DIN 81860-2 2022-12 PDF

Full title and description

DIN 81860-2:2022-12 — End fastenings for anchor chain cables on ships - Part 2: Components (German title: Endbefestigungen für Ankerketten auf Schiffen - Teil 2: Einzelteile). This part of DIN 81860 specifies the design details for the individual components used to form the inboard end fastenings of anchor chain cables fitted in chain lockers on ships.

Abstract

This standard defines the dimensions, constructional features and component requirements for end-fastening assemblies used to secure anchor chain cables inside chain lockers. Part 2 addresses the individual components (plates, pins, lock plates, knaggen, end connectors and similar items), their dimensional tables and material options as updated in the 2022 edition. The document updates earlier sizes and materials to reflect current shipbuilding practice.

Scope

This standard specifies the dimensions and construction of the components for end fastenings of anchor chain cables in chain lockers on ships. It is intended to ensure interchangeability and safe function of the inboard end connection components for studlink and compatible studless chain arrangements used in merchant and other seagoing vessels.

Key topics and requirements

• Dimensional tables and standardized shapes for individual components used in end fastenings (plates, lock plates, pins, knaggen, end connectors, etc.).
• Construction requirements to ensure correct fit and safe operation inside chain lockers.
• Updated nominal chain sizes included (extension of tables to cover additional sizes up to the listed range).
• Material specifications and additions (including the option of shipbuilding steel grade GL‑D where indicated).
• Specific dimensional additions such as knaggen dimensions for anchor-stem chains of higher grades (e.g., K4) and editorial clarifications compared with the 1999 edition.

Typical use and users

Used by shipbuilders, naval architects, ship outfitters, chain and deck equipment manufacturers, classification societies, yards and procurement/specification engineers when selecting or manufacturing end-fastening components for anchor chains. The standard is referenced in design, procurement and type-approval documentation for deck anchoring gear.

Related standards

Key related documents and standards commonly used together with DIN 81860-2 include: DIN 81860-1 (Part 1: Assembly — requirements for complete end fastening assemblies and their use on ships), DIN 81846 (chain grades and related provisions), DIN 81850 (end link dimensions) and EN standards for studless chains (e.g., EN 14330) where dimensional compatibility is required. Users should consult Part 1 for assembly-level requirements and relevant chain standards when applying Part 2 component specifications.

FAQ

Q: What is this standard?

A: DIN 81860-2:2022-12 is the part of the DIN 81860 series that defines the individual components used for inboard end fastenings of anchor chain cables on ships (i.e., the component-level specification for end fastenings).

Q: What does it cover?

A: It covers dimensions, constructional details and material options for the component parts (plates, pins, lock plates, knaggen, end connectors and similar items) that together form an end fastening inside a chain locker. It does not replace assembly-level requirements covered in Part 1.

Q: Who typically uses it?

A: Shipbuilders, outfitters, manufacturers of deck and anchoring equipment, classification societies, and procurement/specification engineers use this standard when designing, ordering or certifying end-fastening components.

Q: Is it current or superseded?

A: The 2022-12 edition is the current edition; it replaces the previous DIN 81860-2:1999-05 and includes dimensional updates, expanded nominal sizes and additional material options.

Q: Is it part of a series?

A: Yes — DIN 81860 is a series. Part 1 covers assembly-level requirements for end fastenings; Part 2 (this document) covers individual components. Other chain and chain-component standards (DIN 81846, DIN 81850, EN 14330, etc.) are commonly used alongside the series.

Q: What are the key keywords?

A: Anchor chain, end fastening, chain locker, components, DIN 81860, deck equipment, knaggen, end connector, GL‑D, K4.
