-20 °C and 100 °C. This European Standard only covers those symmetric wedge sockets that 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 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 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.

EN ISO 12100-2:2003, EN 12385-2:2002 and the following apply. 3.1 symmetric wedge socket assembly consisting of a socket body, wedge, and pin and securing means for the pin; when assembled the centre line of the pin is marginally offset (by one half rope diameter, see Figure B.1) to 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 peripheral 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 selected 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 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 accidental 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 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. SIST EN 13411-7:2006+A1:2008

The person who supervises the production process shall be trained in the chosen welding process. The quality of the welding joint shall be in accordance with assessment group B of EN ISO 5817:2003. There shall be no melted on weld chips. The ligament distance in the root of the welding joint shall be 1 mm for material thickness up to 6 mm and
1,5 mm for material thickness more than 6 mm up to and including 12 mm. The penetration of the root of the welding shall be avoided. There shall be no increase of the welding joint in the area of contact with the rope. The welding joint shall have a bonding area of a
