3.2 socket body principal component of a wedge socket termination having an internal tapered form (see Figure 1) suitable for receiving a wedge (see 3.3) and the rope with which the wedge is associated 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 1 SIST EN 13411-6:2004+A1:2008

The difference between the wedge angle (α) and the socket angle (β) shall be not greater than 2°. The internal side surfaces of the socket body and the wedge in contact with the rope shall be straight. The clamping length between socket body and the wedge in contact with the live portion of the rope shall be a minimum length (P) equal to 4,3 times the nominal rope diameter.
The rope groove in the socket body and the wedge shall not exhibit protrusions, marks or casting joints that would affect the intimate contact with the rope.

5.3.3 Fatigue behaviour of the socket body and pin When tested in accordance with 6.2.4 the socket body and pin shall not exhibit any indications of cracks after 75000 load cycles.
The socket shall also exhibit no sign of local permanent deformation in the pin eye holes. 5.3.4 Termination efficiency When tested in accordance with 6.2.5 the efficiency of the assembled termination shall be at least 80% of the minimum breaking force of the rope. 5.3.5 Low temperature properties The materials of the socket, body and pin when tested in accordance with 6.2.6 shall possess minimum low temperature ductility and toughness qualities at –20°C as follows:  Steel socket body and/or pin: Minimum average Charpy impact value of 27 J, with no individual value less than 18 J.  Spheroidal graphite cast iron and any other cast irons: socket body: Minimum average Charpy impact value of 12 J, with no individual value less than 9 J.
6.2.2 Termination and wedge security test Subject the assembled termination to a load of 20% of the minimum breaking force of the rope, sustain this load for an initial period to allow settlement of the termination, then continue to sustain for a further 2 min before removing the load. 6.2.3 Deformation test The termination shall be further loaded until this load reaches a value equal to 40% of the minimum breaking force of the rope. The load shall then be removed, the termination dismantled and the socket body and pin examined for permanent deformation. 6.2.4 Fatigue test The test shall be carried out on an in-line tensile fatigue machine. The termination shall be prevented from rotating and the test shall consist of the application of the cycle force from 15% to 30% of the minimum breaking force of the rope along the rope axis for 75000 cycles. The frequency of the force shall not exceed 5 Hz. The component parts shall be submitted to either dye penetrant or magnetic particle inspection in accordance with EN 1369 or EN 1371-1 both before and after the fatigue test to enable any crack initiation and propagation as a result of fatigue to be readily identified. NOTE More than one rope may be required to enable the socket body to achieve 75000 cycles. 6.2.5 Tensile efficiency test Subject the assembled termination to an initial load of 60% of the minimum breaking force of the rope, then increasing this load at a rate of not more than 0,5% of the breaking force per second.
The test shall be continued until either rope slip or breakage occurs.
If terminations are tested in pairs, the distance between the inner faces of the socket bodies shall be at least 30 d. SIST EN 13411-6:2004+A1:2008

If one sample fails to meet the specified individual value or if the average of the three individual values fails to meet the specified average value, two further samples shall be taken and both shall pass the individual value test and the average of the five samples shall pass the average test in order for the respective component of the size submitted for type testing to be deemed to conform to this European Standard. If two or three samples fail to meet the specified individual value, the respective component of the size submitted for type testing shall be deemed not to conform to this European Standard. 6.3 Manufacturing tests 6.3.1 Manufacturing proof test The socket body and pin shall be subjected to the manufacturing proof force equal to a load of 40% of the highest minimum breaking force of rope for which the socket is designed. This shall be sustained without deviating
