Part of EN 1677 contains dimensional requirements to allow correct fit. Risk of injury due to sharp edges, sharp angles or rough surfaces when handling is also covered by this standard. Those aspects of safe use associated with good practice are given in EN 818-6. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for links of grade 4.
