What is BS EN 13411‑4 about?
BS EN 13411‑4 specifies the minimum requirements for the molten metal and resin socketing of steel wire ropes within the scopes of EN 12385-4:2002+A1:2008; EN 12385-5:2021; EN 12385-6:2004; EN 12385-7:2002; EN 12385-8:2002; EN 12385-9:2002 and EN 12385-10:2003+A1:2008.
BS EN 13411‑4 applies only to 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 (i.e. socket termination efficiency factor KT = 1,0).
BS EN 13411‑4 deals with all significant hazards, hazardous situations and events relevant to metal and resin socket terminations, when they are used as intended and under reasonably foreseeable conditions of misuse.
NOTE: Rope terminations made by socketing in accordance with this document can be used for determining the breaking force of wire ropes in accordance with EN 12385-1:2002+A1:2008, Annex A.
Who is BS EN 13411‑4 for?
BS EN 13411‑4 on metal and resin socketing is relevant to:
- Manufacturer of steel wire ropes
- Socketing manufacturers
- Socketing designers
- Installers
Why should you use BS EN 13411‑4?
BS EN 13411‑4 provides information on a list of significant hazards, safety requirements and/or protective measures, preparation of rope and socket, cutting of rope, socketing, molten metal socketing, resin socketing.
Identification of hazards relevant by BS EN 13411‑4 has created awareness to mitigate or minimize the incidence of dangerous scenarios. Hazards include:
- Inadequate mechanical strength
- Errors of fitting
- Toxicity
- Noise
- Burns
- Puncture wonds
The hazard caused by 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, BS EN 13411-4 gives requirements for the method of socketing to ensure specified levels of performance are met.
The methods of socketing described in BS EN 13411‑4 are based on established procedures 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 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
- Suitable for the purpose for which it is intended
As a buyer of BS EN 13411‑4, you will be able to achieve a successful metal and resin socketing system by ensuring the high bond strength between the wire and metal/resin and high modulus of elasticity.
What’s changed since the last update?
BS EN 13411‑4:2021 supersedes BS EN 13411‑4:2011, which is withdrawn
This third edition incorporates both technical and editorial amendments, with the main changes
compared to the previous edition as follows:
- Re-draft hazards clause
- Include requirements to remove non-metallic components in the rope brush
- Deletion of heat distortion property requirement
- Comment on cone draw added
- Delete annex za and re-draft document to reflect the change in status to a de-harmonized standard
