Full title and description

ISO 10056:2001 — Mechanical vibration — Measurement and analysis of whole-body vibration to which passengers and crew are exposed in railway vehicles. The standard defines field-test measurement and analysis procedures for periodic, random and transient whole‑body vibrations affecting seated and standing occupants in rail vehicles.

Abstract

This International Standard specifies how to measure and analyse whole‑body vibration in railway vehicles over the frequency range 0.5 Hz to 80 Hz, describing measurement locations, sensor mounting, measurement directions and durations, calculation of frequency‑weighted root‑mean‑square (r.m.s.) accelerations, a statistical analysis method and the recommended contents of a test report. It provides an informative example test report (Annex A) but does not itself prescribe methods for assessing physiological effects of vibration (those are covered by ISO 2631 series).

Scope

Defines a method for measuring and analysing whole‑body vibrations transmitted to passengers and crew in railway vehicles during field tests. Covers vibrations in the 0.5 Hz to 80 Hz band for seated and standing positions only. Excludes hand‑arm vibration and very‑low‑frequency lateral/vertical/rotational motions associated with kinetosis (motion sickness). The standard does not provide health‑effect evaluation criteria, which are addressed by ISO 2631‑1 and related parts.

Key topics and requirements

• Measurement scope and targeted frequency band (0.5–80 Hz), and applicability to seated and standing occupants.
• Recommended measuring equipment characteristics, sensor mounting and calibration requirements for accelerometers and conditioning chains.
• Preferred measurement locations (floor/platform points and seat contact points), measurement directions (typically x, y, z), and mounting/attachment details.
• Procedures for calculating frequency‑weighted r.m.s. accelerations and statistical analysis methods for time‑series vibration data.
• Minimum measurement durations, data‑block and averaging recommendations, and presentation of results.
• Contents and format guidance for the test report, plus an informative example report in Annex A.

Typical use and users

Used by railway vehicle designers and manufacturers, NVH (noise, vibration and harshness) engineers, testing laboratories, railway operators and safety/regulatory authorities to characterise ride vibration environments and to produce consistent field‑test reports for vehicle development, acceptance testing and comparative assessments. Although ISO 10056:2001 provided railway‑specific measurement detail, its measurement content has been integrated into later versions/amendments of ISO 2631‑4.

Related standards

ISO 2631 series (Evaluation of human exposure to whole‑body vibration) — in particular ISO 2631‑1 (general methods) and ISO 2631‑4 (fixed‑guideway transport systems); ISO 10056:2001 has been superseded by material incorporated into ISO 2631‑4:2001/Amd 1:2010. National/adopted versions include GB/T 13670 (China) which adopted ISO 10056:2001 text and later national standards aligning with ISO 2631‑4.

FAQ

Q: What is this standard?

A: ISO 10056:2001 is an ISO International Standard that specified procedures for measuring and analysing whole‑body vibration to which passengers and crew are exposed in railway vehicles. It was published in August 2001.

Q: What does it cover?

A: It covers field measurement and analysis procedures for periodic, random and transient whole‑body vibrations in the 0.5–80 Hz frequency range for seated and standing occupants, including recommended sensors, mounting, measurement directions, calculation of frequency‑weighted r.m.s. values, statistical processing and the structure of a test report. It does not provide health‑effect criteria.

Q: Who typically uses it?

A: Railway vehicle designers and manufacturers, NVH and test engineers, independent test laboratories, railway operators and standards/regulatory bodies use the measurement and reporting guidance for vehicle development, acceptance testing and comparative assessments.

Q: Is it current or superseded?

A: ISO 10056:2001 has been withdrawn. Its measurement and statistical analysis content was incorporated into ISO 2631‑4 (and specifically into ISO 2631‑4:2001/Amd 1:2010), so users should reference the relevant parts and amendments of the ISO 2631 series for current, authoritative guidance.

Q: Is it part of a series?

A: Yes — it relates to the ISO 2631 series (Evaluation of human exposure to whole‑body vibration). ISO 10056:2001 was a railway‑focused complement to ISO 2631‑1 and has since been folded into ISO 2631‑4 amendments.

Q: What are the key keywords?

A: Whole‑body vibration; railway vehicles; measurement; r.m.s. weighted acceleration; accelerometer mounting; field tests; NVH; statistical analysis; test report.
