Overview

EN 14606:2004 (CEN) - "Inland navigation vessels - Studless anchor chain - Accessories" defines requirements for accessories used with round steel studless anchor chains (as specified in EN 14330) on inland navigation vessels. The standard specifies the construction, dimensions and testing of accessories that connect the chain to anchors and swivels, and it clarifies the scope by excluding items such as cable stoppers, cable lockers and certain end fastenings.

Key topics and technical requirements

• Components covered: joining links, common links, enlarged links, end links, chain swivels, end shackles, swivel shackles and Kenter‑type joining shackles.
• Construction & materials: requirements for component geometry, forging tolerances and material selection are given to ensure fit and mechanical compatibility with studless round chain.
• Dimensions & masses: detailed figures and tabulated nominal dimensions/masses for standard nominal sizes (d × p) are provided, including formulas used to calculate key dimensions (see annexed tables and figures).
• Mechanical properties & strength: the document includes requirements for strength and mechanical properties of accessories and prescribes testing routines (strength tests and dimensional verification) to confirm conformity.
• Assembly & marking: rules for assemblies (anchor swivels, swivel outboard shots, etc.), designation and marking are included to ensure traceability and correct matching with EN 14330 chains.
• Normative references: cross‑references to EN 14330 (studless anchor chain), ISO 1704, EN 10243, EN 22339 and other relevant standards for fasteners and tolerances.

Practical applications and users

EN 14606 is intended for anyone involved in the specification, manufacture, fit‑out, inspection and maintenance of anchor gear for inland vessels:

• Chain and accessory manufacturers (for design and production to standardized dimensions)
• Shipyards and marine equipment suppliers (for procurement and installation)
• Naval architects and vessel designers (for correct selection and interfacing with anchor systems)
• Classification societies, surveyors and fleet operators (for inspection, testing and compliance)
• Maintenance teams (for replacement parts and compatibility checks)

Using EN 14606 ensures safe, interchangeable connections between studless anchor chains and anchor/swivel assemblies on inland navigation vessels.

Related standards

• EN 14330 - Studless anchor chain (round steel chain)
• ISO 1704 - Shipbuilding - Stud‑link anchor chains
• EN 10243, EN 22339, EN ISO 7046-2 - related forging, fastener and pin tolerances/tests
