Inland navigation vessels - Studless anchor chain - Round steel link chain

This standard applies to round steel link chains with a pitch of 2,8 d of grade 2 from which studless anchor chains for inland navigation vessels are made with the relevant accessories, e.g. joining links, swivel shackles, swivels and end links.
This standard specifies dimensions, mechanical properties, data for designation, marking and test conditions.
NOTE   For relationship with other strength grades, see annex B.

Overview

EN 14330:2003 is a CEN European standard for studless anchor chains used on inland navigation vessels. It covers round steel link chains of strength grade 2 with a standard pitch of 2,8 · d and defines required dimensions, material and heat‑treatment rules, mechanical properties, testing, designation and marking for chains and their accessories (e.g. joining links, swivel shackles, swivels, end links). The standard is intended to ensure safe, consistent performance of anchor chains in inland waterways.

Key topics and technical requirements

• Scope and nominal size: Applies to round steel link chains (nominal size expressed as d × p) for studless anchor chains; pitch is p = 2,8 d.
• Dimensions and tolerances: Specifies diameter (d), weld diameter (ds between 1,0 d and 1,1 d), weld section length, pitch, internal/external widths (w1, w2) and gauge length rounding rules.
• Material and chemistry:
  • Steel from electric or oxygen‑blown processes.
  • Fully killed steel, resistant to ageing; grain size ≤ 5 (ISO 643).
  • Minimum 0,025 % Al to ensure resistance to ageing.
  • Maximum S and P limits given (cast & product analyses).
• Heat treatment: All welded round links must be heat treated by heating above the upper transformation point (Ac3).
• Mechanical properties and loads:
  • Manufacturing proof force (MPF) and breaking force (BF) values specified per nominal size.
  • Total ultimate elongation: ≥ 25 % for naturally black surface; ≥ 20 % for other surface conditions.
  • Deflection (bend) requirements with visual inspection for cracks/defects.
• Testing and sampling:
  • Manufacturing proof testing of whole chain.
  • Lot size = 200 m for sample selection (EN 818‑1 sampling rules).
  • Static tensile and bend tests per EN 818‑1; test machine and procedures specified there.
• Designation & marking:
  • Example: EN 14330 - 13 × 36 - 2 (standard - nominal size - strength grade).
  • Delivery units must be labeled with manufacturer, nominal size (d × p), strength grade, tensile force (kN) and reference to EN 14330.

Applications and users

Who uses EN 14330:

• Chain manufacturers and heat‑treatment shops for production and QA.
• Shipyards and marine equipment suppliers specifying studless anchor chain for inland vessels.
• Procurement teams and owners/operators of inland navigation vessels seeking compliant anchor gear.
• Testing laboratories, inspectors and conformity assessors performing tensile and bend tests.
• Regulatory bodies and classification/flag authorities referencing technical requirements for inland navigation safety.

Practical value:

• Ensures consistent safety margins and interchangeability of anchor chain components.
• Facilitates procurement and conformity assessment with clear designation and marking rules.
• Reduces risk of premature chain failure by specifying metallurgy, heat treatment and mechanical acceptance tests.
