Overview
EN 13411-7:2021 - Terminations for steel wire ropes - Safety - Part 7: Symmetric wedge socket - is a CEN safety standard that specifies minimum requirements for symmetric wedge socket terminations used with stranded steel wire ropes for lifts (see EN 12385-5). It applies only to symmetric wedge sockets with welded socket bodies, intended for service temperatures between −20 °C and 100 °C, and covers design, testing, manufacture, marking and information for safe use.
Key topics and requirements
- Scope and applicability: Covers welded-body symmetric wedge sockets manufactured after the standard’s publication; informative examples in Annex A and safe-use guidance in Annex B.
- Geometry and fit: Dimensional and geometric criteria to prevent fitting errors - e.g., clamping length ≥ 7.3 × nominal rope diameter (d) and wedge groove radius at the large end ≥ 1 × d.
- Security of components: The pin must have secure retaining means when in service.
- Weld quality: Welding processes per EN ISO 4063; welds assessed to EN ISO 5817 assessment group B; no melted-on weld chips; qualified welding supervision required.
- Mechanical properties & safety factors: Requirements for termination efficiency, fatigue behaviour, and low-temperature performance. Notable update: coefficient of utilisation for lifting persons updated to 12:1 (previously 10:1).
- Verification & testing: Type testing regime includes tensile efficiency tests, fatigue testing, Charpy impact tests for low-temperature properties, and manufacturing examinations (visual, magnetic particle or penetrant NDT per EN ISO 17638 / EN ISO 23277).
- Information for use: Mandatory marking, fitting instructions, and manufacturer’s certificate to ensure correct assembly and traceability.

La norme EN 13411-7:2021 précise les exigences minimales pour les terminaisons à embase symétrique utilisées avec des câbles en acier toronnés, conformément à la norme EN 12385-5, destinée aux ascenseurs. Cette documentation est cruciale pour garantir la sécurité dans les applications industrielles et de levage, en établissant un cadre fiable pour la fabrication et l'utilisation des embases symétriques. L'une des grandes forces de cette norme réside dans sa couverture des températures d'utilisation, allant de -20 °C à 100 °C, ce qui permet d'assurer la performance des terminaisons dans une large gamme d'environnements. De plus, la norma se limite aux embases symétriques ayant des corps soudés, ce qui renforce la sécurité en nécessitant une intégrité structurelle pour les applications à fort risque. Le document identifie également toutes les dangers et situations dangereuses associées aux embases symétriques, en tenant compte des usages prévus ainsi que des abus raisonnablement prévisibles, ce qui témoigne d'une approche pro-active en matière de gestion des risques. Ce niveau de détail offre une confiance accrue aux utilisateurs finaux, en leur permettant de mieux comprendre les situations à risque et comment les éviter. Les annexes informatives fournissent des exemples de constructions et de dimensions, ainsi que des recommandations pour l'utilisation et l'inspection sécuritaires des embases à embase symétrique.
