Full title and description

STB BS EN 13411-3:2022 — Terminations for steel wire ropes. Safety. Part 3: Ferrules and ferrule‑securing. This standard specifies requirements for ferrule‑secured eye terminations and endless loops, including ferrule materials, dimensions, manufacturing quality control and type testing for ferrule‑secured systems used in lifting and general-purpose wire rope assemblies.

Abstract

BS EN 13411-3:2022 defines safety, performance and quality requirements for ferrules and the ferrule‑securing process used to form eyes and endless loops in stranded steel wire ropes. It covers permitted ferrule materials, test methods (tensile and fatigue), production and inspection controls, marking and documentation that the ferrule‑secured system designer must supply. The standard is intended to ensure safe, repeatable terminations with defined minimum efficiencies for lifting and load‑bearing applications.

Scope

This document deals with the requirements for ferrule‑securing of eye terminations (Flemish eyes and turn‑back eyes) and ferrule‑secured endless loops for stranded steel wire ropes manufactured after the publication date. It applies to ferrules made of non‑alloy carbon steel and aluminium, to rope diameters up to and including 60 mm and is intended for slings and rope assemblies used in general lifting and load‑bearing applications (including ropes covered by the EN 12385 series). The standard specifies type testing, production quality control, instructions to be supplied by the ferrule‑secured system designer, and the significant hazards and foreseeable misuse to be addressed.

Key topics and requirements

• Scope of application: ferrule‑secured Flemish eye, turn‑back eye and endless loop terminations for a wide range of rope types.
• Permitted materials: non‑alloy carbon steel (fully killed, normalized) and aluminium for ferrules; matching of ferrule material to rope grade (suitable for ropes up to grade 1960 where stated).
• Type testing requirements: designer (FSET) must carry out and document tensile and fatigue tests for each basic rope type and range (tests on lowest and highest metallic cross‑section factors as applicable).
• Tensile performance: ferrule‑secured terminations shall sustain at least 90% of the rope minimum breaking force in the specified tensile test (90% terminal efficiency / KT = 0.9 for slings).
• Fatigue performance: when subjected to the fatigue test (e.g., 75 000 cycles) followed by tensile testing, assemblies shall sustain at least 80% of the rope minimum breaking force (80% after fatigue for certain tests and configurations).
• Manufacture & quality control: requirements for ferrule tube material, seam‑free production (except defined exceptions), dimensional control, surface defect checks and post‑press inspection criteria.
• Ferrule‑securing process controls: guidance on rope preparation, positioning of the dead end, pressing procedures, tooling alignment and maintenance, removal of fins and dimensional limits for pressed ferrules.
• Documentation & marking: the ferrule‑secured system designer must supply instructions for use, type test evidence, material certificates, permissible markings and temperature limits.
• Safety & hazards: identification of significant hazards, foreseeable misuse, and design/production measures to reduce risk in accordance with EN ISO 12100 principles.
• Informative annexes: examples and guidance (e.g., an example oval aluminium ferrule design in an annex) and removal of harmonization annexes in the 2022 revision where applicable.

Typical use and users

Primary users include ferrule and swaging equipment manufacturers, wire rope and sling manufacturers, lifting equipment designers, rigging and lifting inspectors, competent authorities and test laboratories. The standard is used when designing, type‑testing, manufacturing and certifying ferrule‑secured terminations for cranes, hoists, winches, slings and general load‑bearing wire rope assemblies.
