What is BS EN 13411‑7 about?
BS EN 13411‑7 is the seventh in a multi-series of European standard. BS EN 13411-7 specifies the minimum requirements for symmetrical wedge socket terminations for stranded steel wire ropes conforming to EN 12385‑5 for lifts.
BS EN 13411‑7 covers those symmetric wedge sockets intended for use at temperatures between −20 °C and 100 °C.
BS EN 13411‑7 only covers those symmetric wedge sockets that have welded socket bodies.
BS EN 13411‑7 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 reasonably foreseeable by the manufacturer.
BS EN 13411‑7 applies to symmetric wedge sockets, which are manufactured after the date of its publication.
Who is BS EN 13411‑7 for?
BS EN 13411‑7 on symmetric wedge socket is relevant to:
- Manufacturer of steel wire ropes
- Wedge socket manufacturers
- Industries including but not limited to construction, manufacturing, mining etc
Why should you use BS EN 13411‑7?
A wedge socket is a type of hardware used to connect objects to a wire rope. They may be used to fasten the wire to the ground or to connect a hook or similar lifting mechanism to the end of the wire.
BS EN 13411‑7 provides information on significant hazards, safety requirements and protective measures, geometry of wedge and socket body, manufacturing tests and inspection of symmetric wedge socket.
Hazards and associated requirements have been identified in BS EN 13411‑7 to help you improve risk mitigation measures. Hazards include:
- Inadequate mechanical strength
- Errors of fitting
- Insecurity of components
- Failure arising from fatigue
- Inadequate low temperature properties
- Incorrect identification of components
- Inadequate information about the item
The information provided in BS EN 13411‑7 assists the user in manufacturing a wedge socket that can are compliant with standardized safety protocols that minimizes the risk of product failure.
What’s changed since the last update?
BS EN 13411‑7:2021 supersedes BS EN 13411‑7:2006+A1:2008, which is withdrawn. The main changes compared to the previous edition are listed below:
- A major change to the manufacturing test and examination regime and acceptance criteria
- Updates in standard references
- Coefficient of utilisation changed from 10:1 to 12:1 for lifting persons
