Full title and description

Mechanical vibration and shock — Evaluation of human exposure to whole-body vibration — Part 2: Vibration in buildings (1 Hz to 80 Hz). This International Standard specifies measurement and evaluation methods for whole‑body vibration and shock in buildings with respect to occupant comfort and annoyance, and defines the frequency weighting Wm applicable over 1 Hz to 80 Hz.

Abstract

ISO 2631-2:2003 gives guidance for measuring and evaluating building vibration affecting people (comfort/annoyance), including measurement directions and locations and a mathematical definition of the frequency weighting Wm. It is not intended to set acceptability limits, to assess structural damage, or to evaluate health and safety impacts; related guidance on structural effects is provided in ISO 4866. Annex A defines Wm mathematically and Annex B gives guidelines for collecting complaint data.

Scope

Specifies methods for measurement and evaluation of whole‑body vibration and shock occurring in buildings in the frequency range 1 Hz to 80 Hz for the purpose of assessing occupant comfort and annoyance. The standard defines appropriate measurement directions and locations and the frequency weighting Wm for this application. It does not address structural‑damage criteria or direct health/safety assessments.

Key topics and requirements

• Frequency range: evaluation targeted at 1 Hz to 80 Hz and use of the Wm frequency‑weighting curve.
• Measurement direction and location: guidance for selecting axes and positions (measure where occupants are or where maximum weighted vibration occurs).
• Measurement and evaluation procedures: standardized processing and reporting for building vibration surveys.
• Annex A: mathematical definition of the Wm weighting curve.
• Annex B: guidance for collecting and documenting occupant complaints about vibration (data collection and context).
• Limitations: does not specify acceptability limits, nor evaluate health effects; structural effects are covered by ISO 4866.

Typical use and users

Used by vibration/acoustics consultants, building engineers, architects, façade and structural specialists, facility managers, environmental health and safety professionals, and researchers conducting in‑situ vibration surveys or design‑stage predictions of building vibration. Typical applications include assessing annoyance and comfort from nearby sources (rail, road, industrial machinery), validating design predictions, and documenting complaint investigations.

Related standards

Part of the ISO 2631 series on whole‑body vibration; see ISO 2631‑1 (general requirements and evaluation methods) and other parts addressing specific frequency bands, transport systems, and multi‑shock vibration. ISO 4866 provides complementary guidance on vibration measurement and evaluation with respect to structural effects. National adoptions and EN/NF/BS versions exist that reproduce or reference ISO 2631‑2.

FAQ

Q: What is this standard?

A: ISO 2631-2:2003 is the part of the ISO 2631 series that specifies how to measure and evaluate whole‑body vibration and shock in buildings for the assessment of occupant comfort and annoyance.

Q: What does it cover?

A: It covers measurement directions and locations, processing and evaluation procedures, and defines the frequency weighting Wm applicable from 1 Hz to 80 Hz; it gives annex guidance (mathematical Wm in Annex A and complaint data in Annex B) but does not set acceptability limits or assess structural damage or health effects.

Q: Who typically uses it?

A: Vibration and acoustics consultants, building and structural engineers, architects, facilities and environmental health professionals, and researchers—anyone performing building vibration surveys or assessing occupant comfort related to vibration.

Q: Is it current or superseded?

A: The 2003 edition (Edition 2) is the published version; ISO records show the standard as published but under periodic review (status entries indicate it has been reviewed and in ISO lifecycle notation may be listed "to be revised"). Users should check national adoption status and any more recent replacements or drafts if precise currency is critical.

Q: Is it part of a series?

A: Yes — ISO 2631 is a multi‑part series addressing whole‑body vibration. Relevant parts include ISO 2631‑1 (general requirements) and other parts for specific conditions; ISO 4866 is a complementary standard for evaluating structural vibration effects.

Q: What are the key keywords?

A: Whole‑body vibration, building vibration, Wm weighting, measurement procedures, occupant comfort, annoyance, 1–80 Hz, ISO 2631.
