21、troduction This European Standard is a type C standard as stated in EN 12100. This European Standard has been prepared to provide a means of conforming with the essential safety requirements of the Machinery Directive and the Lift Directive and associated EFTA regulations. The wedge socket concerned
22、 and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this standard part of the standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take prec
23、edence over the provisions of the other standards for symmetric wedge sockets that have been designed and produced according to the provisions of this type C standard. Purchasers ordering to this standards are advised to specify in their purchasing contract that the supplier operates a quality assur
24、ance system applicable to the relevant part of this standard (e.g. EN ISO 9001) to ensure themselves that products claiming to comply consistently achieve the required level of quality. BS EN 13411-7:2006+A1:2008EN 13411-7:2006+A1:2008 (E) 5 1 Scope This European Standard specifies the minimum requi
25、rements for symmetrical wedge socket terminations for stranded steel wire ropes conforming to EN 12385-5 for lifts. This European Standard covers those symmetric wedge sockets intended for use at temperatures between -20 C and 100 C. This European Standard only covers those symmetric wedge sockets t
26、hat have welded socket bodies. An example of the construction and sizes of a symmetric wedge socket is given in informative Annex A. The informative Annex B gives the recommendations for the safe use and inspection of symmetric wedge socket according to Annex A. This European Standard deals with all
27、 significant hazards, hazardous situations and events relevant to symmetric wedge sockets for terminations for steel wire ropes, when used as intended and under conditions of misuse which are reasonable foreseeable by the manufacturer. The hazards covered by this European Standard are identified in
28、Clause 4. This European Standard applies to symmetric wedge sockets, which are manufactured after the date of its publication. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、the longitudinal axis of the live portion of the rope 3.2 socket body principal component of a wedge socket termination having an internal tapered form suitable for receiving a wedge (see 3.3) and the rope with which the wedge is associated, see Figure A.1 3.3 wedge flat tapered component with perip
36、heral groove, suitable for fitting into a tapered socket body to accommodate a rope of matching nominal diameter, see Figure A.1 3.4 pin removable component intended to facilitate connection of the socket body to its anchorage point 3.5 lot number of symmetric wedge sockets from which samples are se
37、lected for testing purposes which are of the same type and dimension, each of their constituent components manufactured during the same production run from material of the same cast and subjected to the same heat treatment process 4 List of significant hazards This European Standard contains all the
38、 significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of steel wire rope termination that require action to eliminate or reduce the risk. In particular, the hazard caused by accidenta
39、l release of a load, or release of a load due to failure of a symmetric wedge socket, puts at risk, either directly or indirectly, the safety or health of those persons within the hazard zone. Errors in the fitting of accessories can also lead to premature failure and this European Standard contains
40、 dimensional and geometrical requirements to allow correct fit. Table 1 contains those hazards that require action to reduce risk identified by risk assessment as being specific and significant for symmetric wedge sockets.
