Overview

EN 13230-3:2016 - published by CEN - is the European standard for railway applications covering twin-block reinforced concrete sleepers. It defines the technical criteria, manufacturing controls and testing procedures required for the production and acceptance of twin-block reinforced sleepers. EN 13230-3:2016 supersedes the 2009 edition and is one part of the EN 13230 series for concrete sleepers and bearers.

Key facts:

• Title: Railway applications - Track - Concrete sleepers and bearers - Part 3: Twin-block reinforced sleepers
• Approved by CEN: 4 March 2016
• Supports essential requirements of EU Directive 2008/57/EC (see informative Annex ZA)
• Intended to be used alongside EN 13230-1:2016 (General requirements)

Key Topics

This part focuses on the specific requirements for twin-block reinforced sleepers. Major technical topics and requirements include:

• Test arrangements and procedures: defined layouts and methods for rail seat section testing (static and dynamic), including positive and negative bending moment tests and load application set-ups.
• Acceptance criteria: criteria for first-crack loads, crack-width limits and maximum permissible loads after unloading.
• Design approval tests: rules for bending moment evaluation and product inspection required for design validation.
• Steel connecting bar: specifications for the steel connecting bar (definition, chemical and mechanical properties, geometry, appearance), design criteria for incorporation in the sleeper and acceptable defects (Annex B).
• Manufacturing and routine tests: production control rules, routine static rail seat positive load tests and concrete testing requirements.
• Test components and accessories: details of articulated supports, resilient pads and tapered packings used in test arrangements (Annex A).
• Terminology update: wording change from “design bending moment” to “characteristic bending moment” and “test bending moment”.

Applications

EN 13230-3:2016 is used to ensure consistent performance and safety of twin-block reinforced sleepers in rail track applications. Typical users include:

• Sleeper manufacturers - for production control, design validation and routine testing.
• Testing laboratories - to perform standardized static and dynamic rail seat tests and certify compliance.
• Railway infrastructure managers and contractors - to specify procurement requirements and acceptance criteria for track components.
• Design engineers and conformity assessors - to evaluate bending moments, steel connecting bar integration and overall compliance with EU railway interoperability requirements.
