Terminations for steel wire ropes - Safety - Part 4: Metal and resin socketing
This European Standard specifies the minimum requirements for the molten metal and resin socketing of steel wire ropes conforming to prEN 12385 parts 4 to 10.
The standard covers only those requirements that ensure that the socketing is strong enough to withstand a force of at least 100 % of the minimum breaking force of the rope.
NOTE Rope terminations made by socketing in accordance with this European Standard can be used for determining the breaking force of wire ropes in accordance with annex A of prEN 12385-1:2001.
Socketing by the methods and materials described in this standard are for use within the temperature limits given in informative annex E.

Introduction
This European Standard has been prepared to provide a means of conforming with the essential safety requirements of
the Machinery Directive and associated EFTA regulations.
The methods of socketing described in this standard are based on historical experience and following them is
considered to result in a rope termination having an efficiency of 100 % based on the minimum breaking force of the
rope.
It is assumed that the included angle of the socket basket is not less than 9,5 nor greater than 18.
It is also assumed that the socket is
- suitable for heating without changing the characteristics of the socket material when the socketing medium is
molten metal;
- strong enough for the rope; and
- suitable for the purpose for which it is intended.
As the intended use of the rope should be known, resistance to fatigue loading is not covered.
While producing this standard it was assumed that negotiation occurs between the manufacturer and the user to decide
which socketing medium is required.

4 List of hazards
Accidental release of a load due to failure of the socketed portion of a socketed rope termination 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 of the socketed portion of a socketed termination this European
Standard gives requirements for the method of socketing to ensure specified levels of performance are met.
5 Safety requirements and/or measures
5.1 General
Socketing shall be carried out by a person trained in socketing.
5.2 Preparation of rope and socket
5.2.1 General
The position of the wires and strands of the non-socketed portion of rope shall remain undisturbed during the
socketing operation.
Oxyacetylene or similar cutting shall not be applied owing to risk of heat damage to the wires.
5.2.2 Marking
The rope shall be marked with the required length taking into account the length of the socket basket, the length of
the brush to be formed, any additional brush length for the hooking of wires and, if used, the depth of any
centralizing clamp.
5.2.3 Serving
The rope shall be served with a permanent serving as shown in Figure 1. Unless specified otherwise by the socket
manufacturer, the serving shall allow for penetration of the socketing medium between the served rope and the
bore of the socket.
The serving material shall be tinned or galvanized soft steel wire or strand.
5.2.4 Cleanliness of socket
The inside face of the socket basket shall not be contaminated.
NOTE This does not preclude the use of a releasing agent when socketing with resin.
5.2.5 Opening the brush
The rope (including any steel core where appropriate) shall be unlaid into its constituent wires to form an open
brush (see Figure 1).
NOTE During this operation, care should be taken to avoid excessive bending of the wires, particularly at the root of the
brush.
Any fibre core shall be removed from the whole length of the brush.
When socketing ropes with fibre cores with molten metal, the exposed end of the fibre core shall be protected from
the effects of heat.

EN 13411-4:2002 (E)
5.2.6 Pre-treatment of the brush
The brush shall be degreased to remove all traces of lubricant. Degreasing shall be by either liquid or vapour
methods.
Care shall be taken to ensure that degreasing is confined to the brush.
The wire brush shall be completely dry before the socketing medium is poured into the socket.
NOTE When socketing with lead-based alloys the wires of a bright rope may be pre-treated for improved adhesion. An
optional procedure is given in annex D.
5.2.7 Hooking
Where type testing shows that hooking is necessary, the dimensions of the hooked portion shall not be such that it
impedes the flow of the molten metal or resin during socketing, nor reduces the embedded length of the brush in
the socketing medium.
5.2.8 Positioning and alignment of brush, rope and socket
The socket shall be drawn over the brush until the root of the brush protrudes into the tapered portion at the small
end by no more than 0,5 d.
The wires shall be evenly distributed within the socket basket.
The distance between the end of the brush and the large end of the socket basket shall be no greater than 5 % of
the length of the socket basket.
If the ends of the wires at the top of the brush do not protrude beyond the large end of the socket basket, the actual
position of the wire ends in relation to the large end of the basket shall be measured and documented.
The rope axis shall be coinciden
