Test methods - Timber floors - Determination of vibration properties

This document specifies test methods for the determination of natural frequencies, damping, unit point load deflection and acceleration of floors composed of sawn timber, engineered wood products, and mass timber beams or slabs (e.g. cross laminated timber CLT, glued laminated timber GL, nail laminated timber), with or without concrete screeds, as well as for timber-concrete composite floors.

Overview

EN 16929:2018 - Test methods - Timber floors - Determination of vibration properties is a CEN standard that defines laboratory and in situ test methods to measure the dynamic behaviour of timber floors. It covers measurement of natural frequencies, damping, unit point load deflection and floor acceleration for floors made from sawn timber, engineered wood products and mass timber (e.g. CLT, glulam, nail‑laminated timber), with or without concrete screeds and for timber–concrete composite floors.

The standard addresses why vibration matters (human comfort, equipment sensitivity), limits the frequency range of interest (practical effects are typically below 40–50 Hz; floors with fundamental frequency < 8 Hz are considered low‑frequency and susceptible to resonance), and requires testing by competent personnel experienced in structural dynamics.

Key topics and requirements

• Scope of testing: natural/fundamental frequency, modal behaviour, damping ratio, static unit point load deflection and acceleration responses.
• Specimen preparation: determination of floor dimensions, moisture content and overall floor mass, and conditioning prior to testing.
• Test environments: procedures for both laboratory testing and in situ testing (on-site measurements).
• Test setups: guidance on support detailing, sensor and excitation placement, and required apparatus for reliable measurement.
• Measurement methods: stepping/excitation tests, mass drop and other accepted excitation techniques to derive frequency and damping; procedures to obtain acceleration and deflection results.
• Results and reporting: standardized presentation of measured fundamental frequency, damping ratio, deflection under unit point load and acceleration time/harmonic metrics, plus required test report content.
• References: normative links to moisture measurement and human vibration evaluation standards (see Related Standards).

Applications

• Assessing pedestrian-induced vibration and comfort in offices, auditoria, galleries and residential buildings.
• Verifying dynamic performance of long-span or lightweight timber floors, including CLT and timber–concrete composite systems.
• Product performance validation for manufacturers of engineered wood floors and acoustic/flooring consultants.
• Design input for structural engineers to refine serviceability checks where standard static deflection limits are insufficient.
• Supporting retrofit decisions and troubleshooting vibration complaints in existing timber structures.

Who should use EN 16929

• Structural engineers and timber‑frame designers
• Test laboratories and certification bodies
• Manufacturers of mass timber and engineered wood products
• Building acoustics and vibration consultants
• Research institutions studying floor dynamics

Related standards

• EN 13183 (all parts) - Moisture content of sawn timber
• EN 322 - Wood‑based panels - Determination of moisture content
• ISO 2631‑1 - Evaluation of human exposure to whole‑body vibration

EN 16929 is essential when accurate, repeatable measurement of timber floor vibration properties is required for design validation, compliance, or occupant comfort assessments.
