3 Terms and definitions For the purposes of this European Standard the terms and definitions given in EN 10025: 1990 and the following apply: 3.1 shackle a lifting accessory comprising a body and pin as shown in Figures 1 and 2 which are readily separable and can be used to connect a load to a lifting machine directly or in conjunction with other lifting accessories.
3.2 body a part of the shackle formed to the shape of a dee or bow and terminating in eyes as shown in Figures 1 and 2.
3.3 pin a component of circular section which passes through the eyes of the shackle, as shown in Figures 1, 2 and B.1 and which can be readily disassembled.
3.4 dee shackle a shackle the crown of which forms a semicircle of internal radius half the width, W, between the eyes as shown in Figure 1. 3.5 bow shackle a shackle the crown of which forms more than a semicircle of internal radius more than half the width, W, between the eyes as shown in Figure 2. 3.6 working load limit WLL maximum mass that a shackle is authorized to sustain in general service NOTE This term has the same meaning as the term maximum working load used in EN 292-2: 1991, annex A. 3.7 manufacturing proof force MPF force applied to the shackle during the manufacturing proof test 3.8 breaking force BF maximum force reached during the static tensile test of a shackle at which the shackle fails to retain the load 3.9 traceability code series of letters and/or numbers marked on a shackle that enables its manufacturing history, including identity of the cast of steel used, to be traced
3.10 lot number of shackles of the same type and dimensions, manufactured during the same production run from the same cast of steel and subjected to the same heat treatment process
3.11 type W pin screwed pin with eye and collar and which screws into one eye of the shackle body
3.13 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 EN ISO 9001 gives guidance on training. 4 Hazards Accidental release of a load, or release of a load due to failure of shackle 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 shackles EN 13889 gives 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 shackle EN 13889 also gives the requirements for marking and the manufacturer's certificate. Errors of fitting can also lead to failure and EN 13889 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 annex A. Table 1 contains those hazards, which require action to reduce risk identified by risk assessment as being specific and significant for shackles.
