Full title and description

St IEC 61373-2010 cor1-2011 — Railway applications — Rolling stock equipment — Shock and vibration tests (IEC 61373:2010, Edition 2.0, with Corrigendum 1 issued 2011). This corrigendum corrects and clarifies elements of the 2010 edition relating to the shock and vibration test specification for equipment intended for use on railway vehicles.

Abstract

IEC 61373:2010 defines environmental test methods and pass/fail criteria for rolling‑stock equipment exposed to railway shock and vibration. Corrigendum 1 (2011) supplies editorial corrections and clarifications to the 2010 text so that test procedures, calculation methods and guidance are applied consistently by manufacturers, test houses and regulatory bodies. The standard supports the qualification of equipment to withstand operational vibration and shock throughout its expected service life.

Scope

Specifies requirements for testing items of equipment intended for use on railway vehicles to verify they withstand the shocks and vibrations encountered in service. The standard provides test procedures, severity classification by mounting location, and guidance for simulating lifetime exposure (including methods to accelerate service data such as amplification, time compression or decimation). Corrigendum 1 makes editorial corrections and clarifications to ensure consistent application of the 2010 edition.

Key topics and requirements

• Definition of mounting categories and severity levels for body, bogie and axle/shaft mounted equipment (used to determine test levels).
• Procedures for shock and vibration testing (broad‑band random vibration, functional shocks and specified shock pulses) and acceptance criteria for performance.
• Methods to simulate service exposure (amplification, time‑compression, decimation) when preparing test sequences from recorded service data.
• Technical changes introduced in the 2010 edition clarified by Corrigendum 1, including calculation of acceleration ratio, the concept of partial certification and guidance on computing functional RMS from service spectra.
• Requirements for mounting, instrumentation, measurement reference points and reporting to enable reproducible, auditable tests.

Typical use and users

Used by rolling‑stock equipment manufacturers, test laboratories, railway operators, procurement and certification authorities to qualify mechanical and electronic equipment for service on trains. It is typically applied alongside other rolling‑stock standards (for example EN 50155 / IEC 60571 for electronic equipment) when demonstrating environmental robustness for vehicle installations.

Related standards

FAQ

Q: What is this standard?

A: IEC 61373:2010 is an international standard that specifies shock and vibration test methods and acceptance criteria for equipment intended for use on railway rolling stock. Corrigendum 1 (2011) is a one‑page correction to the 2010 edition.

Q: What does it cover?

A: It covers test procedures (random vibration, functional shocks, specified shock pulses), classification by mounting location and severity, measurement and reporting requirements, and guidance for creating representative test sequences from service recordings. The corrigendum clarifies calculations and editorial issues from the 2010 text.

Q: Who typically uses it?

A: Equipment and component manufacturers, independent test laboratories, railway operators, procurement bodies and conformity assessment/certification organizations use the standard when qualifying products for rail vehicle installation.

Q: Is it current or superseded?

A: The base edition is IEC 61373:2010 (Edition 2.0) with Corrigendum 1 issued in October 2011. The IEC webstore lists the publication and a stability date for the 2010 edition; users should confirm whether a later revision (e.g., an ED3 or subsequent amendments) has been published before relying on the standard for new projects. As of the corrigendum's publication the document was active; check the IEC catalogue or national adoption bodies for the very latest status.

Q: Is it part of a series?

A: Yes — IEC 61373 is part of the family of railway and rolling‑stock standards maintained by IEC TC 9 and is commonly used alongside standards for electronic and environmental performance (for example IEC 60571 and EN 50155). National and regional bodies often publish identical or adopted versions (EN 61373 / BS EN 61373, etc.).

Q: What are the key keywords?

A: Shock, vibration, rolling stock, random vibration, shock pulse, acceleration spectral density, mounting category, equipment qualification, IEC 61373, corrigendum.
