Overview
EN 13146-9:2009/FprA1 - published by CEN - defines laboratory test procedures for determining the static and dynamic stiffness of rail pads, baseplate pads and complete rail fastening assemblies used in railway track systems. The standard covers measurement of stiffness across low and high frequencies, specifies symbols and procedures, and amends the original EN 13146-9:2009 with corrected equations and method clarifications (draft amendment FprA1, May 2011). It supports objective evaluation of fastening-system mechanical behaviour for design, quality control and noise/vibration assessment.
Key topics and technical requirements
- Scope: Laboratory test methods to determine static and dynamic stiffness of rail pads, baseplate pads and complete fastening assemblies.
- Frequency coverage: Dynamic stiffness procedures address both low and high frequency ranges; the direct reference method (EN ISO 10846-2) is specified up to 400 Hz (amendment updated from 450 Hz).
- Test methods: Includes the direct method (reference), indirect method, and corrected driving point method for assembling and interpreting stiffness data.
- Procedural precision: Amendment FprA1 updates symbols, mathematical expressions and specific procedural equations used to compute static and dynamic stiffness values, and adds definitions for measurement outputs (e.g., high-frequency assembly acceleration terms).
- Laboratory context: Procedures are specified as controlled laboratory tests, requiring appropriate instrumentation for force, displacement and acceleration measurement across the stated frequency bands.
Applications
- Product development and R&D for rail pads, baseplate pads and fastening assemblies - characterising stiffness behaviour under static loads and dynamic excitation.
- Factory and type-testing for quality control and acceptance testing of fastening components.
- Track design and maintenance: selecting and validating fastening systems to meet performance targets for track stiffness, ride quality and structure-borne noise/vibration.
- Procurement and specification: providing standardised stiffness metrics for tender documentation and compliance verification.
Who uses this standard
- Rail infrastructure engineers and track design teams
- Test laboratories performing mechanical and dynamic characterisation
- Fastening-system and component manufacturers
- Approval authorities, product certification bodies and procurement specialists
- Acoustic and vibration consultants assessing track-borne noise mitigation
Related standards
- EN ISO 10846-2 (referenced as the direct method up to 400 Hz)
- Other parts of EN 13146 series (test methods for fastening systems) and EN standards covering rail track components and track testing
